- converted 2D_Recombine and SecondOrder to the EdgesContainer class
- removed the quadrangle hak and the ugly EdgesInVolume global from 3D_Coherence

nicer layout of mesh color pane

copy & paste buglet

- Fixed second order mesh generation in 3D (on simplices only at the moment).

- In prevision of the extension to hexas, prisms and pyramids, all elements
are now derived from a new Element base class, which will be used in the
generalization of Edge/EdgesContainer in the future.

Improved xytouv() and xyztouv() by trying different initial guesses in the
newton algo (before relaxing). Should be more robust than what we did before.

added new constructor with no arguments in prevision of Degre2 cleanup

Fixed computation of vertex->u param in curve extrusion

- Fixed drawing of 2nd order triangles and tets
- Restored drawing of 2nd odrer vertices in different color

cleanuip (removed duplicate code) + new function u() to get the abscissa
more easily

better progname

another example where the simple projection scheme fails

add comments

final tweaks

more tweaking

add "-cvs" extra tag for non-released versions

introduced GMSH_EXTRA_VERSION so that we can differentiate official/unofficial
releases

lena->lenna

arrow stuff is fixed

make parser && make depend

Fixed 3D cylinder/arrow drawing code when dir vector is // to z-axis

adding matlab msh reader from JF

wording

acos->myacos

Abort parser after 20 lines with errors (instead of trying to parse
everything, even huge binary files :-)

removed unused vars

Use sensible defaults for all *_choice widgets

- start file choosers in home directory if $PWD is not defined
- try to get $HOME on Windows too (not sure why I #ifdef'ed this)

Use bigger subdivision threshold for fake ps smooth shading
