[Mesa-dev] [PATCH 2/3] i965: Add B8G8R8X8_SRGB to the alpha format override

[Neil Roberts]

brw_init_surface_formats overrides the render format for RGBX formats
which aren't supported for rendering so that they internally use RGBA
instead. However, B8G8R8X8_SRGB was missing so it wasn't marked as a
renderable format. This patch just adds it.

This might conflict when ported to the 11.x branches because the code
above doesn't have the if statement there. It should be fine to add it
without the if statement on those branches although it shouldn't
matter if it does have it either.
