After fixing #6826074 there are still a few issues with painting hw components inside Swing,
please see the attached image with a cropped JButton.

It is believed that now Swing correctly validates the components after moving/resizing
so this is addressed to AWT.

Please use the test from 6826074 and 6778882

Run the test case from 6826074, scroll the JScrollPane back and forth
and see the painting artifacts on the button.

Reproduced on the latest JDK 7.
