VK_EXT_memory_decompression

This extension adds support for performing memory to memory decompression.

1) How does an app know the minimum size that decompressedSize should be set to?

RESOLVED: When decompressing, data is typically processed in chunks. For example, with GDeflate 1.0, data is streamed in 64 KB blocks, but the final block may be smaller. The exact size of this last block depends on the compression method and original data size and so it must be stored in the compressed bitstream so that the decompressor can set decompressedSize correctly. It is still ok for the last block to take up all 64 KB, but setting it too low will cause issues and is undefined behavior. It is a known limitation that the validation layers will not be able to detect the minimum size of decompressedSize unless it decides to implement each decompression method specification.
