Re: [PATCH 0/1] MR7179: wined3d: Add some DXT format mappings in the Vulkan renderer.

[Elizabeth Figura (＠zfigura)]

DXT1 should use the RGBA variant. See the relevant part of the spec [1]; we have volume_dxtn_test() in d3d9:visual, which you'll notice currently fails as it always emits 1.0 for alpha.
