Currently we spend some effort to figure out which part of the screen needs
a redraw. This computation costs time.
I think removing all that clever code might yield a speed up because we
would not spend the time for this computation.
You say I could try it out by setting NEED_REDRAW(?sp).
Ok, the effect of both is obviously a full redraw.
The question is, whether setting NEED_REDRAW means that there is almost
no time spend for the computation of what needs to be redrawn (because e.g.
the code looks like
if (!NEED_REDRAW)
fancy_computation();
), or whether this mean we would spend the same time for the guessing
_plus_ the time for the full redraw.
