1001 * work around this:
1002 * 1) Subclass GdkPixmap and cache translucent objects on client side. This
1003 * requires us to implement parts of X server drawing logic on client side.
1004 * Many X requests can potentially be "translucent"; e.g. XDrawLine with
1005 * fill=tile and a translucent tile is a "translucent" operation, whereas
1006 * XDrawLine with fill=solid is an "opaque" one. Moreover themes can (and some
1007 * do) intermix transparent and opaque operations which makes caching even
1008 * more problematic.
1009 * 2) Use Xorg 32bit ARGB visual when available. GDK has no native support
1010 * for it (as of version 2.6). Also even in JDS 3 Xorg does not support
1011 * these visuals by default, which makes optimizing for them pointless.
1012 * We can consider doing this at a later point when ARGB visuals become more
1013 * popular.
1014 * 3') GTK has plans to use Cairo as its graphical backend (presumably in
1015 * 2.8), and Cairo supports alpha. With it we could also get rid of the
1016 * unnecessary round trip to server and do all the drawing on client side.
1017 * 4) For now we draw to two different pixmaps and restore alpha channel by
1018 * comparing results. This can be optimized by using subclassed pixmap and
1019 * doing the second drawing only if necessary.
