Issue #1795 - Add closure point to bounds calculation.

This addition of a closure point (explicitly completing the closed shape) isn't
strictly needed in our current cairo version as it works perfectly fine without,
but if our clipping extents code changes then this might cause problems if the
extra point isn't added (in case of 0-length paths).
