744 * do) intermix transparent and opaque operations which makes caching even
745 * more problematic.
746 * 2) Use Xorg 32bit ARGB visual when available. GDK has no native support
747 * for it (as of version 2.6). Also even in JDS 3 Xorg does not support
748 * these visuals by default, which makes optimizing for them pointless.
749 * We can consider doing this at a later point when ARGB visuals become more
750 * popular.
751 * 3') GTK has plans to use Cairo as its graphical backend (presumably in
752 * 2.8), and Cairo supports alpha. With it we could also get rid of the
753 * unnecessary round trip to server and do all the drawing on client side.
