Use XLIB_SKIP_ARGB_VISUALS environment variable to disable all depth 32

visuals. Necessary to keep Flash from crashing.
Must call ValidateGC/ValidatePicture on "real" GC/Picture to ensure
    pCompositeClip is set correctly.
Need to take the composite clip from the "real" GC/Picture and turn it into
    the clientClip for the backing version.
Adjust pixmap screen origin to account for drawable->x/y Change debugging
    output a bit (disabled by default)
