if element faces are drawn use vertex color instead of entity color (similar to what we do for element edges)

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

this on platforms without full opengl... on ipad? :-)

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

drawing vertices per element

locks in openglWindow.

- don't even try to process selection buffer if model is empty (partial fix for bug #1)

 ***** this is a potentially dangerous commit

- moved GUI to FlGui + added experimental QGui to test Qt

- fixed most MSVC and gcc compiler warnings

- converted some remaining tabs to whitespace (that's why the patch is
  so large; please try to remember to indent with 2 spaces and not
  tabs when you commit stuff to CVS)

- merged modified patch from Konstantinos Poulios to allow saving
  physical/partition as element tags in mesh formats that don't
  support them natively

- replaced old 2nd order views with new adaptive stuff (still missing
  some function spaces for quads/hexas)

drawing code from another widget toolkit)

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

window with experimental tree browser

There's no new functionality for now: PLEASE TEST THAT EVERYTHING
WORKS AS IT USED TO BEFORE.
