Just a little up date on this; I've pushed a commit that changes the
gtk_paint_* API to take a cairo context rather than a GdkWindow. This
clearly breaks all widgets and so although it compiles, it won't run in
any shape or form.

I'm a bit undecided on how to proceed next. I could go through every
single use of gtk_paint_* in GTK+ and update it to the new API. However,
this will be somewhat tedious and lengthy task, and if we want to change
the API further (such as remove the GtkWidget pointer), I'd have to this
all over again.

Any thoughts would be welcome.

Thomas
