Removed extra arg for Init_Mesh

Added support to visualize mesh partitions. The partition info is currently
set as the physical entity number in the MSH file, but it would be trivial
to change it to something else (e.g., as soon as we generalize the MSH
format to take arbitrary number of tags per element).

Some morer work on second order elements

Fix whitespace in copyright headers

Remove garbage

Add Layer on Extrude Point (phase 2 -- remove duplicates)

Fix crash due to identical vertex pointers in Mesh.Points and
Mesh.Vertices

Indented all source files using utils/gmshindent

Updated copyright

Introduce OpenGL display lists for drawing meshes. Does not seem to
work much faster on my machine, though.

New global volumic extrusion algorithm. New extrusion should now be the same (right or wrong!) as old extrusion...

NOT work: it creates duplicate points, etc.). Sorry!

better handling of opened files (msh+pos)
min/max computation for msh pos
