New in 1.16: Added single/double buffer selection (only useful for
Unix versions of Gmsh run from remote hosts without GLX); fixed a bug
for recent versions of the opengl32.dll on Windows, which caused OpenGL
fonts not to show up;

New in 1.15: Added automatic visibility setting during entity
selection; Corrected geometrical extrusion bug;

New in 1.14: Corrected a few bugs in the GUI (most of them were
introduced in 1.13); Added interactive color selection; Made the
option database bidirectional (i.e. scripts now correctly update the
GUI); Default options can now be saved and automatically reloaded at
startup; Made some changes to the scripting syntax
(PostProcessing.View[n] becomes View[n]; Offset0 becomes OffsetX,
etc.); Corrected the handling of simple triangular surfaces with large
characteristic lengths in the 2D isotropic algorithm; Added an ascii
to binary post-processing view converter;

New in 1.13: Added jpeg output on Windows;

New in 1.12: Corrected vector lines in the post-processing parsed
format; corrected animation on Windows; corrected file creation in
scripts on Windows; direct affectation of variable arrays;

New in 1.11: Corrected included file loading problem.

New in 1.10: Switched from Motif to FLTK for the GUI. Many small
tweaks.

New in 1.00: Added PPM and YUV output; Corrected nested If/Endif;
Corrected several bugs for pixel output and enhanced GIF output
(dithering, transparency); Slightly changed the post-processing file
format to allow both single and double precision numbers.

New in 0.999: Added JPEG output and easy MPEG generation (see t8.geo in the
tutorial); Clean up of export functions; small fixes; Linux versions
are now compiled with gcc 2.95.2, which should fix the problems
encountered with Mandrake 7.2;

New in 0.998: Corrected bug introduced in 0.997 in the generation of
the initial 3D mesh;

New in 0.997: Corrected bug in interactive surface/volume selection;
Added interactive symmetry; Corrected geometrical extrusion with
rotation in degenerated or partially degenerated cases; Corrected bug
in 2D mesh when meshing in the mean plane; 

New in 0.996: Arrays of variables; Enhanced Printf and Sprintf;
Simplified options (suppression of option arrays).

New in 0.995: Totally rewritten geometrical database (performance has
been drastically improved for all geometrical transformations, and
most notably for extrusion). As a consequence, the internal numbering
of geometrical entities has changed: this will cause incompatibilities
with old .geo files, and will require a partial rewrite of your old
.geo files if these files made use of geometrical transformations. The
syntax of the .geo file has also been clarified. Many additions for
scripting purposes. New extrusion mesh generator. Preliminary version
of the coupling between extruded and Delaunay meshes. New option and
procedural database. All interactive operations can be scripted in the
input files. See the last example in the tutorial for an example. Many
stability enhancements in the 2D and 3D mesh algorithms. Performance
boost of the 3D algorithm. Gmsh is still slow, but the performance
becomes acceptable. An average 1000 tetrahedra/second is obtained on a
600Mhz computer for a mesh of one million tetrahedra. New anisotropic
2D mesh algorithm. New (ascii and binary) post-processing file format
and clarified mesh file format. New handling for interactive rotations
(trackball mode). New didactic interactive mesh construction (watch
the Delaunay algorithm in real time on complex geometries: that's
exciting ;-). And many, many bug fixes and cleanings...

New in 0.992: corrected recombined extrusion; corrected ellipses; added
simple automatic animation of post-processing maps; fixed various bugs.

New in 0.991: fixed a serious allocation bug in 2D algorithm, which
caused random crashes. All users should upgrade to 0.991.

New in 0.990: bug fix in non-recombined 3D transfinite meshes.

New in 0.989: added ability to reload previously saved meshes; some
new command line options; reorganization of the scale menu; GIF
output.

New in 0.987: fixed bug with smoothing (leading to the possible
generation of erroneous 3d meshes); corrected bug for mixed 3D meshes;
moved the 'toggle view link' option to Opt->Postprocessing_Options.

New in 0.986: fixed overlay problems; SGI version should now also run
on 32 bits machines; fixed small 3d mesh bug.

New in 0.985: corrected colormap bug on HP, SUN, SGI and IBM versions;
corrected small initialization bug in postscript output.

New in 0.984: corrected bug in display lists; added some options in
Opt->General.

New in 0.983: corrected some seg faults in interactive mode; corrected
bug in rotations; changed default window sizes for better match with
1024x768 screens (default X resources can be changed: see ex03.geo).

New in 0.982: lighting for mesh and post-processing; corrected 2nd
order mesh on non plane surfaces; added example 13.
