Description
VK_KHR_maintenance8 adds a collection of minor features, none of which would warrant an entire extension of their own.
The new features are as follows:
- 
Allow copies between depth/stencil and “matching” color attachments 
- 
Allow dstCacheinvkMergePipelineCachesto be implicitly synchronized.
- 
Require src/dst sync scopes to work when doing queue family ownership transfers 
- 
Support Offset(as an alternative toConstOffset) image operand in texture sampling and fetch operations
- 
Use the SPIR-V definition of OpSRemandOpSMod, making these operations produce well-defined results for negative operands
- 
Loosen layer restrictions when blitting from 3D images to other image types 
- 
Add space for an additional 64 access flags for use with VkMemoryBarrier2, VkBufferMemoryBarrier2, and VkImageMemoryBarrier2
