42ebe3dfd9b0803913e0d932909ca5872d937c20 is the first bad commit
commit 42ebe3dfd9b0803913e0d932909ca5872d937c20

    mesa/st: add support for EXT_texture_swizzle.
    This passes on r300g, the only bit I'm not really sure about is the handling
    of the sampler_view in st_atom_texture.c, I unreference it there if the swizzle
    value changes and I also have to create a new set of functions to create a new
    one since the u_sampler.c ones don't handle swizzle so much.
    adds r300g + softpipe enables, I think other drivers could pass easily enough.
