[GRASSGUI] graphic overlays

[Michael Barton]

This kind of negates the idea (I thought you were promoting too) of using
native GUI functions for all 'decorations'. It's not hard to add a layer
managers for d.grid, d.text, d.scalebar, etc. But it could clutter up the
main control more. 

What if we could make it scriptable using wxPython graphic elements?
