1012 * work around this:
1013 * 1) Subclass GdkPixmap and cache translucent objects on client side. This
1014 * requires us to implement parts of X server drawing logic on client side.
1015 * Many X requests can potentially be "translucent"; e.g. XDrawLine with
1016 * fill=tile and a translucent tile is a "translucent" operation, whereas
1017 * XDrawLine with fill=solid is an "opaque" one. Moreover themes can (and some
1018 * do) intermix transparent and opaque operations which makes caching even
1019 * more problematic.
1020 * 2) Use Xorg 32bit ARGB visual when available. GDK has no native support
1021 * for it (as of version 2.6). Also even in JDS 3 Xorg does not support
1022 * these visuals by default, which makes optimizing for them pointless.
1023 * We can consider doing this at a later point when ARGB visuals become more
1024 * popular.
1025 * 3') GTK has plans to use Cairo as its graphical backend (presumably in
1026 * 2.8), and Cairo supports alpha. With it we could also get rid of the
1027 * unnecessary round trip to server and do all the drawing on client side.
1028 * 4) For now we draw to two different pixmaps and restore alpha channel by
1029 * comparing results. This can be optimized by using subclassed pixmap and
1030 * doing the second drawing only if necessary.
