> 1) Launch the kitchen sink demo in the desktop application context
> 2) Expand the tables section such that the table is only half-visible
> 3) Scroll the table up and down
> Result: paint artifacts appear.  See attached screenshots.  It appears that the graphics.copyArea() call is only taking into account the scroll pane's viewport bounds, not  cross-referencing the scroll pane's visible area.
