Vulkan 1.1.122 Brings Extension Documenting Proprietary Imagination Tech Bits

Linux/open-source fans don't at least have to hear "Imagination Technologies" or PowerVR as often as in the past, but today's Vulkan 1.1.122 specification update does publicly document Imagination's VK_IMG_format_pvrtc extension that remains "Imagination Technologies Proprietary" licensed.

The VK_IMG_format_pvrtc Vulkan extension has been around but not publicly document. This extension exposes additional texture compression features specific to Imagination PowerVR texture compression formats (PVRTC). There had been this two year old issue report over the VK_IMG_format_pvrtc extension not being public and they had been unable to provide the documentation over legal grounds. Earlier this year Imagination did provide a PVRTC texture compression user guide and now with Vulkan 1.1.122 they have finally documented this extension. The extension documentation is basically pointing out a number of different enums.

That is the only "new" extension with Vulkan 1.1.122 while the other work is various document clarifications, deprecating the VK_EXT_validation_flags extension, the documentation scripts are closer to being in sync with the OpenXR generators, and various other specification corrections.
