Why Vulkan Header Files Here?

The vulkan_core.h included here is custom generated from the Vulkan Registry's vk.xml in order to include the format enumerators for the ASTC 3d formats. We need to support these formats because there are OpenGL implementations even though, as yet, there are no Vulkan implementations.

See ./build_custom_vulkan_core for instructions on generating the file.

vulkan_core.h is used to generate the switch bodies dfd2vk.inl and vk2dfd.inl.

To Do

Generate the switch bodies from vk.xml instead.
