 	<description>
+		For complex arrangements of shapes it is sometimes needed to add structure to your CSG nodes. The CSGCombiner node allows you to create this structure. The node encapsulates the result of the CSG operations of its children. In this way it is possible to do operations on one set of shapes that are children of one CSGCombiner node, and a set of separate operations on a second set of shapes that are children of a second CSGCombiner node, and then do an operation that takes the two end results as their input to create the final shape.

+ *             the same nonce and key.
+ *
+ *             There are two common strategies for managing nonces with CTR:
+ *
+ *             1. You can handle everything as a single message processed over
+ *             successive calls to this function. In that case, you want to
+ *             set \p nonce_counter and \p nc_off to 0 for the first call, and
+ *             then preserve the values of \p nonce_counter, \p nc_off and \p
+ *             stream_block across calls to this function as they will be
+ *             updated by this function.
+ *
+ *             With this strategy, you must not encrypt more than 2**128
+ *             blocks of data with the same key.
+ *
+ *             2. You can encrypt separate messages by dividing the \p
+ *             nonce_counter buffer in two areas: the first one used for a
+ *             per-message nonce, handled by yourself, and the second one
+ *             updated by this function internally.
+ *
+ *             For example, you might reserve the first 12 bytes for the
+ *             per-message nonce, and the last 4 bytes for internal use. In that
+ *             case, before calling this function on a new message you need to
+ *             set the first 12 bytes of \p nonce_counter to your chosen nonce
+ *             value, the last 4 to 0, and \p nc_off to 0 (which will cause \p
+ *             stream_block to be ignored). That way, you can encrypt at most
+ *             2**96 messages of up to 2**32 blocks each with the same key.
+ *
+ *             The per-message nonce (or information sufficient to reconstruct
+ *             it) needs to be communicated with the ciphertext and must be unique.
+ *             The recommended way to ensure uniqueness is to use a message
+ *             counter. An alternative is to generate random nonces, but this
+ *             limits the number of messages that can be securely encrypted:
+ *             for example, with 96-bit random nonces, you should not encrypt
+ *             more than 2**32 messages with the same key.
+ *
+ *             Note that for both stategies, sizes are measured in blocks and
+ *             that an AES block is 16 bytes.
+ *
+ * \warning    Upon return, \p stream_block contains sensitive data. Its
+ *             content must not be written to insecure storage and should be
+ *             securely discarded as soon as it's no longer needed.

+ *             would void the encryption for the two messages encrypted with
+ *             the same nonce and key.
+ *
+ *             There are two common strategies for managing nonces with CTR:
+ *
+ *             1. You can handle everything as a single message processed over
+ *             successive calls to this function. In that case, you want to
+ *             set \p nonce_counter and \p nc_off to 0 for the first call, and
+ *             then preserve the values of \p nonce_counter, \p nc_off and \p
+ *             stream_block across calls to this function as they will be
+ *             updated by this function.
+ *
+ *             With this strategy, you must not encrypt more than 2**128
+ *             blocks of data with the same key.
+ *
+ *             2. You can encrypt separate messages by dividing the \p
+ *             nonce_counter buffer in two areas: the first one used for a
+ *             per-message nonce, handled by yourself, and the second one
+ *             updated by this function internally.
+ *
+ *             For example, you might reserve the first 12 bytes for the
+ *             per-message nonce, and the last 4 bytes for internal use. In that
+ *             case, before calling this function on a new message you need to
+ *             set the first 12 bytes of \p nonce_counter to your chosen nonce
+ *             value, the last 4 to 0, and \p nc_off to 0 (which will cause \p
+ *             stream_block to be ignored). That way, you can encrypt at most
+ *             2**96 messages of up to 2**32 blocks each with the same key.
+ *
+ *             The per-message nonce (or information sufficient to reconstruct
+ *             it) needs to be communicated with the ciphertext and must be unique.
+ *             The recommended way to ensure uniqueness is to use a message
+ *             counter. An alternative is to generate random nonces, but this
+ *             limits the number of messages that can be securely encrypted:
+ *             for example, with 96-bit random nonces, you should not encrypt
+ *             more than 2**32 messages with the same key.
+ *
+ *             Note that for both stategies, sizes are measured in blocks and
+ *             that an ARIA block is 16 bytes.
+ *
+ * \warning    Upon return, \p stream_block contains sensitive data. Its
+ *             content must not be written to insecure storage and should be
+ *             securely discarded as soon as it's no longer needed.
+ *
+ * \param ctx              The ARIA context to use for encryption or decryption.
+ * \param length           The length of the input data.
+ * \param nc_off           The offset in the current \p stream_block, for
+ *                         resuming within the current cipher stream. The
+ *                         offset pointer should be 0 at the start of a stream.

+ * \param stream_block     The saved stream block for resuming. This is
+ *                         overwritten by the function.

+ *                   initially available on the underlying transport, as this data may have
+ *                   been only e.g. duplicated messages or a renegotiation request.

+ *                   when reacting to an incoming-data event from the underlying transport.
+ *                 - On success, the datagram of the underlying transport that is currently

+ * This implementation should never be optimized out by the compiler

+ * Percival's blog article at:
+ *
+ * http://www.daemonology.net/blog/2014-09-04-how-to-zero-a-buffer.html
+ *
+ * It uses a volatile function pointer to the standard memset(). Because the
+ * pointer is volatile the compiler expects it to change at
+ * any time and will not optimize out the call that could potentially perform
+ * other operations on the input buffer instead of just setting it to 0.
+ * Nevertheless, as pointed out by davidtgoldblatt on Hacker News
+ * (refer to http://www.daemonology.net/blog/2014-09-05-erratum.html for
+ * details), optimizations of the following form are still possible:
+ *
+ * if( memset_func != memset )
+ *     memset_func( buf, 0, len );
+ *
+ * Note that it is extremely difficult to guarantee that
+ * mbedtls_platform_zeroize() will not be optimized out by aggressive compilers
+ * in a portable way. For this reason, Mbed TLS also provides the configuration
+ * option MBEDTLS_PLATFORM_ZEROIZE_ALT, which allows users to configure
+ * mbedtls_platform_zeroize() to use a suitable implementation for their
+ * platform and needs.

+ * The rationale for this rule is that someone could have a list of trusted
+ * roots with two versions on the same root with different validity periods.
+ * (At least one user reported having such a list and wanted it to just work.)
+ * The reason we don't just require time-validity is that generally there is
+ * only one version, and if it's expired we want the flags to state that
+ * rather than NOT_TRUSTED, as would be the case if we required it here.
+ *
+ * The rationale for rule 3 (signature for trusted roots) is that users might
+ * have two versions of the same CA with different keys in their list, and the
+ * way we select the correct one is by checking the signature (as we don't
+ * rely on key identifier extensions). (This is one way users might choose to
+ * handle key rollover, another relies on self-issued certs, see [SIRO].)
+ *
+ * Arguments:
+ *  - [in] child: certificate for which we're looking for a parent
+ *  - [in] candidates: chained list of potential parents
+ *  - [in] top: 1 if candidates consists of trusted roots, ie we're at the top
+ *         of the chain, 0 otherwise
+ *  - [in] path_cnt: number of intermediates seen so far
+ *  - [in] self_cnt: number of self-signed intermediates seen so far
+ *         (will never be greater than path_cnt)
+ *
+ * Return value:
+ *  - the first suitable parent found (see above regarding time-validity)
+ *  - NULL if no suitable parent was found

-****************************************************************************
-                   RECURSION IN THE match() FUNCTION
-
-The match() function is highly recursive, though not every recursive call
-increases the recursion depth. Nevertheless, some regular expressions can cause
-it to recurse to a great depth. I was writing for Unix, so I just let it call
-itself recursively. This uses the stack for saving everything that has to be
-saved for a recursive call. On Unix, the stack can be large, and this works
-fine.
-
-It turns out that on some non-Unix-like systems there are problems with
-programs that use a lot of stack. (This despite the fact that every last chip
-has oodles of memory these days, and techniques for extending the stack have
-been known for decades.) So....
-
-There is a fudge, triggered by defining HEAP_MATCH_RECURSE, which avoids
-recursive calls by keeping local variables that need to be preserved in blocks
-of memory on the heap instead instead of on the stack. Macros are used to
-achieve this so that the actual code doesn't look very different to what it
-always used to.
-
-The original heap-recursive code used longjmp(). However, it seems that this
-can be very slow on some operating systems. Following a suggestion from Stan
-Switzer, the use of longjmp() has been abolished, at the cost of having to
-provide a unique number for each call to RMATCH. There is no way of generating
-a sequence of numbers at compile time in C. I have given them names, to make
-them stand out more clearly.
-
-Crude tests on x86 Linux show a small speedup of around 5-8%. However, on
-FreeBSD, avoiding longjmp() more than halves the time taken to run the standard
-tests. Furthermore, not using longjmp() means that local dynamic variables
-don't have indeterminate values; this has meant that the frame size can be
-reduced because the result can be "passed back" by straight setting of the
-variable instead of being passed in the frame.

-  The purpose of this definition is convenience. Although a register
-  is either scratch register or saved register, SLJIT allows accessing
-  them from the other set. For example, four registers can be used as
-  scratch registers and the fifth one as saved register on the architecture
-  above. Of course the last two scratch registers (R2 and R3) from this
-  four will be saved on the stack, because they are defined as saved
-  registers in the application binary interface. Still R2 and R3 can be
-  used for referencing to these registers instead of S2 and S1, which
-  makes easier to write platform independent code. Scratch registers
-  can be saved registers in a similar way, but these extra saved
-  registers will not be preserved across function calls! Hence the
-  application must save them on those platforms, where the number of
-  saved registers is too low. This can be done by copy them onto
-  the stack and restore them after a function call.
+  The purpose of this definition is convenience: saved registers can
+  be used as extra scratch registers. For example four registers can
+  be specified as scratch registers and the fifth one as saved register
+  on the CPU above and any user code which requires four scratch
+  registers can run unmodified. The SLJIT compiler automatically saves
+  the content of the two extra scrath register on the stack. Scratch
+  registers can also be preserved by saving their value on the stack
+  but this needs to be done manually.
 
   Note: To emphasize that registers assigned to R2-R4 are saved

   Note: sljit_emit_enter and sljit_set_context defines whether a register

+       Sets the zero flag if the result is zero, clears it otherwise.
+       Sets the variable flag if unsigned overflow (carry) occurs,
+       clears it otherwise.
+
+   If an instruction (e.g. SLJIT_MOV) does not modify flags the flags are
+   unchanged.
+
+   Using these flags can reduce the number of emitted instructions. E.g. a
+   fast loop can be implemented by decreasing a counter register and set the
+   zero flag to jump back if the counter register is not reached zero.
+
+   Motivation: although CPUs can set a large number of flags, usually their
+   values are ignored or only one of them is used. Emulating a large number
+   of flags on systems without flag register is complicated so SLJIT
+   instructions must specify the flag they want to use and only that flag
+   will be emulated. The last arithmetic instruction can be repeated if
+   multiple flags needs to be checked.

+   This file contains a simple executable memory allocator
+
+   It is assumed, that executable code blocks are usually medium (or sometimes
+   large) memory blocks, and the allocator is not too frequently called (less
+   optimized than other allocators). Thus, using it as a generic allocator is
+   not suggested.
+
+   How does it work:
+     Memory is allocated in continuous memory areas called chunks by alloc_chunk()
+     Chunk format:
+     [ block ][ block ] ... [ block ][ block terminator ]
+
+   All blocks and the block terminator is started with block_header. The block
+   header contains the size of the previous and the next block. These sizes
+   can also contain special values.
+     Block size:
+       0 - The block is a free_block, with a different size member.
+       1 - The block is a block terminator.
+       n - The block is used at the moment, and the value contains its size.
+     Previous block size:
+       0 - This is the first block of the memory chunk.
+       n - The size of the previous block.
+
+   Using these size values we can go forward or backward on the block chain.
+   The unused blocks are stored in a chain list pointed by free_blocks. This
+   list is useful if we need to find a suitable memory area when the allocator
+   is called.
+
+   When a block is freed, the new free block is connected to its adjacent free
+   blocks if possible.
+
+     [ free block ][ used block ][ free block ]
+   and "used block" is freed, the three blocks are connected together:
+     [           one big free block           ]
