Description Ralf Sternberg CLA 2010-12-28 11:55:54 EST 
SWT Widgets prevent illegal subclassing by means of the Widget#checkSubclass() method. This method is not effective in RAP due to historical reasons (Some illegal subclassing was unavoidable in the early days). From my point of view, we can and should now implement this mechanism properly.

To be revised:
* Display#isValidClass()
* Widget#checkSubclass() overrides in subclasses
