    svp clipping: Rectangle dimensions don't map directly to B2IBox.
    
    Previously the clip region would end up being 1 pixel smaller in both
    directions than the requested area -- B2IBox considers the bottom-right
    point to NOT be included in its area, whereas Rectangle considers the
    bottom-right point to be the last point WITHIN its area.
    
    (This is equivalent to the Rectangle's getWidth/GetWidth differentiation.)
    
    This is noticeable e.g. with tiled rendering, where images spanning
    a tile boundary are clipped to paint only the region within a given
    tile -- however previously they would be clipped by an additional pixel
    in each direciton, resulting in an empty border along the bottom-right
    edge.
