+\page quick_start Quick start
+
+\section quick_start_project_setup Project setup
+
+Vulkan Memory Allocator comes in form of a "stb-style" single header file.
+You don't need to build it as a separate library project.
+You can add this file directly to your project and submit it to code repository next to your other source files.
+
+"Single header" doesn't mean that everything is contained in C/C++ declarations,
+like it tends to be in case of inline functions or C++ templates.
+It means that implementation is bundled with interface in a single file and needs to be extracted using preprocessor macro.
+If you don't do it properly, you will get linker errors.
+
+To do it properly:
+
+-# Include "vk_mem_alloc.h" file in each CPP file where you want to use the library.
+   This includes declarations of all members of the library.
+-# In exacly one CPP file define following macro before this include.
+   It enables also internal definitions.
+
+\code
+#define VMA_IMPLEMENTATION
+#include "vk_mem_alloc.h"
+\endcode
+
+It may be a good idea to create dedicated CPP file just for this purpose.
+
+Note on language: This library is written in C++, but has C-compatible interface.
+Thus you can include and use vk_mem_alloc.h in C or C++ code, but full
+implementation with `VMA_IMPLEMENTATION` macro must be compiled as C++, NOT as C.
+
+Please note that this library includes header `<vulkan/vulkan.h>`, which in turn
+includes `<windows.h>` on Windows. If you need some specific macros defined
+before including these headers (like `WIN32_LEAN_AND_MEAN` or
+`WINVER` for Windows, `VK_USE_PLATFORM_WIN32_KHR` for Vulkan), you must define
+them before every `#include` of this library.
+
+
+\section quick_start_initialization Initialization
+
+At program startup:
+
+-# Initialize Vulkan to have `VkPhysicalDevice` and `VkDevice` object.
+-# Fill VmaAllocatorCreateInfo structure and create #VmaAllocator object by
+   calling vmaCreateAllocator().
+
+\code
+VmaAllocatorCreateInfo allocatorInfo = {};
+allocatorInfo.physicalDevice = physicalDevice;
+allocatorInfo.device = device;
+
+VmaAllocator allocator;
+vmaCreateAllocator(&allocatorInfo, &allocator);
+\endcode
+
+\section quick_start_resource_allocation Resource allocation
+
+When you want to create a buffer or image:
+
+-# Fill `VkBufferCreateInfo` / `VkImageCreateInfo` structure.
+-# Fill VmaAllocationCreateInfo structure.
+-# Call vmaCreateBuffer() / vmaCreateImage() to get `VkBuffer`/`VkImage` with memory
+   already allocated and bound to it.
+
+\code
+VkBufferCreateInfo bufferInfo = { VK_STRUCTURE_TYPE_BUFFER_CREATE_INFO };
+bufferInfo.size = 65536;
+bufferInfo.usage = VK_BUFFER_USAGE_VERTEX_BUFFER_BIT | VK_BUFFER_USAGE_TRANSFER_DST_BIT;
+
+VmaAllocationCreateInfo allocInfo = {};
+allocInfo.usage = VMA_MEMORY_USAGE_GPU_ONLY;
+
+VkBuffer buffer;
+VmaAllocation allocation;
+vmaCreateBuffer(allocator, &bufferInfo, &allocInfo, &buffer, &allocation, nullptr);
+\endcode
+
+Don't forget to destroy your objects when no longer needed:
+
+\code
+vmaDestroyBuffer(allocator, buffer, allocation);
+vmaDestroyAllocator(allocator);
+\endcode
+
+
+\page choosing_memory_type Choosing memory type
+
+Physical devices in Vulkan support various combinations of memory heaps and
+types. Help with choosing correct and optimal memory type for your specific
+resource is one of the key features of this library. You can use it by filling
+appropriate members of VmaAllocationCreateInfo structure, as described below.
+You can also combine multiple methods.
+
+-# If you just want to find memory type index that meets your requirements, you
+   can use function: vmaFindMemoryTypeIndex(), vmaFindMemoryTypeIndexForBufferInfo(),
+   vmaFindMemoryTypeIndexForImageInfo().
+-# If you want to allocate a region of device memory without association with any
+   specific image or buffer, you can use function vmaAllocateMemory(). Usage of
+   this function is not recommended and usually not needed.
+   vmaAllocateMemoryPages() function is also provided for creating multiple allocations at once,
+   which may be useful for sparse binding.
+-# If you already have a buffer or an image created, you want to allocate memory
+   for it and then you will bind it yourself, you can use function
+   vmaAllocateMemoryForBuffer(), vmaAllocateMemoryForImage().
+   For binding you should use functions: vmaBindBufferMemory(), vmaBindImageMemory().
+-# If you want to create a buffer or an image, allocate memory for it and bind
+   them together, all in one call, you can use function vmaCreateBuffer(),
+   vmaCreateImage(). This is the easiest and recommended way to use this library.
+
+When using 3. or 4., the library internally queries Vulkan for memory types
+supported for that buffer or image (function `vkGetBufferMemoryRequirements()`)
+and uses only one of these types.
+
+If no memory type can be found that meets all the requirements, these functions
+return `VK_ERROR_FEATURE_NOT_PRESENT`.
+
+You can leave VmaAllocationCreateInfo structure completely filled with zeros.
+It means no requirements are specified for memory type.
+It is valid, although not very useful.
+
+\section choosing_memory_type_usage Usage
+
+The easiest way to specify memory requirements is to fill member
+VmaAllocationCreateInfo::usage using one of the values of enum #VmaMemoryUsage.
+It defines high level, common usage types.
+For more details, see description of this enum.
+
+For example, if you want to create a uniform buffer that will be filled using
+transfer only once or infrequently and used for rendering every frame, you can
+do it using following code:
+
+\code
+VkBufferCreateInfo bufferInfo = { VK_STRUCTURE_TYPE_BUFFER_CREATE_INFO };
+bufferInfo.size = 65536;
+bufferInfo.usage = VK_BUFFER_USAGE_UNIFORM_BUFFER_BIT | VK_BUFFER_USAGE_TRANSFER_DST_BIT;
+
+VmaAllocationCreateInfo allocInfo = {};
+allocInfo.usage = VMA_MEMORY_USAGE_GPU_ONLY;
+
+VkBuffer buffer;
+VmaAllocation allocation;
+vmaCreateBuffer(allocator, &bufferInfo, &allocInfo, &buffer, &allocation, nullptr);
+\endcode
+
+\section choosing_memory_type_required_preferred_flags Required and preferred flags
+
+You can specify more detailed requirements by filling members
+VmaAllocationCreateInfo::requiredFlags and VmaAllocationCreateInfo::preferredFlags
+with a combination of bits from enum `VkMemoryPropertyFlags`. For example,
+if you want to create a buffer that will be persistently mapped on host (so it
+must be `HOST_VISIBLE`) and preferably will also be `HOST_COHERENT` and `HOST_CACHED`,
+use following code:
+
+\code
+VmaAllocationCreateInfo allocInfo = {};
+allocInfo.requiredFlags = VK_MEMORY_PROPERTY_HOST_VISIBLE_BIT;
+allocInfo.preferredFlags = VK_MEMORY_PROPERTY_HOST_COHERENT_BIT | VK_MEMORY_PROPERTY_HOST_CACHED_BIT;
+allocInfo.flags = VMA_ALLOCATION_CREATE_MAPPED_BIT;
+
+VkBuffer buffer;
+VmaAllocation allocation;
+vmaCreateBuffer(allocator, &bufferInfo, &allocInfo, &buffer, &allocation, nullptr);
+\endcode
+
+A memory type is chosen that has all the required flags and as many preferred
+flags set as possible.
+
+If you use VmaAllocationCreateInfo::usage, it is just internally converted to
+a set of required and preferred flags.
+
+\section choosing_memory_type_explicit_memory_types Explicit memory types
+
+If you inspected memory types available on the physical device and you have
+a preference for memory types that you want to use, you can fill member
+VmaAllocationCreateInfo::memoryTypeBits. It is a bit mask, where each bit set
+means that a memory type with that index is allowed to be used for the
+allocation. Special value 0, just like `UINT32_MAX`, means there are no
+restrictions to memory type index.
+
+Please note that this member is NOT just a memory type index.
+Still you can use it to choose just one, specific memory type.
+For example, if you already determined that your buffer should be created in
+memory type 2, use following code:
+
+\code
+uint32_t memoryTypeIndex = 2;
+
+VmaAllocationCreateInfo allocInfo = {};
+allocInfo.memoryTypeBits = 1u << memoryTypeIndex;
+
+VkBuffer buffer;
+VmaAllocation allocation;
+vmaCreateBuffer(allocator, &bufferInfo, &allocInfo, &buffer, &allocation, nullptr);
+\endcode
+
+\section choosing_memory_type_custom_memory_pools Custom memory pools
+
+If you allocate from custom memory pool, all the ways of specifying memory
+requirements described above are not applicable and the aforementioned members
+of VmaAllocationCreateInfo structure are ignored. Memory type is selected
+explicitly when creating the pool and then used to make all the allocations from
+that pool. For further details, see \ref custom_memory_pools.
+
+\section choosing_memory_type_dedicated_allocations Dedicated allocations
+
+Memory for allocations is reserved out of larger block of `VkDeviceMemory`
+allocated from Vulkan internally. That's the main feature of this whole library.
+You can still request a separate memory block to be created for an allocation,
+just like you would do in a trivial solution without using any allocator.
+In that case, a buffer or image is always bound to that memory at offset 0.
+This is called a "dedicated allocation".
+You can explicitly request it by using flag #VMA_ALLOCATION_CREATE_DEDICATED_MEMORY_BIT.
+The library can also internally decide to use dedicated allocation in some cases, e.g.:
+
+- When the size of the allocation is large.
+- When [VK_KHR_dedicated_allocation](@ref vk_khr_dedicated_allocation) extension is enabled
+  and it reports that dedicated allocation is required or recommended for the resource.
+- When allocation of next big memory block fails due to not enough device memory,
+  but allocation with the exact requested size succeeds.
+
+
+\page memory_mapping Memory mapping
+
+To "map memory" in Vulkan means to obtain a CPU pointer to `VkDeviceMemory`,
+to be able to read from it or write to it in CPU code.
+Mapping is possible only of memory allocated from a memory type that has
+`VK_MEMORY_PROPERTY_HOST_VISIBLE_BIT` flag.
+Functions `vkMapMemory()`, `vkUnmapMemory()` are designed for this purpose.
+You can use them directly with memory allocated by this library,
+but it is not recommended because of following issue:
+Mapping the same `VkDeviceMemory` block multiple times is illegal - only one mapping at a time is allowed.
+This includes mapping disjoint regions. Mapping is not reference-counted internally by Vulkan.
+Because of this, Vulkan Memory Allocator provides following facilities:
+
+\section memory_mapping_mapping_functions Mapping functions
+
+The library provides following functions for mapping of a specific #VmaAllocation: vmaMapMemory(), vmaUnmapMemory().
+They are safer and more convenient to use than standard Vulkan functions.
+You can map an allocation multiple times simultaneously - mapping is reference-counted internally.
+You can also map different allocations simultaneously regardless of whether they use the same `VkDeviceMemory` block.
+The way it's implemented is that the library always maps entire memory block, not just region of the allocation.
+For further details, see description of vmaMapMemory() function.
+Example:
+
+\code
+// Having these objects initialized:
+
+struct ConstantBuffer
+{
+    ...
+};
+ConstantBuffer constantBufferData;
+
+VmaAllocator allocator;
+VkBuffer constantBuffer;
+VmaAllocation constantBufferAllocation;
+
+// You can map and fill your buffer using following code:
+
+void* mappedData;
+vmaMapMemory(allocator, constantBufferAllocation, &mappedData);
+memcpy(mappedData, &constantBufferData, sizeof(constantBufferData));
+vmaUnmapMemory(allocator, constantBufferAllocation);
+\endcode
+
+When mapping, you may see a warning from Vulkan validation layer similar to this one:
+
+<i>Mapping an image with layout VK_IMAGE_LAYOUT_DEPTH_STENCIL_ATTACHMENT_OPTIMAL can result in undefined behavior if this memory is used by the device. Only GENERAL or PREINITIALIZED should be used.</i>
+
+It happens because the library maps entire `VkDeviceMemory` block, where different
+types of images and buffers may end up together, especially on GPUs with unified memory like Intel.
+You can safely ignore it if you are sure you access only memory of the intended
+object that you wanted to map.
+
+
+\section memory_mapping_persistently_mapped_memory Persistently mapped memory
+
+Kepping your memory persistently mapped is generally OK in Vulkan.
+You don't need to unmap it before using its data on the GPU.
+The library provides a special feature designed for that:
+Allocations made with #VMA_ALLOCATION_CREATE_MAPPED_BIT flag set in
+VmaAllocationCreateInfo::flags stay mapped all the time,
+so you can just access CPU pointer to it any time
+without a need to call any "map" or "unmap" function.
+Example:
+
+\code
+VkBufferCreateInfo bufCreateInfo = { VK_STRUCTURE_TYPE_BUFFER_CREATE_INFO };
+bufCreateInfo.size = sizeof(ConstantBuffer);
+bufCreateInfo.usage = VK_BUFFER_USAGE_TRANSFER_SRC_BIT;
+
+VmaAllocationCreateInfo allocCreateInfo = {};
+allocCreateInfo.usage = VMA_MEMORY_USAGE_CPU_ONLY;
+allocCreateInfo.flags = VMA_ALLOCATION_CREATE_MAPPED_BIT;
+
+VkBuffer buf;
+VmaAllocation alloc;
+VmaAllocationInfo allocInfo;
+vmaCreateBuffer(allocator, &bufCreateInfo, &allocCreateInfo, &buf, &alloc, &allocInfo);
+
+// Buffer is already mapped. You can access its memory.
+memcpy(allocInfo.pMappedData, &constantBufferData, sizeof(constantBufferData));
+\endcode
+
+There are some exceptions though, when you should consider mapping memory only for a short period of time:
+
+- When operating system is Windows 7 or 8.x (Windows 10 is not affected because it uses WDDM2),
+  device is discrete AMD GPU,
+  and memory type is the special 256 MiB pool of `DEVICE_LOCAL + HOST_VISIBLE` memory
+  (selected when you use #VMA_MEMORY_USAGE_CPU_TO_GPU),
+  then whenever a memory block allocated from this memory type stays mapped
+  for the time of any call to `vkQueueSubmit()` or `vkQueuePresentKHR()`, this
+  block is migrated by WDDM to system RAM, which degrades performance. It doesn't
+  matter if that particular memory block is actually used by the command buffer
+  being submitted.
+- On Mac/MoltenVK there is a known bug - [Issue #175](https://github.com/KhronosGroup/MoltenVK/issues/175)
+  which requires unmapping before GPU can see updated texture.
+- Keeping many large memory blocks mapped may impact performance or stability of some debugging tools.
+
+\section memory_mapping_cache_control Cache control
+
+Memory in Vulkan doesn't need to be unmapped before using it on GPU,
+but unless a memory types has `VK_MEMORY_PROPERTY_HOST_COHERENT_BIT` flag set,
+you need to manually invalidate cache before reading of mapped pointer
+and flush cache after writing to mapped pointer.
+Vulkan provides following functions for this purpose `vkFlushMappedMemoryRanges()`,
+`vkInvalidateMappedMemoryRanges()`, but this library provides more convenient
+functions that refer to given allocation object: vmaFlushAllocation(),
+vmaInvalidateAllocation().
+
+Regions of memory specified for flush/invalidate must be aligned to
+`VkPhysicalDeviceLimits::nonCoherentAtomSize`. This is automatically ensured by the library.
+In any memory type that is `HOST_VISIBLE` but not `HOST_COHERENT`, all allocations
+within blocks are aligned to this value, so their offsets are always multiply of
+`nonCoherentAtomSize` and two different allocations never share same "line" of this size.
+
+Please note that memory allocated with #VMA_MEMORY_USAGE_CPU_ONLY is guaranteed to be `HOST_COHERENT`.
+
+Also, Windows drivers from all 3 PC GPU vendors (AMD, Intel, NVIDIA)
+currently provide `HOST_COHERENT` flag on all memory types that are
+`HOST_VISIBLE`, so on this platform you may not need to bother.
+
+\section memory_mapping_finding_if_memory_mappable Finding out if memory is mappable
+
+It may happen that your allocation ends up in memory that is `HOST_VISIBLE` (available for mapping)
+despite it wasn't explicitly requested.
+For example, application may work on integrated graphics with unified memory (like Intel) or
+allocation from video memory might have failed, so the library chose system memory as fallback.
+
+You can detect this case and map such allocation to access its memory on CPU directly,
+instead of launching a transfer operation.
+In order to do that: inspect `allocInfo.memoryType`, call vmaGetMemoryTypeProperties(),
+and look for `VK_MEMORY_PROPERTY_HOST_VISIBLE_BIT` flag in properties of that memory type.
+
+\code
+VkBufferCreateInfo bufCreateInfo = { VK_STRUCTURE_TYPE_BUFFER_CREATE_INFO };
+bufCreateInfo.size = sizeof(ConstantBuffer);
+bufCreateInfo.usage = VK_BUFFER_USAGE_UNIFORM_BUFFER_BIT | VK_BUFFER_USAGE_TRANSFER_DST_BIT;
+
+VmaAllocationCreateInfo allocCreateInfo = {};
+allocCreateInfo.usage = VMA_MEMORY_USAGE_GPU_ONLY;
+allocCreateInfo.preferredFlags = VK_MEMORY_PROPERTY_HOST_VISIBLE_BIT;
+
+VkBuffer buf;
+VmaAllocation alloc;
+VmaAllocationInfo allocInfo;
+vmaCreateBuffer(allocator, &bufCreateInfo, &allocCreateInfo, &buf, &alloc, &allocInfo);
+
+VkMemoryPropertyFlags memFlags;
+vmaGetMemoryTypeProperties(allocator, allocInfo.memoryType, &memFlags);
+if((memFlags & VK_MEMORY_PROPERTY_HOST_VISIBLE_BIT) == 0)
+{
+    // Allocation ended up in mappable memory. You can map it and access it directly.
+    void* mappedData;
+    vmaMapMemory(allocator, alloc, &mappedData);
+    memcpy(mappedData, &constantBufferData, sizeof(constantBufferData));
+    vmaUnmapMemory(allocator, alloc);
+}
+else
+{
+    // Allocation ended up in non-mappable memory.
+    // You need to create CPU-side buffer in VMA_MEMORY_USAGE_CPU_ONLY and make a transfer.
+}
+\endcode
+
+You can even use #VMA_ALLOCATION_CREATE_MAPPED_BIT flag while creating allocations
+that are not necessarily `HOST_VISIBLE` (e.g. using #VMA_MEMORY_USAGE_GPU_ONLY).
+If the allocation ends up in memory type that is `HOST_VISIBLE`, it will be persistently mapped and you can use it directly.
+If not, the flag is just ignored.
+Example:
+
+\code
+VkBufferCreateInfo bufCreateInfo = { VK_STRUCTURE_TYPE_BUFFER_CREATE_INFO };
+bufCreateInfo.size = sizeof(ConstantBuffer);
+bufCreateInfo.usage = VK_BUFFER_USAGE_UNIFORM_BUFFER_BIT | VK_BUFFER_USAGE_TRANSFER_DST_BIT;
+
+VmaAllocationCreateInfo allocCreateInfo = {};
+allocCreateInfo.usage = VMA_MEMORY_USAGE_GPU_ONLY;
+allocCreateInfo.flags = VMA_ALLOCATION_CREATE_MAPPED_BIT;
+
+VkBuffer buf;
+VmaAllocation alloc;
+VmaAllocationInfo allocInfo;
+vmaCreateBuffer(allocator, &bufCreateInfo, &allocCreateInfo, &buf, &alloc, &allocInfo);
+
+if(allocInfo.pUserData != nullptr)
+{
+    // Allocation ended up in mappable memory.
+    // It's persistently mapped. You can access it directly.
+    memcpy(allocInfo.pMappedData, &constantBufferData, sizeof(constantBufferData));
+}
+else
+{
+    // Allocation ended up in non-mappable memory.
+    // You need to create CPU-side buffer in VMA_MEMORY_USAGE_CPU_ONLY and make a transfer.
+}
+\endcode
+
+
+\page custom_memory_pools Custom memory pools
+
+A memory pool contains a number of `VkDeviceMemory` blocks.
+The library automatically creates and manages default pool for each memory type available on the device.
+Default memory pool automatically grows in size.
+Size of allocated blocks is also variable and managed automatically.
+
+You can create custom pool and allocate memory out of it.
+It can be useful if you want to:
+
+- Keep certain kind of allocations separate from others.
+- Enforce particular, fixed size of Vulkan memory blocks.
+- Limit maximum amount of Vulkan memory allocated for that pool.
+- Reserve minimum or fixed amount of Vulkan memory always preallocated for that pool.
+
+To use custom memory pools:
+
+-# Fill VmaPoolCreateInfo structure.
+-# Call vmaCreatePool() to obtain #VmaPool handle.
+-# When making an allocation, set VmaAllocationCreateInfo::pool to this handle.
+   You don't need to specify any other parameters of this structure, like `usage`.
+
+Example:
+
+\code
+// Create a pool that can have at most 2 blocks, 128 MiB each.
+VmaPoolCreateInfo poolCreateInfo = {};
+poolCreateInfo.memoryTypeIndex = ...
+poolCreateInfo.blockSize = 128ull * 1024 * 1024;
+poolCreateInfo.maxBlockCount = 2;
+
+VmaPool pool;
+vmaCreatePool(allocator, &poolCreateInfo, &pool);
+
+// Allocate a buffer out of it.
+VkBufferCreateInfo bufCreateInfo = { VK_STRUCTURE_TYPE_BUFFER_CREATE_INFO };
+bufCreateInfo.size = 1024;
+bufCreateInfo.usage = VK_BUFFER_USAGE_UNIFORM_BUFFER_BIT | VK_BUFFER_USAGE_TRANSFER_DST_BIT;
+
+VmaAllocationCreateInfo allocCreateInfo = {};
+allocCreateInfo.pool = pool;
+
+VkBuffer buf;
+VmaAllocation alloc;
+VmaAllocationInfo allocInfo;
+vmaCreateBuffer(allocator, &bufCreateInfo, &allocCreateInfo, &buf, &alloc, &allocInfo);
+\endcode
+
+You have to free all allocations made from this pool before destroying it.
+
+\code
+vmaDestroyBuffer(allocator, buf, alloc);
+vmaDestroyPool(allocator, pool);
+\endcode
+
+\section custom_memory_pools_MemTypeIndex Choosing memory type index
+
+When creating a pool, you must explicitly specify memory type index.
+To find the one suitable for your buffers or images, you can use helper functions
+vmaFindMemoryTypeIndexForBufferInfo(), vmaFindMemoryTypeIndexForImageInfo().
+You need to provide structures with example parameters of buffers or images
+that you are going to create in that pool.
+
+\code
+VkBufferCreateInfo exampleBufCreateInfo = { VK_STRUCTURE_TYPE_BUFFER_CREATE_INFO };
+exampleBufCreateInfo.size = 1024; // Whatever.
+exampleBufCreateInfo.usage = VK_BUFFER_USAGE_UNIFORM_BUFFER_BIT | VK_BUFFER_USAGE_TRANSFER_DST_BIT; // Change if needed.
+
+VmaAllocationCreateInfo allocCreateInfo = {};
+allocCreateInfo.usage = VMA_MEMORY_USAGE_GPU_ONLY; // Change if needed.
+
+uint32_t memTypeIndex;
+vmaFindMemoryTypeIndexForBufferInfo(allocator, &exampleBufCreateInfo, &allocCreateInfo, &memTypeIndex);
+
+VmaPoolCreateInfo poolCreateInfo = {};
+poolCreateInfo.memoryTypeIndex = memTypeIndex;
+// ...
+\endcode
+
+When creating buffers/images allocated in that pool, provide following parameters:
+
+- `VkBufferCreateInfo`: Prefer to pass same parameters as above.
+  Otherwise you risk creating resources in a memory type that is not suitable for them, which may result in undefined behavior.
+  Using different `VK_BUFFER_USAGE_` flags may work, but you shouldn't create images in a pool intended for buffers
+  or the other way around.
+- VmaAllocationCreateInfo: You don't need to pass same parameters. Fill only `pool` member.
+  Other members are ignored anyway.
+
+\section linear_algorithm Linear allocation algorithm
+
+Each Vulkan memory block managed by this library has accompanying metadata that
+keeps track of used and unused regions. By default, the metadata structure and
+algorithm tries to find best place for new allocations among free regions to
+optimize memory usage. This way you can allocate and free objects in any order.
+
+![Default allocation algorithm](../gfx/Linear_allocator_1_algo_default.png)
+
+Sometimes there is a need to use simpler, linear allocation algorithm. You can
+create custom pool that uses such algorithm by adding flag
+#VMA_POOL_CREATE_LINEAR_ALGORITHM_BIT to VmaPoolCreateInfo::flags while creating
+#VmaPool object. Then an alternative metadata management is used. It always
+creates new allocations after last one and doesn't reuse free regions after
+allocations freed in the middle. It results in better allocation performance and
+less memory consumed by metadata.
+
+![Linear allocation algorithm](../gfx/Linear_allocator_2_algo_linear.png)
+
+With this one flag, you can create a custom pool that can be used in many ways:
+free-at-once, stack, double stack, and ring buffer. See below for details.
+
+\subsection linear_algorithm_free_at_once Free-at-once
+
+In a pool that uses linear algorithm, you still need to free all the allocations
+individually, e.g. by using vmaFreeMemory() or vmaDestroyBuffer(). You can free
+them in any order. New allocations are always made after last one - free space
+in the middle is not reused. However, when you release all the allocation and
+the pool becomes empty, allocation starts from the beginning again. This way you
+can use linear algorithm to speed up creation of allocations that you are going
+to release all at once.
+
+![Free-at-once](../gfx/Linear_allocator_3_free_at_once.png)
+
+This mode is also available for pools created with VmaPoolCreateInfo::maxBlockCount
+value that allows multiple memory blocks.
+
+\subsection linear_algorithm_stack Stack
+
+When you free an allocation that was created last, its space can be reused.
+Thanks to this, if you always release allocations in the order opposite to their
+creation (LIFO - Last In First Out), you can achieve behavior of a stack.
+
+![Stack](../gfx/Linear_allocator_4_stack.png)
+
+This mode is also available for pools created with VmaPoolCreateInfo::maxBlockCount
+value that allows multiple memory blocks.
+
+\subsection linear_algorithm_double_stack Double stack
+
+The space reserved by a custom pool with linear algorithm may be used by two
+stacks:
+
+- First, default one, growing up from offset 0.
+- Second, "upper" one, growing down from the end towards lower offsets.
+
+To make allocation from upper stack, add flag #VMA_ALLOCATION_CREATE_UPPER_ADDRESS_BIT
+to VmaAllocationCreateInfo::flags.
+
+![Double stack](../gfx/Linear_allocator_7_double_stack.png)
+
+Double stack is available only in pools with one memory block -
+VmaPoolCreateInfo::maxBlockCount must be 1. Otherwise behavior is undefined.
+
+When the two stacks' ends meet so there is not enough space between them for a
+new allocation, such allocation fails with usual
+`VK_ERROR_OUT_OF_DEVICE_MEMORY` error.
+
+\subsection linear_algorithm_ring_buffer Ring buffer
+
+When you free some allocations from the beginning and there is not enough free space
+for a new one at the end of a pool, allocator's "cursor" wraps around to the
+beginning and starts allocation there. Thanks to this, if you always release
+allocations in the same order as you created them (FIFO - First In First Out),
+you can achieve behavior of a ring buffer / queue.
+
+![Ring buffer](../gfx/Linear_allocator_5_ring_buffer.png)
+
+Pools with linear algorithm support [lost allocations](@ref lost_allocations) when used as ring buffer.
+If there is not enough free space for a new allocation, but existing allocations
+from the front of the queue can become lost, they become lost and the allocation
+succeeds.
+
+![Ring buffer with lost allocations](../gfx/Linear_allocator_6_ring_buffer_lost.png)
+
+Ring buffer is available only in pools with one memory block -
+VmaPoolCreateInfo::maxBlockCount must be 1. Otherwise behavior is undefined.
+
+\section buddy_algorithm Buddy allocation algorithm
+
+There is another allocation algorithm that can be used with custom pools, called
+"buddy". Its internal data structure is based on a tree of blocks, each having
+size that is a power of two and a half of its parent's size. When you want to
+allocate memory of certain size, a free node in the tree is located. If it's too
+large, it is recursively split into two halves (called "buddies"). However, if
+requested allocation size is not a power of two, the size of a tree node is
+aligned up to the nearest power of two and the remaining space is wasted. When
+two buddy nodes become free, they are merged back into one larger node.
+
+![Buddy allocator](../gfx/Buddy_allocator.png)
+
+The advantage of buddy allocation algorithm over default algorithm is faster
+allocation and deallocation, as well as smaller external fragmentation. The
+disadvantage is more wasted space (internal fragmentation).
+
+For more information, please read ["Buddy memory allocation" on Wikipedia](https://en.wikipedia.org/wiki/Buddy_memory_allocation)
+or other sources that describe this concept in general.
+
+To use buddy allocation algorithm with a custom pool, add flag
+#VMA_POOL_CREATE_BUDDY_ALGORITHM_BIT to VmaPoolCreateInfo::flags while creating
+#VmaPool object.
+
+Several limitations apply to pools that use buddy algorithm:
+
+- It is recommended to use VmaPoolCreateInfo::blockSize that is a power of two.
+  Otherwise, only largest power of two smaller than the size is used for
+  allocations. The remaining space always stays unused.
+- [Margins](@ref debugging_memory_usage_margins) and
+  [corruption detection](@ref debugging_memory_usage_corruption_detection)
+  don't work in such pools.
+- [Lost allocations](@ref lost_allocations) don't work in such pools. You can
+  use them, but they never become lost. Support may be added in the future.
+- [Defragmentation](@ref defragmentation) doesn't work with allocations made from
+  such pool.
+
+\page defragmentation Defragmentation
+
+Interleaved allocations and deallocations of many objects of varying size can
+cause fragmentation over time, which can lead to a situation where the library is unable
+to find a continuous range of free memory for a new allocation despite there is
+enough free space, just scattered across many small free ranges between existing
+allocations.
+
+To mitigate this problem, you can use defragmentation feature:
+structure #VmaDefragmentationInfo2, function vmaDefragmentationBegin(), vmaDefragmentationEnd().
+Given set of allocations,
+this function can move them to compact used memory, ensure more continuous free
+space and possibly also free some `VkDeviceMemory` blocks.
+
+What the defragmentation does is:
+
+- Updates #VmaAllocation objects to point to new `VkDeviceMemory` and offset.
+  After allocation has been moved, its VmaAllocationInfo::deviceMemory and/or
+  VmaAllocationInfo::offset changes. You must query them again using
+  vmaGetAllocationInfo() if you need them.
+- Moves actual data in memory.
+
+What it doesn't do, so you need to do it yourself:
+
+- Recreate buffers and images that were bound to allocations that were defragmented and
+  bind them with their new places in memory.
+  You must use `vkDestroyBuffer()`, `vkDestroyImage()`,
+  `vkCreateBuffer()`, `vkCreateImage()` for that purpose and NOT vmaDestroyBuffer(),
+  vmaDestroyImage(), vmaCreateBuffer(), vmaCreateImage(), because you don't need to
+  destroy or create allocation objects!
+- Recreate views and update descriptors that point to these buffers and images.
+
+\section defragmentation_cpu Defragmenting CPU memory
+
+Following example demonstrates how you can run defragmentation on CPU.
+Only allocations created in memory types that are `HOST_VISIBLE` can be defragmented.
+Others are ignored.
+
+The way it works is:
+
+- It temporarily maps entire memory blocks when necessary.
+- It moves data using `memmove()` function.
+
+\code
+// Given following variables already initialized:
+VkDevice device;
+VmaAllocator allocator;
+std::vector<VkBuffer> buffers;
+std::vector<VmaAllocation> allocations;
+
+
+const uint32_t allocCount = (uint32_t)allocations.size();
+std::vector<VkBool32> allocationsChanged(allocCount);
+
+VmaDefragmentationInfo2 defragInfo = {};
+defragInfo.allocationCount = allocCount;
+defragInfo.pAllocations = allocations.data();
+defragInfo.pAllocationsChanged = allocationsChanged.data();
+defragInfo.maxCpuBytesToMove = VK_WHOLE_SIZE; // No limit.
+defragInfo.maxCpuAllocationsToMove = UINT32_MAX; // No limit.
+
+VmaDefragmentationContext defragCtx;
+vmaDefragmentationBegin(allocator, &defragInfo, nullptr, &defragCtx);
+vmaDefragmentationEnd(allocator, defragCtx);
+
+for(uint32_t i = 0; i < allocCount; ++i)
+{
+    if(allocationsChanged[i])
+    {
+	// Destroy buffer that is immutably bound to memory region which is no longer valid.
+	vkDestroyBuffer(device, buffers[i], nullptr);
+
+	// Create new buffer with same parameters.
+	VkBufferCreateInfo bufferInfo = ...;
+	vkCreateBuffer(device, &bufferInfo, nullptr, &buffers[i]);
+
+	// You can make dummy call to vkGetBufferMemoryRequirements here to silence validation layer warning.
+
+	// Bind new buffer to new memory region. Data contained in it is already moved.
+	VmaAllocationInfo allocInfo;
+	vmaGetAllocationInfo(allocator, allocations[i], &allocInfo);
+	vkBindBufferMemory(device, buffers[i], allocInfo.deviceMemory, allocInfo.offset);
+    }
+}
+\endcode
+
+Setting VmaDefragmentationInfo2::pAllocationsChanged is optional.
+This output array tells whether particular allocation in VmaDefragmentationInfo2::pAllocations at the same index
+has been modified during defragmentation.
+You can pass null, but you then need to query every allocation passed to defragmentation
+for new parameters using vmaGetAllocationInfo() if you might need to recreate and rebind a buffer or image associated with it.
+
+If you use [Custom memory pools](@ref choosing_memory_type_custom_memory_pools),
+you can fill VmaDefragmentationInfo2::poolCount and VmaDefragmentationInfo2::pPools
+instead of VmaDefragmentationInfo2::allocationCount and VmaDefragmentationInfo2::pAllocations
+to defragment all allocations in given pools.
+You cannot use VmaDefragmentationInfo2::pAllocationsChanged in that case.
+You can also combine both methods.
+
+\section defragmentation_gpu Defragmenting GPU memory
+
+It is also possible to defragment allocations created in memory types that are not `HOST_VISIBLE`.
+To do that, you need to pass a command buffer that meets requirements as described in
+VmaDefragmentationInfo2::commandBuffer. The way it works is:
+
+- It creates temporary buffers and binds them to entire memory blocks when necessary.
+- It issues `vkCmdCopyBuffer()` to passed command buffer.
+
+Example:
+
+\code
+// Given following variables already initialized:
+VkDevice device;
+VmaAllocator allocator;
+VkCommandBuffer commandBuffer;
+std::vector<VkBuffer> buffers;
+std::vector<VmaAllocation> allocations;
+
+
+const uint32_t allocCount = (uint32_t)allocations.size();
+std::vector<VkBool32> allocationsChanged(allocCount);
+
+VkCommandBufferBeginInfo cmdBufBeginInfo = ...;
+vkBeginCommandBuffer(commandBuffer, &cmdBufBeginInfo);
+
+VmaDefragmentationInfo2 defragInfo = {};
+defragInfo.allocationCount = allocCount;
+defragInfo.pAllocations = allocations.data();
+defragInfo.pAllocationsChanged = allocationsChanged.data();
+defragInfo.maxGpuBytesToMove = VK_WHOLE_SIZE; // Notice it's "GPU" this time.
+defragInfo.maxGpuAllocationsToMove = UINT32_MAX; // Notice it's "GPU" this time.
+defragInfo.commandBuffer = commandBuffer;
+
+VmaDefragmentationContext defragCtx;
+vmaDefragmentationBegin(allocator, &defragInfo, nullptr, &defragCtx);
+
+vkEndCommandBuffer(commandBuffer);
+
+// Submit commandBuffer.
+// Wait for a fence that ensures commandBuffer execution finished.
+
+vmaDefragmentationEnd(allocator, defragCtx);
+
+for(uint32_t i = 0; i < allocCount; ++i)
+{
+    if(allocationsChanged[i])
+    {
+	// Destroy buffer that is immutably bound to memory region which is no longer valid.
+	vkDestroyBuffer(device, buffers[i], nullptr);
+
+	// Create new buffer with same parameters.
+	VkBufferCreateInfo bufferInfo = ...;
+	vkCreateBuffer(device, &bufferInfo, nullptr, &buffers[i]);
+
+	// You can make dummy call to vkGetBufferMemoryRequirements here to silence validation layer warning.
+
+	// Bind new buffer to new memory region. Data contained in it is already moved.
+	VmaAllocationInfo allocInfo;
+	vmaGetAllocationInfo(allocator, allocations[i], &allocInfo);
+	vkBindBufferMemory(device, buffers[i], allocInfo.deviceMemory, allocInfo.offset);
+    }
+}
+\endcode
+
+You can combine these two methods by specifying non-zero `maxGpu*` as well as `maxCpu*` parameters.
+The library automatically chooses best method to defragment each memory pool.
+
+You may try not to block your entire program to wait until defragmentation finishes,
+but do it in the background, as long as you carefully fullfill requirements described
+in function vmaDefragmentationBegin().
+
+\section defragmentation_additional_notes Additional notes
+
+It is only legal to defragment allocations bound to:
+
+- buffers
+- images created with `VK_IMAGE_CREATE_ALIAS_BIT`, `VK_IMAGE_TILING_LINEAR`, and
+  being currently in `VK_IMAGE_LAYOUT_GENERAL` or `VK_IMAGE_LAYOUT_PREINITIALIZED`.
+
+Defragmentation of images created with `VK_IMAGE_TILING_OPTIMAL` or in any other
+layout may give undefined results.
+
+If you defragment allocations bound to images, new images to be bound to new
+memory region after defragmentation should be created with `VK_IMAGE_LAYOUT_PREINITIALIZED`
+and then transitioned to their original layout from before defragmentation if
+needed using an image memory barrier.
+
+While using defragmentation, you may experience validation layer warnings, which you just need to ignore.
+See [Validation layer warnings](@ref general_considerations_validation_layer_warnings).
+
+Please don't expect memory to be fully compacted after defragmentation.
+Algorithms inside are based on some heuristics that try to maximize number of Vulkan
+memory blocks to make totally empty to release them, as well as to maximimze continuous
+empty space inside remaining blocks, while minimizing the number and size of allocations that
+need to be moved. Some fragmentation may still remain - this is normal.
+
+\section defragmentation_custom_algorithm Writing custom defragmentation algorithm
+
+If you want to implement your own, custom defragmentation algorithm,
+there is infrastructure prepared for that,
+but it is not exposed through the library API - you need to hack its source code.
+Here are steps needed to do this:
+
+-# Main thing you need to do is to define your own class derived from base abstract
+   class `VmaDefragmentationAlgorithm` and implement your version of its pure virtual methods.
+   See definition and comments of this class for details.
+-# Your code needs to interact with device memory block metadata.
+   If you need more access to its data than it's provided by its public interface,
+   declare your new class as a friend class e.g. in class `VmaBlockMetadata_Generic`.
+-# If you want to create a flag that would enable your algorithm or pass some additional
+   flags to configure it, add them to `VmaDefragmentationFlagBits` and use them in
+   VmaDefragmentationInfo2::flags.
+-# Modify function `VmaBlockVectorDefragmentationContext::Begin` to create object
+   of your new class whenever needed.
+
+
+\page lost_allocations Lost allocations
+
+If your game oversubscribes video memory, if may work OK in previous-generation
+graphics APIs (DirectX 9, 10, 11, OpenGL) because resources are automatically
+paged to system RAM. In Vulkan you can't do it because when you run out of
+memory, an allocation just fails. If you have more data (e.g. textures) that can
+fit into VRAM and you don't need it all at once, you may want to upload them to
+GPU on demand and "push out" ones that are not used for a long time to make room
+for the new ones, effectively using VRAM (or a cartain memory pool) as a form of
+cache. Vulkan Memory Allocator can help you with that by supporting a concept of
+"lost allocations".
+
+To create an allocation that can become lost, include #VMA_ALLOCATION_CREATE_CAN_BECOME_LOST_BIT
+flag in VmaAllocationCreateInfo::flags. Before using a buffer or image bound to
+such allocation in every new frame, you need to query it if it's not lost.
+To check it, call vmaTouchAllocation().
+If the allocation is lost, you should not use it or buffer/image bound to it.
+You mustn't forget to destroy this allocation and this buffer/image.
+vmaGetAllocationInfo() can also be used for checking status of the allocation.
+Allocation is lost when returned VmaAllocationInfo::deviceMemory == `VK_NULL_HANDLE`.
+
+To create an allocation that can make some other allocations lost to make room
+for it, use #VMA_ALLOCATION_CREATE_CAN_MAKE_OTHER_LOST_BIT flag. You will
+usually use both flags #VMA_ALLOCATION_CREATE_CAN_MAKE_OTHER_LOST_BIT and
+#VMA_ALLOCATION_CREATE_CAN_BECOME_LOST_BIT at the same time.
+
+Warning! Current implementation uses quite naive, brute force algorithm,
+which can make allocation calls that use #VMA_ALLOCATION_CREATE_CAN_MAKE_OTHER_LOST_BIT
+flag quite slow. A new, more optimal algorithm and data structure to speed this
+up is planned for the future.
+
+<b>Q: When interleaving creation of new allocations with usage of existing ones,
+how do you make sure that an allocation won't become lost while it's used in the
+current frame?</b>
+
+It is ensured because vmaTouchAllocation() / vmaGetAllocationInfo() not only returns allocation
+status/parameters and checks whether it's not lost, but when it's not, it also
+atomically marks it as used in the current frame, which makes it impossible to
+become lost in that frame. It uses lockless algorithm, so it works fast and
+doesn't involve locking any internal mutex.
+
+<b>Q: What if my allocation may still be in use by the GPU when it's rendering a
+previous frame while I already submit new frame on the CPU?</b>
+
+You can make sure that allocations "touched" by vmaTouchAllocation() / vmaGetAllocationInfo() will not
+become lost for a number of additional frames back from the current one by
+specifying this number as VmaAllocatorCreateInfo::frameInUseCount (for default
+memory pool) and VmaPoolCreateInfo::frameInUseCount (for custom pool).
+
+<b>Q: How do you inform the library when new frame starts?</b>
+
+You need to call function vmaSetCurrentFrameIndex().
+
+Example code:
+
+\code
+struct MyBuffer
+{
+    VkBuffer m_Buf = nullptr;
+    VmaAllocation m_Alloc = nullptr;
+
+    // Called when the buffer is really needed in the current frame.
+    void EnsureBuffer();
+};
+
+void MyBuffer::EnsureBuffer()
+{
+    // Buffer has been created.
+    if(m_Buf != VK_NULL_HANDLE)
+    {
+	// Check if its allocation is not lost + mark it as used in current frame.
+	if(vmaTouchAllocation(allocator, m_Alloc))
+	{
+	    // It's all OK - safe to use m_Buf.
+	    return;
+	}
+    }
+
+    // Buffer not yet exists or lost - destroy and recreate it.
+
+    vmaDestroyBuffer(allocator, m_Buf, m_Alloc);
+
+    VkBufferCreateInfo bufCreateInfo = { VK_STRUCTURE_TYPE_BUFFER_CREATE_INFO };
+    bufCreateInfo.size = 1024;
+    bufCreateInfo.usage = VK_BUFFER_USAGE_UNIFORM_BUFFER_BIT | VK_BUFFER_USAGE_TRANSFER_DST_BIT;
+
+    VmaAllocationCreateInfo allocCreateInfo = {};
+    allocCreateInfo.usage = VMA_MEMORY_USAGE_GPU_ONLY;
+    allocCreateInfo.flags = VMA_ALLOCATION_CREATE_CAN_BECOME_LOST_BIT |
+	VMA_ALLOCATION_CREATE_CAN_MAKE_OTHER_LOST_BIT;
+
+    vmaCreateBuffer(allocator, &bufCreateInfo, &allocCreateInfo, &m_Buf, &m_Alloc, nullptr);
+}
+\endcode
+
+When using lost allocations, you may see some Vulkan validation layer warnings
+about overlapping regions of memory bound to different kinds of buffers and
+images. This is still valid as long as you implement proper handling of lost
+allocations (like in the example above) and don't use them.
+
+You can create an allocation that is already in lost state from the beginning using function
+vmaCreateLostAllocation(). It may be useful if you need a "dummy" allocation that is not null.
+
+You can call function vmaMakePoolAllocationsLost() to set all eligible allocations
+in a specified custom pool to lost state.
+Allocations that have been "touched" in current frame or VmaPoolCreateInfo::frameInUseCount frames back
+cannot become lost.
+
+<b>Q: Can I touch allocation that cannot become lost?</b>
+
+Yes, although it has no visible effect.
+Calls to vmaGetAllocationInfo() and vmaTouchAllocation() update last use frame index
+also for allocations that cannot become lost, but the only way to observe it is to dump
+internal allocator state using vmaBuildStatsString().
+You can use this feature for debugging purposes to explicitly mark allocations that you use
+in current frame and then analyze JSON dump to see for how long each allocation stays unused.
+
+
+\page statistics Statistics
+
+This library contains functions that return information about its internal state,
+especially the amount of memory allocated from Vulkan.
+Please keep in mind that these functions need to traverse all internal data structures
+to gather these information, so they may be quite time-consuming.
+Don't call them too often.
+
+\section statistics_numeric_statistics Numeric statistics
+
+You can query for overall statistics of the allocator using function vmaCalculateStats().
+Information are returned using structure #VmaStats.
+It contains #VmaStatInfo - number of allocated blocks, number of allocations
+(occupied ranges in these blocks), number of unused (free) ranges in these blocks,
+number of bytes used and unused (but still allocated from Vulkan) and other information.
+They are summed across memory heaps, memory types and total for whole allocator.
+
+You can query for statistics of a custom pool using function vmaGetPoolStats().
+Information are returned using structure #VmaPoolStats.
+
+You can query for information about specific allocation using function vmaGetAllocationInfo().
+It fill structure #VmaAllocationInfo.
+
+\section statistics_json_dump JSON dump
+
+You can dump internal state of the allocator to a string in JSON format using function vmaBuildStatsString().
+The result is guaranteed to be correct JSON.
+It uses ANSI encoding.
+Any strings provided by user (see [Allocation names](@ref allocation_names))
+are copied as-is and properly escaped for JSON, so if they use UTF-8, ISO-8859-2 or any other encoding,
+this JSON string can be treated as using this encoding.
+It must be freed using function vmaFreeStatsString().
+
+The format of this JSON string is not part of official documentation of the library,
+but it will not change in backward-incompatible way without increasing library major version number
+and appropriate mention in changelog.
+
+The JSON string contains all the data that can be obtained using vmaCalculateStats().
+It can also contain detailed map of allocated memory blocks and their regions -
+free and occupied by allocations.
+This allows e.g. to visualize the memory or assess fragmentation.
+
+
+\page allocation_annotation Allocation names and user data
+
+\section allocation_user_data Allocation user data
+
+You can annotate allocations with your own information, e.g. for debugging purposes.
+To do that, fill VmaAllocationCreateInfo::pUserData field when creating
+an allocation. It's an opaque `void*` pointer. You can use it e.g. as a pointer,
+some handle, index, key, ordinal number or any other value that would associate
+the allocation with your custom metadata.
+
+\code
+VkBufferCreateInfo bufferInfo = { VK_STRUCTURE_TYPE_BUFFER_CREATE_INFO };
+// Fill bufferInfo...
+
+MyBufferMetadata* pMetadata = CreateBufferMetadata();
+
+VmaAllocationCreateInfo allocCreateInfo = {};
+allocCreateInfo.usage = VMA_MEMORY_USAGE_GPU_ONLY;
+allocCreateInfo.pUserData = pMetadata;
+
+VkBuffer buffer;
+VmaAllocation allocation;
+vmaCreateBuffer(allocator, &bufferInfo, &allocCreateInfo, &buffer, &allocation, nullptr);
+\endcode
+
+The pointer may be later retrieved as VmaAllocationInfo::pUserData:
+
+\code
+VmaAllocationInfo allocInfo;
+vmaGetAllocationInfo(allocator, allocation, &allocInfo);
+MyBufferMetadata* pMetadata = (MyBufferMetadata*)allocInfo.pUserData;
+\endcode
+
+It can also be changed using function vmaSetAllocationUserData().
+
+Values of (non-zero) allocations' `pUserData` are printed in JSON report created by
+vmaBuildStatsString(), in hexadecimal form.
+
+\section allocation_names Allocation names
+
+There is alternative mode available where `pUserData` pointer is used to point to
+a null-terminated string, giving a name to the allocation. To use this mode,
+set #VMA_ALLOCATION_CREATE_USER_DATA_COPY_STRING_BIT flag in VmaAllocationCreateInfo::flags.
+Then `pUserData` passed as VmaAllocationCreateInfo::pUserData or argument to
+vmaSetAllocationUserData() must be either null or pointer to a null-terminated string.
+The library creates internal copy of the string, so the pointer you pass doesn't need
+to be valid for whole lifetime of the allocation. You can free it after the call.
+
+\code
+VkImageCreateInfo imageInfo = { VK_STRUCTURE_TYPE_IMAGE_CREATE_INFO };
+// Fill imageInfo...
+
+std::string imageName = "Texture: ";
+imageName += fileName;
+
+VmaAllocationCreateInfo allocCreateInfo = {};
+allocCreateInfo.usage = VMA_MEMORY_USAGE_GPU_ONLY;
+allocCreateInfo.flags = VMA_ALLOCATION_CREATE_USER_DATA_COPY_STRING_BIT;
+allocCreateInfo.pUserData = imageName.c_str();
+
+VkImage image;
+VmaAllocation allocation;
+vmaCreateImage(allocator, &imageInfo, &allocCreateInfo, &image, &allocation, nullptr);
+\endcode
+
+The value of `pUserData` pointer of the allocation will be different than the one
+you passed when setting allocation's name - pointing to a buffer managed
+internally that holds copy of the string.
+
+\code
+VmaAllocationInfo allocInfo;
+vmaGetAllocationInfo(allocator, allocation, &allocInfo);
+const char* imageName = (const char*)allocInfo.pUserData;
+printf("Image name: %s\n", imageName);
+\endcode
+
+That string is also printed in JSON report created by vmaBuildStatsString().
+
+
+\page debugging_memory_usage Debugging incorrect memory usage
+
+If you suspect a bug with memory usage, like usage of uninitialized memory or
+memory being overwritten out of bounds of an allocation,
+you can use debug features of this library to verify this.
+
+\section debugging_memory_usage_initialization Memory initialization
+
+If you experience a bug with incorrect and nondeterministic data in your program and you suspect uninitialized memory to be used,
+you can enable automatic memory initialization to verify this.
+To do it, define macro `VMA_DEBUG_INITIALIZE_ALLOCATIONS` to 1.
+
+\code
+#define VMA_DEBUG_INITIALIZE_ALLOCATIONS 1
+#include "vk_mem_alloc.h"
+\endcode
+
+It makes memory of all new allocations initialized to bit pattern `0xDCDCDCDC`.
+Before an allocation is destroyed, its memory is filled with bit pattern `0xEFEFEFEF`.
+Memory is automatically mapped and unmapped if necessary.
+
+If you find these values while debugging your program, good chances are that you incorrectly
+read Vulkan memory that is allocated but not initialized, or already freed, respectively.
+
+Memory initialization works only with memory types that are `HOST_VISIBLE`.
+It works also with dedicated allocations.
+It doesn't work with allocations created with #VMA_ALLOCATION_CREATE_CAN_BECOME_LOST_BIT flag,
+as they cannot be mapped.
+
+\section debugging_memory_usage_margins Margins
+
+By default, allocations are laid out in memory blocks next to each other if possible
+(considering required alignment, `bufferImageGranularity`, and `nonCoherentAtomSize`).
+
+![Allocations without margin](../gfx/Margins_1.png)
+
+Define macro `VMA_DEBUG_MARGIN` to some non-zero value (e.g. 16) to enforce specified
+number of bytes as a margin before and after every allocation.
+
+\code
+#define VMA_DEBUG_MARGIN 16
+#include "vk_mem_alloc.h"
+\endcode
+
+![Allocations with margin](../gfx/Margins_2.png)
+
+If your bug goes away after enabling margins, it means it may be caused by memory
+being overwritten outside of allocation boundaries. It is not 100% certain though.
+Change in application behavior may also be caused by different order and distribution
+of allocations across memory blocks after margins are applied.
+
+The margin is applied also before first and after last allocation in a block.
+It may occur only once between two adjacent allocations.
+
+Margins work with all types of memory.
+
+Margin is applied only to allocations made out of memory blocks and not to dedicated
+allocations, which have their own memory block of specific size.
+It is thus not applied to allocations made using #VMA_ALLOCATION_CREATE_DEDICATED_MEMORY_BIT flag
+or those automatically decided to put into dedicated allocations, e.g. due to its
+large size or recommended by VK_KHR_dedicated_allocation extension.
+Margins are also not active in custom pools created with #VMA_POOL_CREATE_BUDDY_ALGORITHM_BIT flag.
+
+Margins appear in [JSON dump](@ref statistics_json_dump) as part of free space.
+
+Note that enabling margins increases memory usage and fragmentation.
+
+\section debugging_memory_usage_corruption_detection Corruption detection
+
+You can additionally define macro `VMA_DEBUG_DETECT_CORRUPTION` to 1 to enable validation
+of contents of the margins.
+
+\code
+#define VMA_DEBUG_MARGIN 16
+#define VMA_DEBUG_DETECT_CORRUPTION 1
+#include "vk_mem_alloc.h"
+\endcode
+
+When this feature is enabled, number of bytes specified as `VMA_DEBUG_MARGIN`
+(it must be multiply of 4) before and after every allocation is filled with a magic number.
+This idea is also know as "canary".
+Memory is automatically mapped and unmapped if necessary.
+
+This number is validated automatically when the allocation is destroyed.
+If it's not equal to the expected value, `VMA_ASSERT()` is executed.
+It clearly means that either CPU or GPU overwritten the memory outside of boundaries of the allocation,
+which indicates a serious bug.
+
+You can also explicitly request checking margins of all allocations in all memory blocks
+that belong to specified memory types by using function vmaCheckCorruption(),
+or in memory blocks that belong to specified custom pool, by using function
+vmaCheckPoolCorruption().
+
+Margin validation (corruption detection) works only for memory types that are
+`HOST_VISIBLE` and `HOST_COHERENT`.
+
+
+\page record_and_replay Record and replay
+
+\section record_and_replay_introduction Introduction
+
+While using the library, sequence of calls to its functions together with their
+parameters can be recorded to a file and later replayed using standalone player
+application. It can be useful to:
+
+- Test correctness - check if same sequence of calls will not cause crash or
+  failures on a target platform.
+- Gather statistics - see number of allocations, peak memory usage, number of
+  calls etc.
+- Benchmark performance - see how much time it takes to replay the whole
+  sequence.
+
+\section record_and_replay_usage Usage
+
+<b>To record sequence of calls to a file:</b> Fill in
+VmaAllocatorCreateInfo::pRecordSettings member while creating #VmaAllocator
+object. File is opened and written during whole lifetime of the allocator.
+
+<b>To replay file:</b> Use VmaReplay - standalone command-line program.
+Precompiled binary can be found in "bin" directory.
+Its source can be found in "src/VmaReplay" directory.
+Its project is generated by Premake.
+Command line syntax is printed when the program is launched without parameters.
+Basic usage:
+
+    VmaReplay.exe MyRecording.csv
+
+<b>Documentation of file format</b> can be found in file: "docs/Recording file format.md".
+It's a human-readable, text file in CSV format (Comma Separated Values).
+
+\section record_and_replay_additional_considerations Additional considerations
+
+- Replaying file that was recorded on a different GPU (with different parameters
+  like `bufferImageGranularity`, `nonCoherentAtomSize`, and especially different
+  set of memory heaps and types) may give different performance and memory usage
+  results, as well as issue some warnings and errors.
+- Current implementation of recording in VMA, as well as VmaReplay application, is
+  coded and tested only on Windows. Inclusion of recording code is driven by
+  `VMA_RECORDING_ENABLED` macro. Support for other platforms should be easy to
+  add. Contributions are welcomed.
+- Currently calls to vmaDefragment() function are not recorded.

+\section usage_patterns_simple Simple patterns
+
+\subsection usage_patterns_simple_render_targets Render targets
+
+<b>When:</b>
+Any resources that you frequently write and read on GPU,
+e.g. images used as color attachments (aka "render targets"), depth-stencil attachments,
+images/buffers used as storage image/buffer (aka "Unordered Access View (UAV)").
+
+<b>What to do:</b>
+Create them in video memory that is fastest to access from GPU using
+#VMA_MEMORY_USAGE_GPU_ONLY.
+
+Consider using [VK_KHR_dedicated_allocation](@ref vk_khr_dedicated_allocation) extension
+and/or manually creating them as dedicated allocations using #VMA_ALLOCATION_CREATE_DEDICATED_MEMORY_BIT,
+especially if they are large or if you plan to destroy and recreate them e.g. when
+display resolution changes.
+Prefer to create such resources first and all other GPU resources (like textures and vertex buffers) later.
+
+\subsection usage_patterns_simple_immutable_resources Immutable resources
+
+<b>When:</b>
+Any resources that you fill on CPU only once (aka "immutable") or infrequently
+and then read frequently on GPU,
+e.g. textures, vertex and index buffers, constant buffers that don't change often.
+
+<b>What to do:</b>
+Create them in video memory that is fastest to access from GPU using
+#VMA_MEMORY_USAGE_GPU_ONLY.
+
+To initialize content of such resource, create a CPU-side (aka "staging") copy of it
+in system memory - #VMA_MEMORY_USAGE_CPU_ONLY, map it, fill it,
+and submit a transfer from it to the GPU resource.
+You can keep the staging copy if you need it for another upload transfer in the future.
+If you don't, you can destroy it or reuse this buffer for uploading different resource
+after the transfer finishes.
+
+Prefer to create just buffers in system memory rather than images, even for uploading textures.
+Use `vkCmdCopyBufferToImage()`.
+Dont use images with `VK_IMAGE_TILING_LINEAR`.
+
+\subsection usage_patterns_dynamic_resources Dynamic resources
+
+<b>When:</b>
+Any resources that change frequently (aka "dynamic"), e.g. every frame or every draw call,
+written on CPU, read on GPU.
+
+<b>What to do:</b>
+Create them using #VMA_MEMORY_USAGE_CPU_TO_GPU.
+You can map it and write to it directly on CPU, as well as read from it on GPU.
+
+This is a more complex situation. Different solutions are possible,
+and the best one depends on specific GPU type, but you can use this simple approach for the start.
+Prefer to write to such resource sequentially (e.g. using `memcpy`).
+Don't perform random access or any reads from it on CPU, as it may be very slow.
+
+\subsection usage_patterns_readback Readback
+
+<b>When:</b>
+Resources that contain data written by GPU that you want to read back on CPU,
+e.g. results of some computations.
+
+<b>What to do:</b>
+Create them using #VMA_MEMORY_USAGE_GPU_TO_CPU.
+You can write to them directly on GPU, as well as map and read them on CPU.
+
+\section usage_patterns_advanced Advanced patterns
+
+\subsection usage_patterns_integrated_graphics Detecting integrated graphics
+
+You can support integrated graphics (like Intel HD Graphics, AMD APU) better
+by detecting it in Vulkan.
+To do it, call `vkGetPhysicalDeviceProperties()`, inspect
+`VkPhysicalDeviceProperties::deviceType` and look for `VK_PHYSICAL_DEVICE_TYPE_INTEGRATED_GPU`.
+When you find it, you can assume that memory is unified and all memory types are comparably fast
+to access from GPU, regardless of `VK_MEMORY_PROPERTY_DEVICE_LOCAL_BIT`.
+
+You can then sum up sizes of all available memory heaps and treat them as useful for
+your GPU resources, instead of only `DEVICE_LOCAL` ones.
+You can also prefer to create your resources in memory types that are `HOST_VISIBLE` to map them
+directly instead of submitting explicit transfer (see below).
+
+\subsection usage_patterns_direct_vs_transfer Direct access versus transfer
+
+For resources that you frequently write on CPU and read on GPU, many solutions are possible:
+
+-# Create one copy in video memory using #VMA_MEMORY_USAGE_GPU_ONLY,
+   second copy in system memory using #VMA_MEMORY_USAGE_CPU_ONLY and submit explicit tranfer each time.
+-# Create just single copy using #VMA_MEMORY_USAGE_CPU_TO_GPU, map it and fill it on CPU,
+   read it directly on GPU.
+-# Create just single copy using #VMA_MEMORY_USAGE_CPU_ONLY, map it and fill it on CPU,
+   read it directly on GPU.
+
+Which solution is the most efficient depends on your resource and especially on the GPU.
+It is best to measure it and then make the decision.
+Some general recommendations:
+
+- On integrated graphics use (2) or (3) to avoid unnecesary time and memory overhead
+  related to using a second copy and making transfer.
+- For small resources (e.g. constant buffers) use (2).
+  Discrete AMD cards have special 256 MiB pool of video memory that is directly mappable.
+  Even if the resource ends up in system memory, its data may be cached on GPU after first
+  fetch over PCIe bus.
+- For larger resources (e.g. textures), decide between (1) and (2).
+  You may want to differentiate NVIDIA and AMD, e.g. by looking for memory type that is
+  both `DEVICE_LOCAL` and `HOST_VISIBLE`. When you find it, use (2), otherwise use (1).
+
+Similarly, for resources that you frequently write on GPU and read on CPU, multiple
+solutions are possible:
+
+-# Create one copy in video memory using #VMA_MEMORY_USAGE_GPU_ONLY,
+   second copy in system memory using #VMA_MEMORY_USAGE_GPU_TO_CPU and submit explicit tranfer each time.
+-# Create just single copy using #VMA_MEMORY_USAGE_GPU_TO_CPU, write to it directly on GPU,
+   map it and read it on CPU.
+
+You should take some measurements to decide which option is faster in case of your specific
+resource.
+
+If you don't want to specialize your code for specific types of GPUs, you can still make
+an simple optimization for cases when your resource ends up in mappable memory to use it
+directly in this case instead of creating CPU-side staging copy.
+For details see [Finding out if memory is mappable](@ref memory_mapping_finding_if_memory_mappable).
+
+
+\page configuration Configuration
+
+Please check "CONFIGURATION SECTION" in the code to find macros that you can define
+before each include of this file or change directly in this file to provide
+your own implementation of basic facilities like assert, `min()` and `max()` functions,
+mutex, atomic etc.
+The library uses its own implementation of containers by default, but you can switch to using
+STL containers instead.
+
+\section config_Vulkan_functions Pointers to Vulkan functions
+
+The library uses Vulkan functions straight from the `vulkan.h` header by default.
+If you want to provide your own pointers to these functions, e.g. fetched using
+`vkGetInstanceProcAddr()` and `vkGetDeviceProcAddr()`:
+
+-# Define `VMA_STATIC_VULKAN_FUNCTIONS 0`.
+-# Provide valid pointers through VmaAllocatorCreateInfo::pVulkanFunctions.
+
+\section custom_memory_allocator Custom host memory allocator
+
+If you use custom allocator for CPU memory rather than default operator `new`
+and `delete` from C++, you can make this library using your allocator as well
+by filling optional member VmaAllocatorCreateInfo::pAllocationCallbacks. These
+functions will be passed to Vulkan, as well as used by the library itself to
+make any CPU-side allocations.
+
+\section allocation_callbacks Device memory allocation callbacks
+
+The library makes calls to `vkAllocateMemory()` and `vkFreeMemory()` internally.
+You can setup callbacks to be informed about these calls, e.g. for the purpose
+of gathering some statistics. To do it, fill optional member
+VmaAllocatorCreateInfo::pDeviceMemoryCallbacks.
+
+\section heap_memory_limit Device heap memory limit
+
+When device memory of certain heap runs out of free space, new allocations may
+fail (returning error code) or they may succeed, silently pushing some existing
+memory blocks from GPU VRAM to system RAM (which degrades performance). This
+behavior is implementation-dependant - it depends on GPU vendor and graphics
+driver.
+
+On AMD cards it can be controlled while creating Vulkan device object by using
+VK_AMD_memory_allocation_behavior extension, if available.
+
+Alternatively, if you want to test how your program behaves with limited amount of Vulkan device
+memory available without switching your graphics card to one that really has
+smaller VRAM, you can use a feature of this library intended for this purpose.
+To do it, fill optional member VmaAllocatorCreateInfo::pHeapSizeLimit.
+
+
+
+\page vk_khr_dedicated_allocation VK_KHR_dedicated_allocation
+
+VK_KHR_dedicated_allocation is a Vulkan extension which can be used to improve
+performance on some GPUs. It augments Vulkan API with possibility to query
+driver whether it prefers particular buffer or image to have its own, dedicated
+allocation (separate `VkDeviceMemory` block) for better efficiency - to be able
+to do some internal optimizations.
+
+The extension is supported by this library. It will be used automatically when
+enabled. To enable it:
+
+1 . When creating Vulkan device, check if following 2 device extensions are
+supported (call `vkEnumerateDeviceExtensionProperties()`).
+If yes, enable them (fill `VkDeviceCreateInfo::ppEnabledExtensionNames`).
+
+- VK_KHR_get_memory_requirements2
+- VK_KHR_dedicated_allocation
+
+If you enabled these extensions:
+
+2 . Use #VMA_ALLOCATOR_CREATE_KHR_DEDICATED_ALLOCATION_BIT flag when creating
+your #VmaAllocator`to inform the library that you enabled required extensions
+and you want the library to use them.
+
+\code
+allocatorInfo.flags |= VMA_ALLOCATOR_CREATE_KHR_DEDICATED_ALLOCATION_BIT;
+
+vmaCreateAllocator(&allocatorInfo, &allocator);
+\endcode
+
+That's all. The extension will be automatically used whenever you create a
+buffer using vmaCreateBuffer() or image using vmaCreateImage().
+
+When using the extension together with Vulkan Validation Layer, you will receive
+warnings like this:
+
+    vkBindBufferMemory(): Binding memory to buffer 0x33 but vkGetBufferMemoryRequirements() has not been called on that buffer.
+
+It is OK, you should just ignore it. It happens because you use function
+`vkGetBufferMemoryRequirements2KHR()` instead of standard
+`vkGetBufferMemoryRequirements()`, while the validation layer seems to be
+unaware of it.
+
+To learn more about this extension, see:
+
+- [VK_KHR_dedicated_allocation in Vulkan specification](https://www.khronos.org/registry/vulkan/specs/1.0-extensions/html/vkspec.html#VK_KHR_dedicated_allocation)

+
+
+
+\page general_considerations General considerations
+
+\section general_considerations_thread_safety Thread safety
+
+- The library has no global state, so separate #VmaAllocator objects can be used
+  independently.
+  There should be no need to create multiple such objects though - one per `VkDevice` is enough.
+- By default, all calls to functions that take #VmaAllocator as first parameter
+  are safe to call from multiple threads simultaneously because they are
+  synchronized internally when needed.
+- When the allocator is created with #VMA_ALLOCATOR_CREATE_EXTERNALLY_SYNCHRONIZED_BIT
+  flag, calls to functions that take such #VmaAllocator object must be
+  synchronized externally.
+- Access to a #VmaAllocation object must be externally synchronized. For example,
+  you must not call vmaGetAllocationInfo() and vmaMapMemory() from different
+  threads at the same time if you pass the same #VmaAllocation object to these
+  functions.
+
+\section general_considerations_validation_layer_warnings Validation layer warnings
+
+When using this library, you can meet following types of warnings issued by
+Vulkan validation layer. They don't necessarily indicate a bug, so you may need
+to just ignore them.
+
+- *vkBindBufferMemory(): Binding memory to buffer 0xeb8e4 but vkGetBufferMemoryRequirements() has not been called on that buffer.*
+  - It happens when VK_KHR_dedicated_allocation extension is enabled.
+    `vkGetBufferMemoryRequirements2KHR` function is used instead, while validation layer seems to be unaware of it.
+- *Mapping an image with layout VK_IMAGE_LAYOUT_DEPTH_STENCIL_ATTACHMENT_OPTIMAL can result in undefined behavior if this memory is used by the device. Only GENERAL or PREINITIALIZED should be used.*
+  - It happens when you map a buffer or image, because the library maps entire
+    `VkDeviceMemory` block, where different types of images and buffers may end
+    up together, especially on GPUs with unified memory like Intel.
+- *Non-linear image 0xebc91 is aliased with linear buffer 0xeb8e4 which may indicate a bug.*
+  - It happens when you use lost allocations, and a new image or buffer is
+    created in place of an existing object that bacame lost.
+  - It may happen also when you use [defragmentation](@ref defragmentation).
+
+\section general_considerations_allocation_algorithm Allocation algorithm
+
+The library uses following algorithm for allocation, in order:
+
+-# Try to find free range of memory in existing blocks.
+-# If failed, try to create a new block of `VkDeviceMemory`, with preferred block size.
+-# If failed, try to create such block with size/2, size/4, size/8.
+-# If failed and #VMA_ALLOCATION_CREATE_CAN_MAKE_OTHER_LOST_BIT flag was
+   specified, try to find space in existing blocks, possilby making some other
+   allocations lost.
+-# If failed, try to allocate separate `VkDeviceMemory` for this allocation,
+   just like when you use #VMA_ALLOCATION_CREATE_DEDICATED_MEMORY_BIT.
+-# If failed, choose other memory type that meets the requirements specified in
+   VmaAllocationCreateInfo and go to point 1.
+-# If failed, return `VK_ERROR_OUT_OF_DEVICE_MEMORY`.
+
+\section general_considerations_features_not_supported Features not supported
+
+Features deliberately excluded from the scope of this library:
+
+- Data transfer. Uploading (straming) and downloading data of buffers and images
+  between CPU and GPU memory and related synchronization is responsibility of the user.
+  Defining some "texture" object that would automatically stream its data from a
+  staging copy in CPU memory to GPU memory would rather be a feature of another,
+  higher-level library implemented on top of VMA.
+- Allocations for imported/exported external memory. They tend to require
+  explicit memory type index and dedicated allocation anyway, so they don't
+  interact with main features of this library. Such special purpose allocations
+  should be made manually, using `vkCreateBuffer()` and `vkAllocateMemory()`.
+- Recreation of buffers and images. Although the library has functions for
+  buffer and image creation (vmaCreateBuffer(), vmaCreateImage()), you need to
+  recreate these objects yourself after defragmentation. That's because the big
+  structures `VkBufferCreateInfo`, `VkImageCreateInfo` are not stored in
+  #VmaAllocation object.
+- Handling CPU memory allocation failures. When dynamically creating small C++
+  objects in CPU memory (not Vulkan memory), allocation failures are not checked
+  and handled gracefully, because that would complicate code significantly and
+  is usually not needed in desktop PC applications anyway.
+- Code free of any compiler warnings. Maintaining the library to compile and
+  work correctly on so many different platforms is hard enough. Being free of
+  any warnings, on any version of any compiler, is simply not feasible.
+- This is a C++ library with C interface.
+  Bindings or ports to any other programming languages are welcomed as external projects and
+  are not going to be included into this repository.

+
+This function works by moving allocations to different places (different
+`VkDeviceMemory` objects and/or different offsets) in order to optimize memory
+usage. Only allocations that are in `pAllocations` array can be moved. All other
+allocations are considered nonmovable in this call. Basic rules:
+
+- Only allocations made in memory types that have
+  `VK_MEMORY_PROPERTY_HOST_VISIBLE_BIT` and `VK_MEMORY_PROPERTY_HOST_COHERENT_BIT`
+  flags can be compacted. You may pass other allocations but it makes no sense -
+  these will never be moved.
+- Custom pools created with #VMA_POOL_CREATE_LINEAR_ALGORITHM_BIT or
+  #VMA_POOL_CREATE_BUDDY_ALGORITHM_BIT flag are not defragmented. Allocations
+  passed to this function that come from such pools are ignored.
+- Allocations created with #VMA_ALLOCATION_CREATE_DEDICATED_MEMORY_BIT or
+  created as dedicated allocations for any other reason are also ignored.
+- Both allocations made with or without #VMA_ALLOCATION_CREATE_MAPPED_BIT
+  flag can be compacted. If not persistently mapped, memory will be mapped
+  temporarily inside this function if needed.
+- You must not pass same #VmaAllocation object multiple times in `pAllocations` array.
+
+The function also frees empty `VkDeviceMemory` blocks.
+
+Warning: This function may be time-consuming, so you shouldn't call it too often
+(like after every resource creation/destruction).
+You can call it on special occasions (like when reloading a game level or
+when you just destroyed a lot of objects). Calling it every frame may be OK, but
+you should measure that on your platform.

+For more information, see [Defragmentation](@ref defragmentation) chapter.

+// The SPIR-V spec requires code blocks to appear in an order satisfying the
+// dominator-tree direction (ie, dominator before the dominated).  This is,
+// actually, easy to achieve: any pre-order CFG traversal algorithm will do it.
+// Because such algorithms visit a block only after traversing some path to it
+// from the root, they necessarily visit the block's idom first.
+//
+// But not every graph-traversal algorithm outputs blocks in an order that
+// appears logical to human readers.  The problem is that unrelated branches may
+// be interspersed with each other, and merge blocks may come before some of the
+// branches being merged.
+//
+// A good, human-readable order of blocks may be achieved by performing
+// depth-first search but delaying merge nodes until after all their branches
+// have been visited.  This is implemented below by the inReadableOrder()
+// function.

+// Enumeration tokens for SPIR-V, in various styles:
+//   C, C++, C++11, JSON, Lua, Python, C#, D
+// 
+// - C will have tokens with a "Spv" prefix, e.g.: SpvSourceLanguageGLSL
+// - C++ will have tokens in the "spv" name space, e.g.: spv::SourceLanguageGLSL
+// - C++11 will use enum classes in the spv namespace, e.g.: spv::SourceLanguage::GLSL
+// - Lua will use tables, e.g.: spv.SourceLanguage.GLSL
+// - Python will use dictionaries, e.g.: spv['SourceLanguage']['GLSL']
+// - C# will use enum classes in the Specification class located in the "Spv" namespace,
+//     e.g.: Spv.Specification.SourceLanguage.GLSL
+// - D will have tokens under the "spv" module, e.g: spv.SourceLanguage.GLSL
+// 
+// Some tokens act like mask values, which can be OR'd together,
+// while others are mutually exclusive.  The mask-like ones have
+// "Mask" in their name, and a parallel enum that has the shift
+// amount (1 << x) for each corresponding enumerant.

+
+//
+// Symbol table for parsing.  Has these design characteristics:
+//
+// * Same symbol table can be used to compile many shaders, to preserve
+//   effort of creating and loading with the large numbers of built-in
+//   symbols.
+//
+// -->  This requires a copy mechanism, so initial pools used to create
+//   the shared information can be popped.  Done through "clone"
+//   methods.
+//
+// * Name mangling will be used to give each function a unique name
+//   so that symbol table lookups are never ambiguous.  This allows
+//   a simpler symbol table structure.
+//
+// * Pushing and popping of scope, so symbol table will really be a stack
+//   of symbol tables.  Searched from the top, with new inserts going into
+//   the top.
+//
+// * Constants:  Compile time constant symbols will keep their values
+//   in the symbol table.  The parser can substitute constants at parse
+//   time, including doing constant folding and constant propagation.
+//
+// * No temporaries:  Temporaries made from operations (+, --, .xy, etc.)
+//   are tracked in the intermediate representation, not the symbol table.

+// Help manage multiple profiles, versions, extensions etc.
+//
+// These don't return error codes, as the presumption is parsing will
+// always continue as if the tested feature were enabled, and thus there
+// is no error recovery needed.
+//
+
+//
+// HOW TO add a feature enabled by an extension.
+//
+// To add a new hypothetical "Feature F" to the front end, where an extension
+// "XXX_extension_X" can be used to enable the feature, do the following.
+//
+// OVERVIEW: Specific features are what are error-checked for, not
+//    extensions:  A specific Feature F might be enabled by an extension, or a
+//    particular version in a particular profile, or a stage, or combinations, etc.
+//
+//    The basic mechanism is to use the following to "declare" all the things that
+//    enable/disable Feature F, in a code path that implements Feature F:
+//
+//        requireProfile()
+//        profileRequires()
+//        requireStage()
+//        checkDeprecated()
+//        requireNotRemoved()
+//        requireExtensions()
+//
+//    Typically, only the first two calls are needed.  They go into a code path that
+//    implements Feature F, and will log the proper error/warning messages.  Parsing
+//    will then always continue as if the tested feature was enabled.
+//
+//    There is typically no if-testing or conditional parsing, just insertion of the calls above.
+//    However, if symbols specific to the extension are added (step 5), they will
+//    only be added under tests that the minimum version and profile are present.
+//
+// 1) Add a symbol name for the extension string at the bottom of Versions.h:
+//
+//     const char* const XXX_extension_X = "XXX_extension_X";
+//
+// 2) Add extension initialization to TParseVersions::initializeExtensionBehavior(),
+//    the first function below:
+//
+//     extensionBehavior[XXX_extension_X] = EBhDisable;
+//
+// 3) Add any preprocessor directives etc. in the next function, TParseVersions::getPreamble():
+//
+//           "#define XXX_extension_X 1\n"
+//
+//    The new-line is important, as that ends preprocess tokens.
+//
+// 4) Insert a profile check in the feature's path (unless all profiles support the feature,
+//    for some version level).  That is, call requireProfile() to constrain the profiles, e.g.:
+//
+//         // ... in a path specific to Feature F...
+//         requireProfile(loc,
+//                        ECoreProfile | ECompatibilityProfile,
+//                        "Feature F");
+//
+// 5) For each profile that supports the feature, insert version/extension checks:
+//
+//    The mostly likely scenario is that Feature F can only be used with a
+//    particular profile if XXX_extension_X is present or the version is
+//    high enough that the core specification already incorporated it.
+//
+//        // following the requireProfile() call...
+//        profileRequires(loc,
+//                        ECoreProfile | ECompatibilityProfile,
+//                        420,             // 0 if no version incorporated the feature into the core spec.
+//                        XXX_extension_X, // can be a list of extensions that all add the feature
+//                        "Feature F Description");
+//
+//    This allows the feature if either A) one of the extensions is enabled or
+//    B) the version is high enough.  If no version yet incorporates the feature
+//    into core, pass in 0.
+//
+//    This can be called multiple times, if different profiles support the
+//    feature starting at different version numbers or with different
+//    extensions.
+//
+//    This must be called for each profile allowed by the initial call to requireProfile().
+//
+//    Profiles are all masks, which can be "or"-ed together.
+//
+//        ENoProfile
+//        ECoreProfile
+//        ECompatibilityProfile
+//        EEsProfile
+//
+//    The ENoProfile profile is only for desktop, before profiles showed up in version 150;
+//    All other #version with no profile default to either es or core, and so have profiles.
+//
+//    You can select all but a particular profile using ~.  The following basically means "desktop":
+//
+//        ~EEsProfile
+//
+// 6) If built-in symbols are added by the extension, add them in Initialize.cpp:  Their use
+//    will be automatically error checked against the extensions enabled at that moment.
+//    see the comment at the top of Initialize.cpp for where to put them.  Establish them at
+//    the earliest release that supports the extension.  Then, tag them with the
+//    set of extensions that both enable them and are necessary, given the version of the symbol
+//    table. (There is a different symbol table for each version.)

+/* Based on:
+ANSI C Yacc grammar
+
+In 1985, Jeff Lee published his Yacc grammar (which is accompanied by a
+matching Lex specification) for the April 30, 1985 draft version of the
+ANSI C standard.  Tom Stockfisch reposted it to net.sources in 1987; that
+original, as mentioned in the answer to question 17.25 of the comp.lang.c
+FAQ, can be ftp'ed from ftp.uu.net, file usenet/net.sources/ansi.c.grammar.Z.
+
+I intend to keep this version as close to the current C Standard grammar as
+possible; please let me know if you discover discrepancies.

+       action, or user semantic action that manipulated yychar.

+    // the base offset up to a multiple of the base alignment. The base offset of the first
+    // member of a structure is taken from the aligned offset of the structure itself. The
+    // base offset of all other structure members is derived by taking the offset of the
+    // last basic machine unit consumed by the previous member and adding one. Each
+    // structure member is stored in memory at its aligned offset. The members of a top-
+    // level uniform block are laid out in buffer storage by treating the uniform block as
+    // a structure with a base offset of zero.
+    //
+    //   1. If the member is a scalar consuming N basic machine units, the base alignment is N.
+    //
+    //   2. If the member is a two- or four-component vector with components consuming N basic
+    //      machine units, the base alignment is 2N or 4N, respectively.
+    //
+    //   3. If the member is a three-component vector with components consuming N
+    //      basic machine units, the base alignment is 4N.
+    //
+    //   4. If the member is an array of scalars or vectors, the base alignment and array
+    //      stride are set to match the base alignment of a single array element, according
+    //      to rules (1), (2), and (3), and rounded up to the base alignment of a vec4. The
+    //      array may have padding at the end; the base offset of the member following
+    //      the array is rounded up to the next multiple of the base alignment.
+    //
+    //   5. If the member is a column-major matrix with C columns and R rows, the
+    //      matrix is stored identically to an array of C column vectors with R
+    //      components each, according to rule (4).
+    //
+    //   6. If the member is an array of S column-major matrices with C columns and
+    //      R rows, the matrix is stored identically to a row of S X C column vectors
+    //      with R components each, according to rule (4).
+    //
+    //   7. If the member is a row-major matrix with C columns and R rows, the matrix
+    //      is stored identically to an array of R row vectors with C components each,
+    //      according to rule (4).
+    //
+    //   8. If the member is an array of S row-major matrices with C columns and R
+    //      rows, the matrix is stored identically to a row of S X R row vectors with C
+    //      components each, according to rule (4).
+    //
+    //   9. If the member is a structure, the base alignment of the structure is N , where
+    //      N is the largest base alignment value of any    of its members, and rounded
+    //      up to the base alignment of a vec4. The individual members of this substructure
+    //      are then assigned offsets by applying this set of rules recursively,
+    //      where the base offset of the first member of the sub-structure is equal to the
+    //      aligned offset of the structure. The structure may have padding at the end;
+    //      the base offset of the member following the sub-structure is rounded up to
+    //      the next multiple of the base alignment of the structure.
