yes, but since my math skills aren't much better than basic, all those
equations and polynomials mean nothing to me. unless I get a clear
equation (like the cubic one I used, which I found in another site), I
can't go any further.
if anyone wants to translate those funny drawings for me into something
comprehensible, I'll put it in the patch.

my purpose of doing this is basically to "modulate" a [line] (0-1), that
is, with one direction. I never worked with higher than cubic curves
(coreldraw etc are cubic), but since the purpose is to have a line that
follows only one direction, would it become that unpredictable?

I know. that's another thing I have to look at in the future, but don't
have a) the time and concentration b) the necessity for it. although it
would be better, because then the patch would be "complete".
