free vol mesh befire surf mesh

ProcessSelectionBuffer should only return true if there is actually
something returned

better integration with mac finder

remove "file_type" for open callbacks: it gives the wrong impression
that files will be treated differently depending on the choice (as is
the case for save callbacks)--this is not true

pretty print

destroy meshRep in deMeshGEdge

OpenProblem -> OpenProject
MergeProblem -> MergeFile

cleanup msg

change the logic in GenerateMesh():

- never reload the model file--we don't need this trick anymore!

- always only generate the mesh we are asked to generate (pressing
  "1D" should *always* mesh the edges; pressing "2D" should only mesh
  the surfaces, unless there is no 1D mesh). This makes the behavour
  much more predictable when changing mesh attributes interactively.

small cleanup of session/option file (don't print help strings by defaul)

add one level of undo in interactive visibility hiding

fix interactive modification of mesh attributes

sanity check: don't try to tetrahedralize a volume with quads on the boundary

clenup projectionFace a bit

don't force (annoying) vis_window->show() aftereach operation

better handling of "negative" physical groups

prepa invert_selection + remove some debug prints

2 fixed bugs and 2 new ones

gmsh 2.0 fixes all of these

fix warning

first gui hooks for projection stuff
+ fix potential crashes in drawMeshGxxx if mesh.changed was not set correctly

Add middle edge points to compute mean plane of plane faces with less
than 3 bounding points

better conv warning

switch license to standard gmsh license

cleanup

update for version 2

Layers{N,1} can now be written simply as Layers{N}

sugg by oscar: save->save as defaults

don't put the cut plane options in the disabled group (forces to compute
all even if only want to show cut)

algo2d=triangle is not available at the moment
