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