- fixed MED node ordering
- polished 64 bit Cocoa Mac OS X FLTK version
- updated copyright

extrema are not (yet) implemented => use 'custom' instead, ellipses are
coming ...

new sampling options to diplay one out of N elements (post-pro) or labels (mesh; this replaces the old labelsFrequency opt)

(useful for large datasets with number of components != 1, 3 or 6,
for which doing Plugin(Extract) would be too expensive)

re-committing work from last two days after server crash:

- refactored old Geo code (new/delete)
- moved DrawPlugin to Plugin
- move from matheval to mathex
- move from Flu_Tree_Browser to Fl_Tree
- fixed crash in Triangulate plugin

moved all string options to std::string

added File->Clear + changed behaviour of File->New (now just adds a
new model)

allow smaller fonts for palettes (test with "-deltafontsize")

use display list for 3d arrows (approx. 2x speedup on my laptop for
large vector views) and spheres

removed static quadrics (wrong when \exists multiple gl contexts),
replaced with correct(?) init in drawContext

- fix bb computation to avoid model jumping around when adding points in z=0 plane
- pass interpol matrices as ref

view limit

untabify

added new "Normal raise"

added adaptive view options in the view's option db

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 ***

store vectors in "pseudo" vertex arrays to avoid looping over elements
in the drawing loop
