[cairo] glitz

[Ignas B.]

Is glitz_set_rectangle the optimum way of drawing a rectangle in terms of
speed.
I tested it against simple gtk rectangle drawing  (with glitz_set_rectangle)
and the results were that the gtk application is
giving slightly faster drawing Could it be true that gtk is as fast as
opengl?
The thing is that its only trying to draw 2d primitive - rectangle. As i
imagine opengl does not give an acceleration for 2D primitives. Am i right?
