[Mesa-dev] r300g + mesa/st support for EXT_texture_swizzle

[Corbin Simpson]

Why do we need any caps for this? Unless I read the spec wrong, this is a
mere SWZ following the affected texture lookup, in the worst case.

I think it is worthwhile to keep the format swizzle orthogonal to the
sampler view swizzles. It is actually more complex trying to describe
swizzles in terms of the packed vector, since they not always have
unambiguous meaning (bitmasks, subsampled formats, compressed textures).
