861 * XDrawLine with fill=solid is an "opaque" one. Moreover themes can (and some
862 * do) intermix transparent and opaque operations which makes caching even
863 * more problematic.
864 * 2) Use Xorg 32bit ARGB visual when available. GDK has no native support
865 * for it (as of version 2.6). Also even in JDS 3 Xorg does not support
866 * these visuals by default, which makes optimizing for them pointless.
867 * We can consider doing this at a later point when ARGB visuals become more
868 * popular.
869 * 3') GTK has plans to use Cairo as its graphical backend (presumably in
870 * 2.8), and Cairo supports alpha. With it we could also get rid of the
871 * unnecessary round trip to server and do all the drawing on client side.
872 * 4) For now we draw to two different pixmaps and restore alpha channel by
873 * comparing results. This can be optimized by using subclassed pixmap and
874 * doing the second drawing only if necessary.
