You can send me these personaly and I will try to look at them (not before
January).

Nevertheless, for new forms of defined arrows, I show in
http://www.tug.org/applications/PSTricks/Mathematics/MathCurves-Ex1.tex
the standard way to define them - in this case ]-[

And for new fillstyles, I think that using `pst-fill' is the better way,
as it is very general and powerful. I suppose that only few people use it,
as there was no documentation available anywhere.

These last two months, I spend a lot of time to improve the macros and to
write an extensive documentation. First version is ready now and was just sent
it will be available in one week.

Thanks for your work. I had no PostScript error in my tests and sometimes it
seems to give good result. It's true that on other circonstances, results
seems strange. But it is not easy (at least for me) to understand the
PostScript code. I'll try to look at it more precisely later and also to think
generally to the problem. For some kind of curves, it seems easy (Thomas
Siegel implement in few lines a version of \psline which draw the arrow at the
end of each segment).
