[Ruben Zilibowitz]

Hi,

Thanks for the reply. The Lines.hs example program seems to work just  
right. Unfortunately I still can't get colored lines to work in my 3d  
program. Maybe it has something to do with the fact my one is 3d and  
the example program is in 2d. Any other ideas? I would post some  
source code but there's quite a lot of code.
