is it possible to cut a cairo_t B out of another cairo_t A?
For example, I plot something to cairo_t A and then give this cairo_t A
to another plotting routine, which should only be able to plot to a
cut-out of this cairo_t A.
I can call the routine with x and y coordinates, a width and a height of
the allowed area to plot to, but I want to ensure that the routine is
only able to plot to the cut-out. So it would be more secure to give
only a cut-out of cairo_t A to the routine, not the entire cairo_t A.
Is there any function in Cairo which cuts an area out of a cairo_t A and
returns this area as a cairo_t B?
