When would an object do this without being passed or holding some other ui 
object that gives it context? A button doesn't draw on the screen, it draws 
within some containing thing, etc, recursively. At least this is how it 
works in every ui toolkit I'm familiar with (including AWT, Swing, SWT). 
Could you give an example that I could understand without learning Morphic?
