[Gsl-shell-info] new GSL Shell release with graphics module

[Francesco Abbate]

Hi all,

I'm proud to announce the release 0.9.5 of GSL Shell. This new release
introduce a new powerful and flexible module to produce graphical
plots and diagrams.

The new module is very flexible and let the user produce almost any
kind of graphics to represent data or functions. The most basic usage
is just to plot a function or multiple functions but the most advanced
users will be able to do almost anything by using the powerful
graphical primitives.

The module is based on the excellent Anti-Grain Geometry (AGG) library
by Maxim Shemanarev.

You can find here the source code as well as a windows executable. In
order to test the software you can type:

> dofile('examples/plot.lua')
> dofile('examples/graphics.lua')

The basic documentation for the module is already available in the
website. You can find also a couple of examples.

The compilation with Windows is tricky and there is a bug in a mingw
library that will raise an error during the linkage. If you are
interested in compiling the code under windows please contact me
directly.

I'm sure that there are still a lot of problems and there are a lot of
features that should be added. As usual any suggestion or criticism is
welcome.

I'm also looking for volunteers so if you want to help don't hesitate
to contact the author.

Enjoy,
Francesco
