Viewport background color does not update along with other user preferences

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Open a new graph window.
2. Select Help > Preferences... from the main window.
3. Select the Appearances tab.
4. Change the Background colors in the Graph colors section.
5. Click Apply.
6. Note that the viewport background only changes for new graph windows.

What is the expected output? What do you see instead?
  Everything else is refreshed and repainted.  Why not the viewport background (possibly because the background color for the viewport's Graphics2D object is not set with each rerender?)
