Also, under options->mesh, there is an important difference between surface/volume mesh visibilities.

1) all the mesh formats supported by Gmsh are "3D"
2) the p3d format is actually *not* supported anymore (use Gmsh 2.0!)
3) there's a little script in the source distribution (in the
utils/converters/matlab directory) that reads .msh (version 1) files
directly into Matlab.

> I am trying to create a 3D mesh of a sphere. it looks good in GMSH but when I save it in MSH format, it just saves the surface of the mesh and the p3d format (which seems to be the only 3D format GMSH supports) is not working.
