make sure we define  YY_NO_UNISTD_H on wind32

make parser embeddable in code with other parser (yy->gmsh_yy)
more work on headers
fixed lots of gcc warnings

start reducing header pollution (removed Gmsh.h + cleaned up GModel & co)

rename transf params & remove unused ones in old structs

fix parser to work with new flex and bison (1.28 -> 2.3)

added adaptive view options in the view's option db

removed global THEM

(once more step towards nicer integration of old GEO stuff)

reinterfaced adaptive views with new post-pro

moving to new post-processing database

                    *** WARNING ***

do not upgrade if you need plugins or adaptive views: these have not
been ported (yet) to the new database

                    *** WARNING ***

allow Function Field(1)="expression"; (without extra empty list at the end)

added simple boundary operator in parser

add bit of code to intersect curves with a surface (allows to do "poor man's"
trimmed patches ;-)

- removed static GMODEL (can now have multiple models)
- added infrastructure for new post-processor module

Bezier curves are broken

small cleanups for 2.0.8

warning->error when trying to assign explicit reg ids in extrusions
+ add note in doc for this

tCircle and tCoherence were removed from the lexer? WTF?

background mesh. I've still to write some fields sub-class, but backward
compatibility should be ok now.

----------------------------------------------------------------------

prepare for named string expr

- preliminary work to interface more parser functions with general
  GEntities

- we can now export simple GModels as.geo files (points, straight line
  segments, plane surfaces, ruled surfaces and volumes are treated
  correctly; all non-straight-line curves are exported as splines; all
  non-plane/ruled surfaces are not exported)

- tentative fix for the unv export problem reported on the mailing
  list (fprintf() buggy on some machines??)

- new IO (both read and write) for structured grids using the NASA
  Plot3D format (for Olivier)

fix syntax for hole carving

- boundary layer can now be generated by using a post-pro view for the
  normal field

- added more operations on lists in parser (FExpr * FExpr_Multi, etc.)

- new "hole carving" code to create extruded grids carved out around
  some surfaces (the resulting cavity can be filled with "grout" using
  the unstructured algos)

- check if bboxes of post-pro views are not == VAL_INF before adding
  them to the model bbox (bug report from Renaud Sizaire)

- fixed crash in LCM_xxx tensor drawing code when no tensor points are
  available. (This piece of code should be cleaned up further--no time
  for that now.)

- generalize Levelset plugins so that they work on point data sets

new boundary layer mesh generator

refactored smooth value/smooth normal code into single SmoothData.* file

added General.MinX, General.MaxX, etc. so that we can easily get the
min/max of a model (useful e.g. to create a box around an imported
STEP model)

added example of mixed step/geo model

include the geometrical entities defined in this script (since we
import THEM into GModel *after* we've parsed the file)

orientation bug in extrusion
