[TeXmacs] Nouveau plugin TeXgraph.

Hello everybody,

I just wrote a plugin for TeXgraph. This software makes it possible to create graphs which will be used inside LaTeX (you can find this really good software in French at http://texgraph.tuxfamily.org/index.html).
I followed the help files to create two files :
- tm_texgraph based on tm_pstricks by Nicolas Ratier
- init-texgraph.scm based on init-eukleides.scm by Joris van der Hoeven.
To use it, you have to extract texgraph.tar.gz in the "~/.TeXmacs/plugin" directory under linux and to install TeXgraph of course.

As it is my first attempt to do something like this, it is not clean and seems buggy.
There are a few things I can't correct. For example, in the following TeXgraph session in TeXmacs, I can't remove the red <\errput> just below the graph.

<\output>
<with|mode|math|T<rsub|E>X*g*r*a*p*h>
TeXmacs interface to TeXgraph.
Defaut : Fenetre(-4+3*i,4-3*i,1+i), Marges(0.25,0.25,0.25,0.25)
</output>
<\input|TeXgraph] >
Marges(0.25,0.25,0.25,0.25),size(7.5),\

So your comments would be very welcome.
And as it is my first post on this forum, thank you for this great software that I discovered 2 years ago.


Bye.
