The subset of Vulkan's VkFormat this loader maps to a TextureFormat.
Not one to one: an _SRGB value and its _UNORM twin carry the same bits
and map to the same engine format, because this engine's shaders decode
sRGB themselves and a sampler that also decoded would decode twice. See
_engineFormat in ktx2_loader.dart, which says why at length.
Numbers are Khronos's, not this repository's: taken from
github.com/KhronosGroup/KTX-Software/lib/src/vkformat_enum.h, the
project that defines what a KTX2 file's vkFormat field means. Copied
rather than derived, for the reason formats.dart states about the
flutter_gpu mirror — a wrong number here compiles, runs, and renders wrong
only for the value a scene happens to use.
