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