This test is only for composition, but what about the pattern images ? 
The "filling patterns"  you are talking about, is setting an image to
a color and then fill something with this color, right ?
 
I'm asking because when I profiled Camaelon, pattern filling was one
of the thing that took lots of time, and i'm hoping that by having the
possibility to use filling pattern directly it will be faster (as you
shouldn't need context switching during the filling).

And, does it properly follow the current path mask ? (actually I think
that doesn't work on xlib, only with art, anyway...)
