[cairo] _cairo_surface_fill_rectangles

[Guilherme Garcia]

Hi there,

I'm using libcairo and directfb as backend.
But libcairo seems to not use directfb backend's functions.
Especially when I draw a rectangule, libcairo calls  _cairo_surface_fill 
instead of _cairo_surface_fill_rectangles, and then, libcairo makes a 
fallback to draw the rectangle. Actually, I did't find any call to 
_cairo_surface_fill in libcairo's code.
I would like to know what can I do to make libcairo invoke 
_cairo_surface_fill_rectangles. Using the directfb backend's funtion 
DrawRectangle.

regards,

Guilherme
