This fixes a small but annoying painting issue that happens if some
components are invisible. Also, I removed some useless 'optimization'
from repaint() that caused unnecessary creation of Rectangle objects.

* javax/swing/JComponent.java
(paintChildren): Also check for the visibility of a child
component
to avoid artifacts.
(repaint): Simply add this component to the RepaintManager rather
than
trying to do useless optimization here.
