-* meshletdec.slang - an example GPU decoder for meshlet data encoded using meshopt_encodeMeshlet
-* This is intended to be used as a starting point for applications that want to decode meshlet data on the GPU.
-*
-* The shader exposes an entrypoint, decodeMeshlets, that decodes a set of meshlets; each meshlet is decoded independently,
-* and the output vertex/triangle data is written as uint32 per element (triangle data is written as 0xabc).
-* This matches the output format for meshopt_decodeMeshlet with vertex_size=4 triangle_size=4. If alternative formats are
-* needed, the code should be changed to output them; note that for triangle data, it may make sense to output data to shared
-* memory to be able to use larger aligned 32-bit writes to global memory after that.
