939 * We should somehow handle translucent images. GTK can draw to X Drawables
940 * only, which don't support alpha. When we retrieve the image back from
941 * the server, translucency information is lost. There're several ways to
942 * work around this:
943 * 1) Subclass GdkPixmap and cache translucent objects on client side. This
944 * requires us to implement parts of X server drawing logic on client side.
945 * Many X requests can potentially be "translucent"; e.g. XDrawLine with
946 * fill=tile and a translucent tile is a "translucent" operation, whereas
947 * XDrawLine with fill=solid is an "opaque" one. Moreover themes can (and some
948 * do) intermix transparent and opaque operations which makes caching even
949 * more problematic.
950 * 2) Use Xorg 32bit ARGB visual when available. GDK has no native support
951 * for it (as of version 2.6). Also even in JDS 3 Xorg does not support
952 * these visuals by default, which makes optimizing for them pointless.
953 * We can consider doing this at a later point when ARGB visuals become more
954 * popular.
955 * 3') GTK has plans to use Cairo as its graphical backend (presumably in
956 * 2.8), and Cairo supports alpha. With it we could also get rid of the
957 * unnecessary round trip to server and do all the drawing on client side.
958 * 4) For now we draw to two different pixmaps and restore alpha channel by
959 * comparing results. This can be optimized by using subclassed pixmap and
960 * doing the second drawing only if necessary.
