Hi,

	me again . . . just to re-iterate . . . I can just check the point
against the line my own way, but that is four subtractions and two divides per
line, and these lines aren't very big (and there's a lot of them), so I was
wondering if there were and routines actually in Allegro to do this. Just
thought I'd better clarify.
