final tweaks

more tweaking

add "-cvs" extra tag for non-released versions

introduced GMSH_EXTRA_VERSION so that we can differentiate official/unofficial
releases

lena->lenna

arrow stuff is fixed

make parser && make depend

Fixed 3D cylinder/arrow drawing code when dir vector is // to z-axis

adding matlab msh reader from JF

wording

acos->myacos

Abort parser after 20 lines with errors (instead of trying to parse
everything, even huge binary files :-)

removed unused vars

Use sensible defaults for all *_choice widgets

- start file choosers in home directory if $PWD is not defined
- try to get $HOME on Windows too (not sure why I #ifdef'ed this)

Use bigger subdivision threshold for fake ps smooth shading

...and use vector ps/eps/pdf by default

disabled PostScript Level 3 shading operator by default (and added a
new option to change it: Print.EpsPS3Shading)

fixed typo

removed obsolete (and wrong) description of the physical entity
numbering requirements.

Fixed extrusion+rotation of points when axis direction is not
normalized

- Simplified the bounding box computation. It is now computed as
follows (after each include/merge/open):

1. If there is a geometry (i.e., at least one geometrical point), the
bounding box is taken as the box enclosing all the geometrical points;

2. If there is no geometry but there is a mesh (i.e., at least one
mesh vertex), the bounding box is taken as the box enclosing all the
mesh vertices;

3. If there is no geometry and no mesh, but there are some
post-processing views, the bounding box is taken as the box enclosing
all the primitives of the last post-processing view.

This should fix the weird things that sometimes happen when we animate
scenes that do not contain any geometrical entities.

- Deprecated MergeWithBoundingBox()

- Removed Replot()

- Removed the "Last_NumberOfPoints" hack in the parser

- Removed CTX.expose

fix gcc warning
