Mouse Over on Radio button in SwingSet2 is unlike the native Mercury behaviour.
With the mouse over on a Radio Button or a check box , the label including the backgroubd turns blue in the native Mercury OS(Build 03). Where as only the label font color changes to blue in SwingSet2.

Steps to reproduce:
--------------------
1) Run the SwingSet2 Application on the Swing PIT build of 25th July with -Dswing.gtkthemefile=<Your gtkrc file location>. Change the LAF to GTK
2) Go to Checkbox demo.
3) Take the mouse over the check box.
4) Notice the color change of the Label font. (It turns to blue).
5) Now open any Native application with radio button or check box.
6) Take the mouse over the check box.
7) The Background color of the label changes to blue.

Note: The Linux flavour is SUSE 8 and Mercury build is 03
