It seems I don't even understand the problem you are trying to fix...

(I'm afraid I still don't understand the true meaning of
NumOfLines_partial.  This is not my best day, obviously.)

... and understand your solution even less.  What does the number of
*columns* have to do with it?  Maybe you meant lines_changed instead -
but that would also in general be wrong.

It seems you want more 'flicker', not less.  Making NumOfLines_partial
smaller can only have the effect of drawing lines again that have already
been drawn, as far as I understand.

Myabe it's a worthwhile goal, but it isn't "the fix" to what I was trying
to do, i.e. prevent unnecessary duplicate calls to display_page() for the
same lines.
