Swt picture reflect

I am a big fan of Romain Guy and i really like the swing demo he provides.
So today i tried to write the SWT equivalent to its swing reflection.
Since the SWT GC is not as advanced then the swing/java2d i could not use the alpha gradient like him.
Anyway using tips described in the SWT image article it was quite easy.

In fact it work with black background but if i change background color the result is buggy.


If there is an SWT image expert in the room, help will be appreciated.

Source code is here, webstart demo is on its way...
