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