- the main menu is now scrollable when there are more than 25
buttons and it can handle an arbitrary number of buttons (this removes
the "100 views max in the GUI" limitation)

- the view number is now also displayed in the menu (to make it easier
to find the view when one has many many views)

- added "Remove empty views" menu item

obsolete

wording

A function was bugging gcc 3.3.3

Changed the order in which we compute the bounding box of a scene: look
for mesh vertices first, then look for geometry points. I think this is better,
since more and more people use the code just to visualize meshes (without
geometries); as soon as there was one physical point in the mesh, the resulting
bb could seem strange (as the physical points create geometrical points).

missing case

fix cygwin bustage

compress the icons

new document icons on OSX (geo, msh, pos)

added min/max/step for displacement_factor

added W coordinate for light sources (so that we can have "spot sources")

small opti

For all our mechanical engineering friends out there, I just cleaned up the stuff
I did with Sean last year, i.e., allow to draw a vector field as a displacement
map, with another scalar field displayed instead of the displacement norm.

It's basically the same as Plugin(DisplacementRaise), but it does not modify the
actual data inside the view (so e.g. you cannot save it). Instead, it's implemented
as an alternative "Vector display" mode. This allows to easily animate deformed meshed
with arbitrary scalar fields drawn on them. (The GUI for this is kinda lame, but
it works: just select Vector display->Raised scalar view, select the scalar view
number, et voila.)

I also generalized the smooth normal code path a little, so that we can have smooth
normals for vector-as-displacement and tensor-as-von-mises plots, too.

fix spelling

- set glBlendEquation explicitly
- make parser

old comment

moved the footnotes at the end of the page

1.55

minor text mods

add missing #ifdef HAVE_FLTK

revert changes

make code compile on Mac again

better label for "constrain bg mesh"

fix support for multiple light sources (+ add a couple of options to set
the light color and specular reflection exponent)

typo

Don't call Mesh_Quality() in GetStatistics()

added vertex arrays in volumes to store the boundary of the cuts
when we draw them "as surfaces" (for Philou, not tested yet)

fixed small bug in ReplaceDuplicateCurves where we woudn't eliminate
identical CIRC/CIRC_INV ELLI/ELLI_INV pairs

re-add return statements in functions returning non-void. JF: my compiler
wants this (and he's right)

small copy/paste mistake in my last commit

make depend
