You were asking for a good value of DISP_OMEGA, that's at least what I
understood. My answer is -1, plus code changes.
That current_x can overflow is something completely different, IMO. But
now I'm cautious enough to ask what do you mean? Overflowing which
bound? I read this as integer overflow, integer = the data type.

The thing you implemented in set_iterator_to_next we talked about.
if (max_redisplay_ticks > 0)
update_redisplay_ticks (1, it->w);
I don't remember the offical name ATM.
