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