AquaButtonUI.java now detects when html does not fit, and an implementation for alternate insets that are recursively tested for regular text inside layoutAndGetText() are now also being used for html content.

The test checks for red pixels on the edges of where the square image should be from the center of the button. The test fails with the non-changed jdk, but passes with the changes.
