If we're drawing to a luminance, luminance/alpha or intensity surface
we have to adjust (rebase) the fragment/quad colors before writing them
to the tile cache. The tile cache always stores RGBA colors but if
we're caching a L/A surface (for example) we need to be sure that R=G=B
so that subsequent reads from the surface cache appear to return L/A
We previously had a special case for RGB (no alpha) surfaces. This
change generalizes that for the other base formats.
Fixes https://bugs.freedesktop.org/show_bug.cgi?id=40408, but sRGB
formats are still failing. That'll be addressed in a later patch.
The fbo-blending-formats test isn't complete for sRGB yet and it's not
in all.tests for the very same reason. It might work with
GL_FRAMEBUFFER_SRGB disabled though, not sure.
Yeah, I looked at fbo-blending-formats and there's no sign of it
groking sRGB. It would be nice if the test would skip the srgb
formats until they're properly tested as I often run it manually and
would rather not see the invalid failures.
