When I started this, I had originally drawn the ruler's ticks
and cursor in one JPanel contained in the JScrollPanel' HeaderViews,
but I got a lot of flicker when I moved the mouse in the MousePad
Component so I thought to overlay the Ruler JPanel with another
RulerCursor JPanel which I did but had other problems, so I switched
to RulerCursor Component - Andrew's advice fixed the alignment problem.

Seeing your response makes me think that paintComponent() is what I was
missing in the first place, so I think I'll go back and try MousePad
extends JPanel, Ruler extends JPanel and paints both ticks and cursor.

Thanks,
Jeff Higgins
