old_clip = gstate->clip;
_cairo_clip_init_copy(&clip, &gstate->clip);

rectangle.x = rectangle.y = 0;
rectangle.width = w;
rectangle.height = h;
status = _cairo_clip_rectangle(&clip, &rectangle);
gstate->clip = clip;
...
gstate->clip = old_clip;

would be cheaper.

But having typed that one can see the immediate reason for not doing so.
