True; I wasn't thinking of GtkStyle and the dependency on the theme in
use.  What I mainly meant was that Gtk doesn't quite fit the bill
(yet) for what the original poster was looking for, since Gtk still
supports drawing through a non-cairo path.

Speaking of GtkStyle.. it's really too bad there's no way to hand
GtkStyle a cairo_t to draw with (with some transformation matrix
already set), instead of having all the functions create their own
cairo_t from the GdkWindow.
