Do you mean to say that ImageCanvas extends java.awt.Canvas, not
javax.swing.JPanel?  Then I understand why it works, but have to caution
that things do not work flawlessly everywhere.  At least in one instance,
AWT inside a Swing container did not work as expected: Linux with the
default window manager of GNOME (the repainting was sometimes correct,
sometimes not).
