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)

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).

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

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 :-)

Removed extra arg in Init_Mesh

remove tMesh

new "Delete All;" command + only warn when reloading duplicate geometry
points.

- Slightly reorganized the visibility browser window (the "toggle"
  behaviour in the input field was confusing)

- added Show and Hide commands in the parser to enable scripting of
  the visibility stuff

- Moved Visibility.{cpp,h} into Common/ to avoid dependencies with the
  Graphics library in the parser

Fixed missing exception handling for PluginManager::action() (this led to
a crash when General.DefaultPlugins==0).

- new DecomposeInSimplex plugin
- new "Combine Views" command in the parser
- cleaned up View::tranform and View::smooth (+small bug fix for SLs)
- better check for transparency sorting
- make depend
- new View.AlphaChannel option to change the transparency
  globally for a given view (instead of having to change the colormap
  by hand every time)

With all the above, we can now generate very nice (and correct)
transparent iso-surfaces:

Merge "../tutorial/view3.pos";

minIso = 0;
maxIso = 2;
nbIso = 7;

Plugin(CutMap).iView = 0;

For i In {1:nbIso}
  Plugin(CutMap).A = (maxIso-minIso)/nbIso * i;
  Plugin(CutMap).Run;
EndFor

Delete View[0];
Combine Views;

For i In {1:nbIso}
  Delete View[0];
EndFor

Plugin(DecomposeInSimplex).iView = 0;
Plugin(DecomposeInSimplex).Run;

View[0].AlphaChannel = 0.6;

Cleaned up the whole Include/Merge/Open mess (removed the ugly
yyin/yyname tables in the parser, made the Merge routine reentrant
+ uniformized all the INFO/STATUS messages).

This should fix a nasty side effect from this morning's
commit (wrong yynames when doing multiple merges in the same
file).

Make Merge/Save/Print/Open behave like Include, i.e., open the file in the
same directory as the main project file (if the path is relative).

Forgot these

Big Levelset rewrite (+ cleanup of all other plugins).

Not finished yet, but I need to commit this now so that I can use it
with the boss tomorrow at work.

This version should compile and have all the old features working,
plus some extras (levelsets of scalar/vector/tensor 1D, 2D and
3D simplectic views).

JF: 'Plugin(XX).Save' is now deprecated. Use 'Save View[XX] "filename"'
instead.

Fix 2 gcc warnings

- Fix pb with index returned by Extrude Surface
- Upgrade gl2ps

remove warnings for now

Fix + generalize index retrival for geometrical transformation

- Comment JF's last changes in the parser until we fix the syntax

- Update gl2ps

- Small fix in the configure script to better detect fltk-config

- Fix Parser/Makefile (for older versions of bison)

Add 'newl' (synonym for 'newc') and fix the docs

Speed up variable creation/retrieval by replacing 'List_T *Symbols_L'
by 'Tree_T *Symbols_T'.

Fix includes with absolute paths

sync laptop and acm machine

Fix whitespace in copyright headers

Add Layer on Extrude Point (phase 2 -- remove duplicates)

Added Layer option for Extrude Point

Make headers self-contained

Add add these, too.

Clean up VERSION_FLAGS and OS_FLAGS (use HAVE_FLTK instead of _FLTK,
remove _BLACKBOX, etc.)

bump version to 1.37.0: system calls on Windows are now correctly implemented using the CreateProcess Windows API

Updated copyright

box of e.g. a view when merged in a script

Simplify error messages in parser a bit and change msg from ERROR to WARNING for list of shapes (less annoying when doing generic transformations, e.g. of points). Noticed this thanks to Genot Jean-Sebastien <JSGenot@HerouxDevtek.com>
