add option to specify the size of the small axes

use v0, v1, ..., vn to access the other components of the field

add special token "Today" to return the current date

"make purge" should also remove .#* files

fix small mistake in definition of char-expression

copyright update

- More intelligent way to detect if we need to apply a polygon offset
or not.

- better computation of translation coef in Draw2D

remove extra test on !port

better handling of end-of-string characters in text strings (which removes
the need for the ugly '^' hack) -> bumped file format version from 1.2 to 1.3

The TCP patch broke UNIX solckets on Winwows (since Windows paths can
contain a colon)

the TCP patch broke UNIX sockets on Windows (since Windows paths already
contain a colon)

sanitize TeX strings in an "intelligent" way

Added 2 options to control polygon offset. Instead of trying to guess
when a polygon offset is useful (it's no that simple when we combine
geo+mesh+some views), we just apply it conditionally to all surface
drawings.

optimize ExportLc

test if there is anything to save before opening the file

generalized ExportLcField to all element types

fixed computation of Min/Max when the view contains different element types

pretty print messages and comments

Ctrl+a->Shift+a

Replaced all *non-modal* Fl_Windows with either Dialog_Windows or
Main_Windows, which are derived from Fl_Window amd correctly process
the OS-specific "Close Window" shortcuts (Pomme+W on MacOS, Alt+F4 on
Win32).

Opengl_Window should not take the keyboard focus by force as soon the
mouse enters its area (this messes up the processing of other windows
shortcuts). Instead, it should only force the focus when it gets a
mouse click. This is much nicer.

prevent crash when no contour

Small aesthetic changes:

- Only 'title-capitalize' window titles and menus; the rest should be
  capitalized like normal english sentences

- The window title should be exactly the same as the menu item
  (without the ellipsis character if there is one)

Print "Shift+Ctrl" instead of "Ctrl+Shift" in the docs, since this is the
way both FLTK and MacOS do it

show 'About' window in the middle of the screen

final shortcut changes decided by Laurent

- On Mac, Cmd==Ctrl
- better menu dividers

- reworked the keyboard shortcuts with Laurent (our very own Macintosh
  Usability Guidelines Expert)

- new smoothing option for jpeg output

- new small GUI dialogs for ps/pdf/jpeg/gif/msh output (makes the
  'format' menu in the file dialog much shorter)

bulletproof parse_string and skip_until so that we don't crash and simply
report the error + use Msg instead of YY_FATAL_ERROR in YY_INPUT

Fixed all (well, most) string memory leaks in the parser. I've run
automated tests on all the demos and benchmarks, and I did not see
anything suspicious (no crashes, double frees, etc.)

For/EndFor loop corrections  exposed small bug here :-)

Don't optimize Gmsh.tab.o: on many architectures, g++ -O2 generates
assembly code too large to be addressed correctly. This will hopefully
fix the build problems reported on ppc.

don't need UpdateViewsInGUI in parser anymore
