Jeff Muizelaar f2b12f7543 Bug 668921. cairo: Fix fixup_unbounded_boxes() to work even if the box is smaller than the extents. r=ickle
Currently fixup_unbounded_boxes assumes that the extents are tight when we only
have one box. This is not always true. e.g. when we tesselate boxes we can end
up with only one box which is smaller than the extents and the extents are not
updated.
