The current disussion about circles made me think about something else
in the same genre. How do you, efficiently, draw lines, arcs, circles
and so on with a line width bigger than 1?

Although I have read many articles about fast line and circle drawing
algorithms, I have never seen anything about thicker ones.  Neither
have I seen any algorithms in any computer graphics books. I find this
a bit strange since such algorithms seem to me to be very important.
An obvious example is in a laser printer.

Could somebody please explain how this is done, or give me some
pointer to where I can find the information?
