  Message : Vulkan: Simplify format table generation Remove the "override" table. That gets in the way of some solutions. If a format cannot be supported by a native Vulkan format as indicated in the "map" table, then check fallbacks. Also add support for native RGBA4 and R5G5B5A1 support. Previously those formats would be emulated with RGBA8 due to the override, but now code will check if the native format is available and use it.
