Re: drawing functions, thick lines

[Greg Lutz]

It's actually a fairly complex problem.  There's a seminal academic paper 
on it from some time in the 80's that treats wide lines, including their 
joints, as general two-dimensional areas, and deals rigorously with 
questions about which pixels should be included and which excluded. I think 
some modern operating system graphics systems base their wide-line-drawing 
APIs on this work.

You can easily simulate a thick line by two lines:

Line(x1  ,y1  ,x2  ,y2  )
Line(x1+1,y1+1,x2+1,y2+1)
Thanks, that should do it for now. Could have thought of that myself.
Hmm, silly me. Doesn't work. It always depends on the direction, so in 
some direction the lines overlay, in other directions they have spaces 
between them.
