change sign of levelset so that the iso-volume is more natural

added interactive callbacks in CutParametric and Annotate

removed all unnecessary glPushMatrix/glPopMatrix calls

typo

add element size computation

Plugin(Extract) can now also extract data from a specific time step

Generalized Plugin(Extract) so that it can also create tensor views

small generalization: we can now interpolate data from abritrary
views (and not only from views having the same data type as the
destination)

I use this to interpolate (combination of) components of a field
in one mesh onto another mesh, for example a set of isosurfaces
from another field. Wicked cool! ;-)

couple of test files

small doc fixes

- generalized the octree code to make it work with all the element
types, and not only with triangles/tets (and fixed a couple of copy &
paste bugs in the process...)

- modified all depending plugins to take advantage of this

change the behavior of "-string string" command line option to match the
bahavior of "-option file"

extrusion of discrete curves/surface with mesh that does not fit the geometry

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

avoid crashes if trying to transform a curve with no begin/end points

smaller init alloc in curves

Use the curve's end points id numbers for the end vertices (as we do
in the normal 1D algo). This is what the old extrusion algorithm
expects.

fixes for discrete curves/surfaces

copy/paste bug

modified Read_Mesh and Print_Geo so that we can save line/surface meshes
loaded from a file as discrete geometries

- 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

update less often for small meshes

Added progress message while reading .msh files (idea from Nicolas)

Instead of popping up a progress bar, I just used a Msg() call. Not
sure which is best, but this is a bit simpler..

make maximize reversible

add "Window" menu on Mac OS X

fix gcc warning

fixed crash when trying to extrude a discrete surface + minor mods in the faq

mention python
