705 * do) intermix transparent and opaque operations which makes caching even
706 * more problematic.
707 * 2) Use Xorg 32bit ARGB visual when available. GDK has no native support
708 * for it (as of version 2.6). Also even in JDS 3 Xorg does not support
709 * these visuals by default, which makes optimizing for them pointless.
710 * We can consider doing this at a later point when ARGB visuals become more
711 * popular.
712 * 3') GTK has plans to use Cairo as its graphical backend (presumably in
713 * 2.8), and Cairo supports alpha. With it we could also get rid of the
714 * unnecessary round trip to server and do all the drawing on client side.
