I had profile_time'd this demo earlier, and found that
96% of the time was spent, not in sorting, but rather 
in the Watcom DOS routine for drawing line segments. 
I had also noticed that it ran much faster when 
translated/compiled with DJGPP + Allegro (sorry, no exact timings).
Anyway, the demo now runs *much* faster (5.7x) with Open Watcom 1.4
than with the old Watcom 10.6. I measured the ex.exe interpreter,
but the translator shows a similar, perhaps a tad better,
speed-up. This speed-up will likely affect some other DOS graphics 
programs, but I wouldn't expect a big speed-up on typical programs. 
I'll do some more benchmarking soon.
