I was trying to get the right dimensions  reflected  when the painting 
full screen  preference is turned on. The PaintBoxMorph is scaled up on 
the OLPC and is slightly offscreen because of this. But to get its 
bounds after scaling is not straight forward because of the transformation.
Try this
morph := Morph new openInWorld.
morph extent => 50 at 40
morph scaleFactor: 2 (There is also a bug in scaleFactor: if the morph 
owner is nil )
morph extent => 50 at 40

This is complicates general code a bit as one must do all kind of 
contortions to get the right extent.
