Theoretically, we could use it to support UYVY and YUY2 *textures* as well, but it would still require converting from YUV to RGB after sampling.

That introduces new warnings though:
.../dlls/wined3d/arb_program_shader.c:7634:9: warning: enumeration value ‘COMPLEX_FIXUP_YUV’ not handled in switch [-Wswitch]
