Indeed I am completely sure that all the calculations can be done by a
macro,include,...
I got the idea for the splines from a quite tricky include file

same as my compile. But there are reasons to use the custom compile. It is
about 1000 times faster (which is not a real reason if you are using only
one or two splines with a few control points) and it is MUCH easier to use.

happy tracing
