backends must implement a canvas that handles connections for
'button_press_event' and 'button_release_event'. See

This is where you actually build the GUI widgets (called by
__init__). The icons home.xpm, back.xpm, forward.xpm,
hand.xpm, zoom_to_rect.xpm and filesave.xpm are standard
across backends (there are ppm versions in CVS also).
You just need to set the callbacks
home : self.home
back : self.back
forward : self.forward
hand : self.pan
