Proposed patch

A public function is needed to set/update the size of a Quartz surface.  This
is because surface->extents is used in clipping calculations.  In GTK+, the
toplevel window is backed by a cairo surface.  If the toplevel window is
resized, the extents must be updated otherwise the clipping calculations will
not be correct and affect the drawing.

Patch is attached.
