draw the clipping/cut plane dynamically when we change the coefficients

added an option to cut only volume elements

draw intersection of cutting planes with the bounding box

- added an option to draw the bounding boxes

- simplified the color_scheme options

- added tooltips to make the discovery of shortcuts easier

- added Orientation() members for hexas, prisms and pyramids

- use det3x3() instead of ad-hoc code everywhere it makes sense

little hack to visualize overlapping multi-patch spheres with constant
offsets (use timeStep<0...)

add "post-processor" keyword

add "reset" button in clipping window

clip plane doc update

simple clip example

generalized + added GUI for clipping planes

make depend

mesh smooth normals

remove debug message

- moved the smooth normals stuff into a separate file
- added smooth normal support for surface meshes (very nice!)

removed the bool hacks

note to self

bgm fix

add an area constraint on the elements in the initial mesh to make
the refinement nicer

- Triangle now supports our background meshes

- fixed memory leak in Optimize_Netgen (forgot to free the volume
  vertices) + added missing 2nd order reset

- fixed a couple of typos in the docs

only use POLYGON_OFFSET_FILL when it's really necessary (when we draw
edges)

put missing GPL license block

fix copy/paste (we need to skip 2 more chars if the string is colored)

set a parameter for the max number of elements per bucket
(default=100, which seems to be a good memory vs. speed trade-off for
meshes up to 1/2 million elements)

- allow more than 2 elements per bucket for ST!
- add missing tensor simplex case

1.54.1

- fixed seg fault in Plugin(Triangulate)
- added BBox computation in plugins when the coordinates are changed

added paragraph about the cygwin memory limit

doc Delete Volume

Never, O Never define WIN32 when compiling netgen!

cleanup the rpm build/source directory after the build

finally correctly implemented smooth normals for discrete isos (and
custom range). really nice :-)

enhance smooth normals with discrete isos (not perfect, but better)

make tag in distrib-pre

start from the current source tree (possibly pre-compiled) to build the
rpm

force a buffer flush when we abort the parser due to too many errors

don't force a full clean for distrib-* rules: if we want a "make clean",
let's do it by hand

fix crash when saving options and all views have been removed
