Establishes a new clip region by intersecting the current
clip region with the current path as it would be filled by
fill() and according to the current
fill rule (see setFillRule()).
After clip(), the current path will be cleared from the
cairo context.
The current clip region affects all drawing operations by
effectively masking out any changes to the surface that are
outside the current clip region.
Calling clip() can only make the clip region smaller,
never larger. But the current clip is part of the graphics state,
so a temporary restriction of the clip region can be achieved
by calling clip() within a save()/restore()
pair. The only other means of increasing the size of the clip
region is resetClip().
