Chipp's alphatest (2)

[Graham Samuel]

I tried the test on MacOS 10.2.8 (Jaguar). It didn't work (the 
turquoise rectangle behind the right hand button didn't change). I 
noted that the AlphaData of the button was non-empty (didn't try to 
look at the contents). Since it's a button rather than an image, I 
don't know what that's supposed to mean (the TD suggests that only 
images can have AlphaData), but it may be of interest.
