I forgot to commit these last week: it's just the beginning of some
cleanup of the old 2D algorithm (removed non-functional voronoi
insertion, fixed a couple of memory leaks, added some comments, etc.)

added some FIXME comments

- added a couple of keywords
- removed adapation stuff in the intro

Fixed '//' with EOF before '\n' bug

removed border=0 attrbute so that the page actually validates

simplified Draw_Cylinder

small copy & paste bug (we tested Tree_Nbr(Points) twice instead of Tree_Nbr(Points)
and Tree_Nbr(Vertices))

better shift+a: show the menu window *after* the opengl window

fuck, missed an #ifdef USE_FLTK for the non-gui version

typo

The fltk folks finally fixed the ctrl+n/ctrl+p/... bug, so we can use
ctrl+n for new file now.

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

missed this one

And more airplane work!

- merged STL patch from Nicolas Tardieu. This patch permits to
  create an real elementary surface for each STL face. Until
  we have some code to directly remesh the STL data (which would
  be much nicer and cheaper), this is very useful. We can finally
  use STL representations to create meshable volume models.
  Thanks Nicolas !

- new option to color the mesh by physical entities (if an element
  belongs to multiple physicals, we use the first one)

- additional cleanup of the mesh drawing code

- big cleanup of the geometry creation section in the parser:

  * removed horrible Geo/DataBase.cpp
  * fixed all List-related memory leaks (a lot!)
  * added tests to check if we don't try to recreate existing
    entities (this should prevent many weird bugs due to incorrect
    input files)

- fixed LineLoop/EdgeLoop memory leaks

- many small fixes all over the place

test view_numer < #list for shift+w

use the 3d arrows by default

- Added shortcut (shift+w) to access the options of the current view
- minor tweaks for earlier commit (made 3D arrows the default in
  non-postpro things, etc.)

fixed couple of warnings

More "airplane" work...

- rewrote the way we handle lights: glEnable(GL_LIGHTING) is now used
  at the lowest level, where it belongs. This fixes many lighting
  glitches, and should make the whole stuff much more predictable;

- simplified the display modes for geometry and mesh: the choice
  between wireframe/solid is now independent of the choice of
  lighting/no lighting (and there is a new "Enable lighting" option
  for the geometry, too--even if it does only affect things like
  normals/tangents at the moment);

- brand new code to draw really nice (shaded) 3D arrows + 3 options
  that fully parameterize them (they can degenerate into pyramids,
  cones, w/ or w/o stems, etc.);

- new options so that we can also use the new arrows outside the
  post-processing module (e.g. for tangents/normals).

- "alt+d" now simply switches between solid and wireframe mode;

- new shortcut "alt+w" to switch the lighting mode for all the modules
  (geo/mesh + all post views) at once.

bring option docos up-to-date

Update copyright notice

fix about window position

Save position of solver and context windows

Create temporary and error files in home directory to avoid file
permission issues (most notably on Mac OS X, when launching Gmush
from the Finder)

Fixed (or added a FIXME comment) when a post.list reallocation
could lead to problems

better -convert

better -convert

Added "append" argument to WriteView (so that "gmsh -convert file file"
can handle all the views in the input file and not only the first one).

Fixed another race condition problem in combine_timestep (when removing the
original views)

small changes to copy the time values (instead of relying on EndView
to just add the time step number)

This seems to fix the crash Laurent experiences with combine_timesteps
(but I don't understand exactly why).

New syntax bit: you can now use #aa[] to get the size of the list aa[]

typo buglet

Link -> Links

Following a discussion with Laurent, we can now combine multiple views
(under certain conditions) into multi time step ones. This permits e.g.
to output separate .pos files for each time step, and still have a real
time evolution in gmsh. Pretty neat :-)

Fixed race condition for RemoveView

New post-processing range mode to adapt the scale for each time step (i.e.,
min/max is time step dependent)
