There should be two identical instances of the test visible side by side below, both shown inside of white rectangles.
The green and red rectangles should not stray outside the bounds of the blue rectangle (which is centered in the white rectangle).
The bottom two tests check for clipping to child and sibling Components. There should be two overlapping subComponents on each side. Click on either of the two children or the parent and just that one Component should repaint in a random color.
