Wrap InstallColormap so that the DDX doesn't see colormaps from our ARGB
visual (avoids lovely green tint to screen). Also, set visual->nplanes
of ARGB visual to all used (including alpha) planes so DIX can set
pixel values correctly.
Translate automatic update regions correctly to account for borders
When nplanes == 32 (ARGB visuals), mask in all ones for alpha values to
allocated pixel values.
Remove redundant fbAddTraps declaration
Fix fbCopyWindow to work on non-screen pixmaps (not needed yet)
Replace broken clipping code with that from modular tree.
Respect subWindowMode.
