Description Rüdiger Herrmann CLA 2011-01-17 08:44:44 EST 
The constructor to create an empty image of a given size is missing in RWT.
Typically, this constructor is used to create images that are drawn upon by creating a GC:
  Image image = new Image( device, width, height );
  GC gc = new GC( image );
  gc.drawRectangle( 0, 0, 50, 50 );
  ...

Image(device,width,height) constructor and test cases

Calling the constructor creates an image of the given width and height with all pixels set to white.
Comment 2 Ralf Sternberg CLA 2011-01-22 11:00:15 EST 
Even though this constructor is useless without GC support for Images, I think there's no reason to hold back a correct implementation.
Applied patch to CVS HEAD.
