Then the opposite might happen.  A path with coordinates > MAX_FLOAT/2 
could be scaled down to be a reasonable size on the BufferedImage, but 
we'd have chopped out a lot of its geometry before it gets to the 
transform and comes back into range.

Again, that would only happen in the case of a stroke with a non-uniform 
transform, though...
