make the EigSolve interface allow for the solution of eigenvalue problems
of arbitrary size (instead of limiting to 3x3)

new plugin to compute the principal values of a tensor field

new self-contained eigenvalue/eigenvector routine (translated from eispack)

complete JF's FindCubicRoots routine (complex roots)

- Moved all the Raise[][] stuff out of the drawing routines, and into
  Graphics/Post.cpp

- New 'generalized raise' mode (can use arbitrary expressions, possibly
  with external data sources, to raise/offset views dynamically). Original
  patch by Nicolas Tardieu. Merci Nico!

Support for TCP/IP sockets (permits to launch solvers on remote hosts).
Thanks to C.Stott@surrey.ac.uk for the original patch.

- moved the AdaptiveView stuff in its own header file

- fixed small bug in IsoSimplex (when Raise != 0)

- fixed small memory leak in Plugin/Extract (when one or more
  expressions are invalid)

fix help string

- fixed CTX.post.list error in new plugins

- cleanup integrateLevelsetPositive in Integrate.cpp

- re-indent

- Added a bunch of colormaps from:

  Color Theory and Modeling for
  Computer Graphics, Visualization,
  and Multimedia Applications

- Increased max size of colormap to 1024

- Small cleanup in parser+plugin

This patch fixes an old design flaw in the post-processing module,
namely that we used a list of Post_View objects instead of a list of
pointers to Post_View objects in CTX.post.list.

This had many annoying consequences, in particular the fact that we
needed to be extra careful every time the list was reallocated (as
pointers to the list elements would become invalid).

I tried very hard to change the code everywhere it should be changed,
but I might have missed something. Please let me know if you see
anything suspicious (like a crash when you duplicate/remove/combine/...
post-processing views).

fixed FPE in computeLevelsetPositive when SUMABS=0 (still not sure what
this stuff is useful for, though :-))

Use the new Fl::delete_widget() call to delete widgets in callbacks
in FLTK 1.1.6. FLTK 1.1.5 introduced a potential crash due the fact
that it could access a widget's data after its callback was executed.
Fl::delete_widget() in 1.1.6 delays the deletion until the next
Fl::wait() call. In any case, this means that we cannot use
group.clear() anymore.

make Export_LcField also work with SimplexBase

better solution for offset

fine-tune epsilon

better epsilon

update to latest gl2ps

fixed error checking code to work also with adaptive views.

The "Simplex" class is now derived from a new class "SimplexBase",
which contains only pointers to the nodes, and none of the other stuff
necessary for the actual mesh generation.

All the input/output/display routines have been rewritten in terms of
SimplexBase: this provides a gain of almost 50% in memory when you
just load meshes from .msh files to do visualization stuff, instead of
actually generating the mesh.
