878 * fill=tile and a translucent tile is a "translucent" operation, whereas
879 * XDrawLine with fill=solid is an "opaque" one. Moreover themes can (and some
880 * do) intermix transparent and opaque operations which makes caching even
881 * more problematic.
882 * 2) Use Xorg 32bit ARGB visual when available. GDK has no native support
883 * for it (as of version 2.6). Also even in JDS 3 Xorg does not support
884 * these visuals by default, which makes optimizing for them pointless.
885 * We can consider doing this at a later point when ARGB visuals become more
886 * popular.
887 * 3') GTK has plans to use Cairo as its graphical backend (presumably in
888 * 2.8), and Cairo supports alpha. With it we could also get rid of the
889 * unnecessary round trip to server and do all the drawing on client side.
890 * 4) For now we draw to two different pixmaps and restore alpha channel by
891 * comparing results. This can be optimized by using subclassed pixmap and
892 * doing the second drawing only if necessary.
