make the "General" view option panel less Gaudi :-)

fixed crash when trying to extrude a discrete surface + minor mods in the faq

- removed all the crappy STL code and rewrote it using JF's POLY_rep
  class

- generalized POLY_rep so that we can use the polygonal discretization
  as a surface mesh, and mesh in 3D afterwards. I.e., we can now take
  an input triangulation (a single surface in STL format, multiple
  surfaces in STL format, one or more surfaces defined using the new
  "Discrete Surface" commands), and generate a 3D mesh that uses it. We
  could in theory even mix triangulated and "normal" surfaces in the
  same geometry, but nothing is done at the moment to ensure that the
  mesh at the interfaces would match (if it does, it actually works
  very nicely)

- new STL mesh output format to export a surface mesh as a STL file

- added an option to the GEO output routine to save the surface mesh
  as discrete surfaces associated with the geometrical surfaces

- added STL and Text output formats for post-processing views (the
  text output allows for example to exploit plugin-generated data in
  gnuplot)

- generalized Plugin(Evaluate):

  * can loop automatically over all the timestep and/or components

  * can do operations using data from an external view

     - if the 2 views are based on the same grid, the plugin does the
       evaluation very efficiently

     - if the 2 views are based on differenet grids, the plugin
       automatically interpolates the external view data onto the
       grid of the current view

- added new Rand() function in MathEval

- default colormap is now # 2 (the Matlab "Jet" colormap)

Small aesthetic changes:

- Only 'title-capitalize' window titles and menus; the rest should be
  capitalized like normal english sentences

- The window title should be exactly the same as the menu item
  (without the ellipsis character if there is one)

- 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!

'External data source' -> 'Data source'

typo

The new "External data source" option makes the "Vector type->Raised
view" unnecessary. Just select "Vector type->Displacement" and choose
the data source from any other view in the list--including "Self"!

added small option to color the arrows representing a vector field
according to the data from another view

- added a couple of entries in the FAQ
- inluded the FAQ in the texinfo manual
- merged README.gui in the texinfo manual

add an option to draw the post-processing scales horizontally + remove
Post_View.TransparentScales (never really worked well anyway)

make depend + update docs

- generalized vertex array class to use reallocatable arrays

- introduced vertex arrays in post for all triangles: this speeds
  things up tremendously for ALL scalar views: 2d scalar views of
  course, but also for 3d isos (tets, hexas, etc.) and all smooth
  normals. The costly computations (compute the isos, get the normals)
  are only done ONCE each time the view is changed. Then we just pass
  the vertex array to OpenGL everytime we need to redraw (e.g. when we
  rotate the scene)

- removed the display list code alltogether: it's completely blown
  away by the new vertex array code!

for the record: with the new drawing code, you can

- rotate 500,000 triangles in real time on a 3-year old linux PC
(tested with a boing 747 surface mesh from CU: 10 times faster than
old code)

- display and rotate in real time 10 transparent+smooth shaded 3D isos
for a 1 million tet mesh (about 1 frame per second with the new code;
took tens of seconds with the old one)

Awesome :-)

- removed the quads from the simplex trees (finally...)

  **warning**

  this is a pretty big patch that touches a lot of different files. I
  tried my best to update all the things that needed to be updated,
  but I probably forgot some things... Please test! (especially the
  export routines in obscure formats like SMS, Gref, etc., as well as
  the extrusion code)

- added second order edge vertices for hexas, prisms and pyramids
  (drawing not done yet)

- added sanity check for number of values in post-pro parsed file
  format

- merged all mesh printing/reading routines in Print_Mesh.cpp and
  Read_Mesh.cpp

- cleaned up the statistics code

New raster ("bitmap") PS/EPS/PDF output

Change the pronunciation joke. "People" take it far too seriously :-)

Add FreeBSD to the list of OSes on which the code is known to run.
