shorter intro

include metis in the free version since we now have Karypis' approval

tweak automatic polygon offset check

make "BoundingBox{x,X,y,Y,z,Z}" actually do what the documentation claims
it does

The current behavior of Gmsh when drawing 3D scalar fields is not coherent
with what is done in 2D: to draw filled iso-values or continuous maps in 3D,
we should ideally do volume rendering. Right now we draw the iso-values
(i.e., surfaces), which is both not coherent with the definition of
continuous maps or filled iso-values, but is also annoying when trying to
visualize fields that are constant per element (since in that case nothing is
displayed!)

Until we can do volume rendering, I've changed the behavior to draw the
solution on the boundary of the 3D elements. It's rather slow, but it's the
right thing to do visually.

print 1D elts in unv format + fix 2nd order 1d elts in unv format

indent + cleanup messages (somewhat)

fix gcc warnings + disable BDS optimization for now (it leads to wrong
results with gcc 4; maybe we should have more intelligent tests in
configure or in the makefiles to enable/disable optimization depending
on which compiler is used)

make it possible to add second order vertices for a mesh read from
a file (without cad)

disable the "manually add edges" for now

Don't reinitialize the symbol tree in OpenFile.

(We don't reinitialize the option database, so why should we reinitialize
the variables? Using a single global symbol tree we can again define
variables with -string "" on the command line.)

add fixme for extract volume in 2D (orientation of quads)

update email

currently we cannot bundle Metis with the sources

if the mesh is partitioned, save the partitions in the .msh file

add missing copyright headers

more compact STATUS labels

put STL operations in a new submenu
