909 * 1) Subclass GdkPixmap and cache translucent objects on client side. This
910 * requires us to implement parts of X server drawing logic on client side.
911 * Many X requests can potentially be "translucent"; e.g. XDrawLine with
912 * fill=tile and a translucent tile is a "translucent" operation, whereas
913 * XDrawLine with fill=solid is an "opaque" one. Moreover themes can (and some
914 * do) intermix transparent and opaque operations which makes caching even
915 * more problematic.
916 * 2) Use Xorg 32bit ARGB visual when available. GDK has no native support
917 * for it (as of version 2.6). Also even in JDS 3 Xorg does not support
918 * these visuals by default, which makes optimizing for them pointless.
919 * We can consider doing this at a later point when ARGB visuals become more
920 * popular.
