Try to avoid adding single purpose functions to the general surface
layer. At that level, we should only have functions that apply to all
types of raster and paginated surfaces.

It looks like we could achieve the desired effect with the check pushed
down into _cairo_gl_spans_compositor::copy_boxes(). So I pushed a
different patch, can you please look it over.

Thanks for the couple of patches,
-Chris
