    app: only use area dim., not off., for ui range of pixel-distance op props
    
    Don't offset the ui range of op properties that use pixel-distance
    units to the top-left corner of the region, since they're relative;
    only do that for pixel-coordinate units.  Let their ui range be
    [0, width/height].
