Torbjörn Andersson a18d4d5c2f Replaced drawLine() with a shorter version described in Wikipedia. It uses
a callback to plot each point so that it doesn't need to worry about how
the caller deals with screen dirtying, etc.

My plan is to move this function into a standard class. (That's why I used
the American spelling "color" instead of "colour".) I just haven't made up
my mind on which is the most appropriate one yet.
