I thought about implementing that by myself some time ago (after doing the 
client side blending), but then I saw that Qt 3.0 will do that by itself (and 
it already does in the snapshots) so I think there's no need to implement 
XRender based blending in kdelibs (in fact, the current classes for alpha 
blending should go away when we change to Qt 3.0 as I suppose that Qt already 
implements a client-based blending when X11 doesn't have a Render extension)
I suppose Bradley could correct me if I'm wrong.

Sorry,
