Like the Vulkan backend, with "Auto Max Quality" texture filtering give
textures up to 256x256 a full mip chain, generating the levels the game
didn't supply with a blit. Mipmapping is now controlled by the
sampler's LOD clamps alone, as on Vulkan, so the mip filter is always
set.
With max quality on, the frame dumps that change are the same 829 on
both backends, and match Vulkan's to within 41 pixels.
