I don't like that approach because getVisibleRect() is used by the Swing
internals.  It should always return a value in the system coordinates.

I advocate going back to the problem(s) that resulted in the addition of the
setGraphicsOrigin method in the first place and trying to determine another
solution.

Barring that, rather than tweaking the coordinates in getVisibleRect(), how
about adding a SequencePanel specific method to do this?
