Various fixes to UV2 unwrapping and the GPU lightmapper. Listed here for
context in case of git blame/bisect:
* Fix UV2 unwrapping on import, also cleaned up the unwrap cache code.
* Fix saving of RGBA images in EXR format.
* Fixes to the GPU lightmapper:
- Added padding between atlas elements, avoids bleeding.
- Remove old SDF generation code.
- Fix baked attenuation for Omni/Spot lights.
- Fix baking of material properties onto UV2 (wireframe was
wrongly used before).
- Disable statically baked lights for objects that have a
lightmap texture to avoid applying the same light twice.
- Fix lightmap pairing in RendererSceneCull.
- Fix UV2 array generated from `RenderingServer::mesh_surface_get_arrays()`.
- Port autoexposure fix for OIDN from 3.x.
- Save debug textures as EXR when using floating point format.

Core: Drop custom `copymem`/`zeromem` defines
|
|
|
|
We've been using standard C library functions `memcpy`/`memset` for these since
2016 with 67f65f66391327b2967a20a89c3627e1dd6e84eb.
There was still the possibility for third-party platform ports to override the
definitions with a custom header, but this doesn't seem useful anymore.

A few single line comments were duplicated, probably due to bad merges.
This commit removes the obviously duplicate ones.

update meshoptimizer to version 0.16
|
|
|
|
Avoid unnecessary allocation of temporary buffers for each mip, and creates
only one Image with the compressed data.
Also renames variable and reorders code for clarity.
Clarify that squish is now only used for decompression.
Documented which formats can be decompressed in Image.
|
|
We do our own image loading, threading, and memory management in Godot already,
so the only components we need from etcpak (at least as of now) are the
`Compress*` methods defined in `ProcessDxtc.cpp` and `ProcessRGB.cpp`.
So we don't need to compile or vendor the rest.

For MinGW this is tricky to do as a two-step process like it was implemented,
as `std::thread::native_handle()` is implementation-defined and depending on
the MinGW distribution, it may or may not be a pthread handle.
With mingw-gcc as packaged in Linux distros with pthread support it worked
fine, but with llvm-mingw it was problematic.
Setting the name in the thread directly as done for Apple platforms is simpler
and works fine.

- `etc` module was renamed to `etcpak` and modified to use the new library.
- PKM importer is removed in the process, it's obsolete.
- Old library `etc2comp` is removed.
- S3TC compression no longer done via `squish` (but decompression still is).
- Slight modifications to etcpak sources for MinGW compatibility,
to fix LLVM `-Wc++11-narrowing` errors, and to allow using vendored or
system libpng.

The patch has already been upstreamed, and custom patching won't be
needed during next version update.

This is a tricky one, it used to work, but it was wrong, because in such
a scenario instead of passing NULL as required by the API, it would pass
a buffer containing the `\0` terminator.
This stopped working on a specific miniupnpc version, when they fixed
some network endianess issue on Windows, to which we made a workaround,
which in turn would probably result in failures when the interface is
specified.
This commit address the issue properly, by checking the specified
interface string size, and correctly passing NULL instead of the empty
string when necessary.
Also reverts the commit that introduced the bogus workaround:

One of those PR when the explaination is much longer then code changes
:).

enet: Sync with upstream 1.3.17
|
|
Also include public domain assets in `COPYRIGHT.txt` with Unlicence text or
dual-licensing scheme.
And document commit hashes for most thirdparty code in `thirdparty/README.md`
for clarity, and in case there's no tag matching the included version numbers.

zstd: Update to upstream version 1.4.8

Make ClassDB test macros enforce their msg to be constructed as String,
since doctest 2.4.2 changes the message passing to vararg.

Happy new year to the wonderful Godot community!
2020 has been a tough year for most of us personally, but a good year for
Godot development nonetheless with a huge amount of work done towards Godot
4.0 and great improvements backported to the long-lived 3.2 branch.
We've had close to 400 contributors to engine code this year, authoring near
7,000 commit! (And that's only for the `master` branch and for the engine code,
there's a lot more when counting docs, demos and other first-party repos.)
Here's to a great year 2021 for all Godot users 🎆

Vulkan: loader, headers, and glslang updated to sdk-1.2.162.0
|
|
|
|
Updated glslang and Vulkan headers/loader following the instructions found in thirdparty/README.
glslang was updated to the 'known good' matching Vulkan SDK version 1.2.162.0. Vulkan headers and loader were updated to the commit tagged with sdk-1.2.162.0.
'vk_mem_alloc.h' and 'vk_mem_alloc.c' are unchanged since there hasn't been a new tagged release since 2.3.0.
Here's the Vulkan release notes for this update:
https://vulkan.lunarg.com/doc/sdk/1.2.162.0/windows/release_notes.html
Reverted and removed the unnecessary fix-mingw-snprintf patch for glslang as well as the mention of it in thirdparty/README.md.
