Right. A simple (but inefficient) solution would be to add a d.erase
command at the beginning of the list.

It should be possible to set the canvas background colour with:

	.screen.canvas configure -bg <color>

The background should be re-calculated whenever a full redraw occurs,
e.g. if you change the zoom or click the redraw button.
