Hi

I found that standard GGI line clipping getting perpetual loop with some
arguments. It was while using these arguments: 568, 383, 49360, and 1234 for
clipping area 100, 3, 1019, 766. May be it was different because I found it
written in my notebook but sure only for 90%. Anyway it was close enough. It
happened because of overflow in line formula.
Solution is: just break the perpetual loop. It's not necessary there.
Also I found that Matrox G100 acceleration is slowly than software drawing.
That's it.

Best Regards, Dmitry Semenov

        What do you refer to with GGL? :)
