How to paint a background and place graphics on top of if?

Hi Sarah and Ben,

ok, I wasn't very clear:

- I want to PAINT, not DRAW by script; using graphics is not possible 
because there would be too many objects, making scrolling and dragging 
too slow, so I want to create a "background" picture instead. I don't 
find out how use the paint tools in  a script.

- at times I want to repaint portions of the picture (because I don't 
have graphic objects); it would be easy if I had soemthing like a 
cliptrect which helps me limit the painting to just that portion.

The second is not so essential because I can replace cliptrect with a 
bit of thinking. But the painting thing is a pure mystery to me, still.
