- changed "View.ArrowLocation" into "View.GlyphLocation" (this way we can
  also use this option to display the numeric values at the nodes,
  instead of displaying always at the barycenter)

- changed the numeric display of vectors (display the 3 omponents
  instead of the norm)

add line stippling for 2d plots

removed unused Post.Scales option

better subdivision scheme for drawing scalar hexahedra (with edges matching
on opposite faces)

axes color

new option to control a view's axes color

add missing line width spec

fix small bug in center-align for TeX output

- better test for drawing geo+mesh bbox
- ask if we want to uncompress gz files during merge

make center/right-align work for scales and 2d-plots, too

added a 5th axes mode: "Ruler" to help measure distances between any two
points

polish the last commit some more (activate/deactivate widgets, etc.)

a little more work on the axes stuff: enable global axes for the geometry and
the mesh, too. We can finally get rid of the ugly old "moving axes" bit.

(+ reverted changes in unproject: need to be more careful since unproject
can be called outside Draw())

- added an option to force the size/position of the 3D grids/axes

- cleaned-up the whole size/position thing of 2D/3D grids: it's much
  more consistent now (and the GUI is nicer)

- rewrote the algorithm for automatic positionning of 2D graphs (now
  they rescale with the window, which is much nicer--and far more
  practical)

- cleaned up (somewhat) + finished the euler angles/quaternion handling

- added a new little dialog in gui to specify the rotations/scales/translations by
  hand. This is similar to what I did in the Motif version of Gmsh a looooong time
  ago, and I was really missing this capability... (e.g. being able to specify
  exact rotation angles)

- the grid options now also apply to 3D views (this way we can
  finally get accurate size info for any data set; and the info
  is updated in real-time for gemeotry transformations & displacement
  maps)

- new option to specify the size of the moving axes

- generalized text align code (we now support the 9 modes that TeX
  does)

enhanced clipping planes (thick lines + easy "invert orientation")

added arrows to show the orientation of the cut plane

removed all unnecessary glPushMatrix/glPopMatrix calls

Merged patch from Matt Gundry <mjgundry@faa-engineers.com> to support
the structured Plot3d mesh format.

- New "Discrete Line" commands (similar to the Discrete Surface commands, but for
  curves).

  This permits e.g. to use Gmsh's extrusion mesh generators on 2D meshes (with
  boundaries) imported from other programs, and have all the useful elements
  generated (both volume and surface).

- Don't use Ctrl+m for File->Merge, as it is a reserved keyword for
  Window->Minimize on OS X:
  * File->Merge is now Shift+Ctrl+o (since it's in some way a variation of
    File->Open's Ctrl+o)
  * Tools->Options is now Shift+Ctrl+n

don' draw full stem in filled mode

fix normal orientation of second triangle

make simple arrows/pyramids look nicer when lighting is on

better estim of label width

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

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

small cleanup (+ remove solver link on webpage)

- renamed "Duplicate View" into "Alias View" (suggested by Philippe;
  less confusing since "Duplicate" implies that we actually copy the
  data, which is not what we are doing)

- added general "on the fly" tranformation matrix option. This allows
  for very efficient visualization of aliased datasets with
  non-destructive rotations, symmetries, etc.

remove unused glColor call

fix proto

- generalized Plugin(CutGrid):
   * now works also for lines/points (i.e., when nPointsU and/or nPointV == 1)
   * new option ConnectPoints

- new Plugin(Eigenvalues)

- don't force color in Draw_PlaneInBoundingBox

- removed all the crappy STL code and rewrote it using JF's POLY_rep
  class

- generalized POLY_rep so that we can use the polygonal discretization
  as a surface mesh, and mesh in 3D afterwards. I.e., we can now take
  an input triangulation (a single surface in STL format, multiple
  surfaces in STL format, one or more surfaces defined using the new
  "Discrete Surface" commands), and generate a 3D mesh that uses it. We
  could in theory even mix triangulated and "normal" surfaces in the
  same geometry, but nothing is done at the moment to ensure that the
  mesh at the interfaces would match (if it does, it actually works
  very nicely)

- new STL mesh output format to export a surface mesh as a STL file

- added an option to the GEO output routine to save the surface mesh
  as discrete surfaces associated with the geometrical surfaces

- added STL and Text output formats for post-processing views (the
  text output allows for example to exploit plugin-generated data in
  gnuplot)

- generalized Plugin(Evaluate):

  * can loop automatically over all the timestep and/or components

  * can do operations using data from an external view

     - if the 2 views are based on the same grid, the plugin does the
       evaluation very efficiently

     - if the 2 views are based on differenet grids, the plugin
       automatically interpolates the external view data onto the
       grid of the current view

- added new Rand() function in MathEval

- default colormap is now # 2 (the Matlab "Jet" colormap)

add option to specify the size of the small axes

copyright update

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

- better computation of translation coef in Draw2D

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.
