put call to value() after filter() so that we see the chosen file if we specify one

fix for the annoying "disappearing path" problem in the file chooser

simpler Start() function

removed extra white space and node coord format in UNV export

- added new "spectral" colormap (truncated hsv)
- added GUI button for elliptic mesh + geometry coherence
- added GMSH_MAJOR_VERSION, GMSH_MINOR_VERSION and GMSH_PATCH_VERSION
  in the parser

remove debug printf call

change orientations so that all the "discrete" sphere demos also work with netgen

add comments

don' draw full stem in filled mode

added check for socklen_t in configure script

fix normal orientation of second triangle

make simple arrows/pyramids look nicer when lighting is on

better estim of label width

allow negative line loop number in surface definitions

Adding python solver interface from Carl Osterwisch <osterwischc@asme.org>.

The interface comes with a example python "solver" that converts an Abacus
result file (in CSV format) into Gmsh post-processing views. Very cool ;-)
Thanks Carl!

Fl_Double_Window is not really necessary for Main_Window

Create windows as Fl_Double_Window (double-buffered) instead of
Fl_Window. This makes the GUI "smoother" on Windows and Linux. The Mac
port of FLTK actually always uses Fl_Double_Window, even when one asks
for an Fl_Window...

typo

capitalize tab headers

%g->%.3g + use format also for 2d graphs

set default number format to %g, and use it to display the time value, too

more intuitive behaviour of geometry+mesh selection

better Tools->Visibility GUI

typo

- fixed the "unix socket name is one character short" problem on
MacOS and AIX. Unfortunately, this required the client code to be
slightly modified as well (and as a consequence, old versions of getdp
will for example not work with new versions of Gmsh on MacOs and
AIX). But it's better to do things "the right way" (TM) for people who
want to connect using different languages (Perl, Python).

- moved the GmshServer stuff in its own class

- added missing rules in parser makefile (so that the parser gets
  rebuilt automatically when one changes Gmsh.y or Gmsh.l)

ask if we should remove the temp files

small cleanup (+ remove solver link on webpage)

new "AliasWithOptions" command

use C++ example in doc instead of C

tiny cleanup

build solver examples with ${FLAGS}, so that on Windows they receive the
-mwindows argument
