make depend

OCCFace::containsPoint() did not correctly take orientation of edge loop
into account (fixes bug reported by Jacques Kools about cross in OCC plane
faces not drawn)

make clear in docs that node/elemement tags should be > 0 (and not == 0)

removed global THEM

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

add experimental support for automatic on-the-fly boundary computation
in vertex arrays

manage GModel::list automatically (like PView::list)

fix BDF small field export on Windows (apparently Windows does not conform
to ANSI C and uses 3 digits in %e instead of 2)

better normals

- print extra info for faces and volumes
- added couple of examples

- don't use vertex arrays for quads anymore (they are wrong for non-plane
quad faces): just use triangles everywhere

- removed _links in PView

- various small cleanups

tweak 2d graph + other small fixes

all that was there is back (can be enhanced later)

start reintro high order rep

rewrote vertex array code for meshes in the same way we do it now for
post-processing (much simpler, pretty much same speed, and takes a bit
less memory)

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 ***

airplane work: more work to complete remaing features (read, combineSpace,
combineTime) in new post-pro

added simple boundary operator in parser

lots of improvements to boundary layer generation: we can now constuct
and mesh models with entities connected to boundary layer points, edges
and faces

fix position of BoundaryLayerPoints

- re-add smooth() for PViewDataList

fix bug for ruled surfaces with holes (part 1)

CatMullRom->Spline

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