Added a new shader aswizlle_prog to wired the alpha to 1 when
the image color depth is 24 (xrgb). Then we don't need to fallback
the xrgb source/mask to software composite in render phase. Also
don't wire the alpha bit to 1 in the render phase. This can get
about 2x performance gain with the cairo performance trace's
firefox-planet case.
