[cairo-pattern] Extend infinite pattern extents to negative coordinates too

Browse source 
With things like meta-surface, the assumption that coordinates are always
non-negative make no sense.  Extend the "infinite" extents accordingly.

Also remove stale comment.  extents->width/height are unsigned these days and
cover the full range.
