ANNOUNCE: GENIUS 1.0.10 the "Back in Cali" release

[Jiri Lebl <jirka 5z com>]

Genius is a general purpose calculator with many advanced capabilities.
To find out more go to:
http://www.jirka.org/genius.html

You can now rename variables in the plots, plus a few other minor
enhancements and fixes.  Also require GTK 2.14 and GIO (dropped gnome-vfs)
if building the GNOME frontend.

In any case, Genius is one of the oldest GNOME projects, it has been the
original GNOME calculator before I got wild ideas about it doing absolutely
everything.  It is programmable, has a powerful language and handles many fun
features including support for matrices, rational numbers, and nice 2D and 3D
plotting.  The GUI version requires GNOME2 (at least glib2 if you don't want
a GUI) a recent enough GMP library and the MPFR library.  You can still use
the command line version if you prefer non-gui interface.

Here are the news in 1.0.10:

* Allow changing variable names for all plotting functions
* Add SlopefieldTicks, VectorfieldTicks, LinePlotVariableNames, and
  SurfacePlotVariableNames, parameters
* Add AskButtons interactive function
* CHANGE: spelling fix: AuxiliaryUnitMatrix doesn't have two l's
* Support for setting legend on LinePlotDrawLine with a "legend" parameter
* Allow comparisons (== and !=) with null, treating it as an empty matrix
* Uses GIO instead of GnomeVFS (Jan de Groot)
* Fix compilation without gtksourceview (thanks to Joe Sapp for pointing this
  out)
* Fix some crashes in plotting code
* Allow slopefield solutions to leave plot window by a small fudge factor.
* Fix zooming plots so that we can zoom by moving mouse in any direction
* Fix compilation with newer sealed vte (Vincent Untz)
* Fix up some typos in the documentation (Christian Kirbach, me)
* Translation updates (Christian Kirbach, Jorge González, Andrej Žnidaršič,
  Kjartan Maraas, Petr Kovar, Mario Blättermann, Fran Diéguez, Matej Urbančič,
  Andrej Žnidaršič, Marek Černocký, me)

* For some of the changes the author (Jiri) was partially supported by
  NSF grant DMS 0900885 and the University of Illinois at Urbana-Champaign

Genius is in Ubuntu, Debian, Fedora, GARNOME and probably other distribution
repositories, so check those.  Usually you wan to install two packages:
genius and gnome-genius (perhaps also gnome-common on some distros).  Of
course it will be a little bit before this version hits those servers ...

Have fun,

Jiri
