1035 * work around this:
1036 * 1) Subclass GdkPixmap and cache translucent objects on client side. This
1037 * requires us to implement parts of X server drawing logic on client side.
1038 * Many X requests can potentially be "translucent"; e.g. XDrawLine with
1039 * fill=tile and a translucent tile is a "translucent" operation, whereas
1040 * XDrawLine with fill=solid is an "opaque" one. Moreover themes can (and some
1041 * do) intermix transparent and opaque operations which makes caching even
1042 * more problematic.
1043 * 2) Use Xorg 32bit ARGB visual when available. GDK has no native support
1044 * for it (as of version 2.6). Also even in JDS 3 Xorg does not support
1045 * these visuals by default, which makes optimizing for them pointless.
1046 * We can consider doing this at a later point when ARGB visuals become more
1047 * popular.
1048 * 3') GTK has plans to use Cairo as its graphical backend (presumably in
1049 * 2.8), and Cairo supports alpha. With it we could also get rid of the
1050 * unnecessary round trip to server and do all the drawing on client side.
1051 * 4) For now we draw to two different pixmaps and restore alpha channel by
1052 * comparing results. This can be optimized by using subclassed pixmap and
1053 * doing the second drawing only if necessary.
