remove unused test

don't force CC on sgi anymore

extra \

sgi fixes

sgi compile fix

simpler options for sgi

use same rules as for our own parser to  avoid any implicit rules on
.l and .y files (fixes compile pb on irix with sgi's old 'make')

update gl2ps

force ./unix2dos (if . is not in the path)

reset the list of trsf pnts if we redefine a transfinite entity multiple
times by mistake

played around with colors

use the partition number and not the parition index to choose the partition
color

increased size of mesh color carousel from 10 to 20

redundant

obsolete

remove the VerticesTemp hack, as it was not the main bottleneck

example to show how to extrude an external surface mesh

Removed the last bits of the "Discrete Surface/Line" stuff.

Gmsh can now simply read a .msh file, and use it as the boundary mesh
of a 3D mesh. For an example on how to do this, cf.
demos/sphere-discrete.geo.

This complements nicely the STL remeshing stuff: Gmsh can now
for example very easily be used to extrude surface meshes that
come from other tools.

fix old extrude of existing meshes

make full-quad algo work for non-plane surfaces

reorder

cosmetic

fixed full-quadrangle recombine algo:

- run globally, not for each surface
- assign entities to elements
- split line meshes
- correctly re-tag vertices as 1st order
- plug memory leaks

cosmetic

add little menu to choose the quality measure in Options->Mesh->Visibility
