    [pattern] Fix up OBO introduced to cloned area
    
    In the midst of porting 5eec3e378afd6ff9991cea8e42b8478eb3e79773 I failed
    to include the pad in the floor() and ceil() which introduces two
    potential off-by-one errors into each dimension of the region of interest
    of the source surface.
