- new "Delete Empty Views" command
- new View.MinX, View.MinY, View.MinZ, View.MaxX, View.MaxY, View.MaxZ options
- added example on how to do simple volume visualization

add color options for elements in views (requested by Philippe a long
time ago)

power law for the alpha channel

typo

add all remaining colormap parameters as options

added File->Rename menu

one can now specify a TIME list of values in parsed views to give the
values of the time (or whatever) steps (like in ascii/binary views)

typo

renamed Plugin(PrincipalStresses) into Plugin(Eigenvectors) + provide the
option to disable the scaling by the associated eigenvalues

typo

new plugin to compute the principal values of a tensor field

- Moved all the Raise[][] stuff out of the drawing routines, and into
  Graphics/Post.cpp

- New 'generalized raise' mode (can use arbitrary expressions, possibly
  with external data sources, to raise/offset views dynamically). Original
  patch by Nicolas Tardieu. Merci Nico!

The "Simplex" class is now derived from a new class "SimplexBase",
which contains only pointers to the nodes, and none of the other stuff
necessary for the actual mesh generation.

All the input/output/display routines have been rewritten in terms of
SimplexBase: this provides a gain of almost 50% in memory when you
just load meshes from .msh files to do visualization stuff, instead of
actually generating the mesh.

doc update

- First draft (pretty much untested!) of new "Integrate" plugin to
  * integrate scalar fields over all the elements in a view
  * integrate the circulation of vector fields along line elements
  * integrate the flux of vector fields across surface elements

  Used with Plugin(DisplacementRaise) and Plugin(Evaluate) this
  permits for example to compute the area/volume of deformed
  configurations; and, with Plugin(CutPlane)+Plugin(Skin), the
  perimeter of deformed sections. Another interesting application is
  to use it on a vector field with Plugin(CutPlane), in order to
  compute fluxes across arbitrary cross-sections.

- Added "connectPoints" option to Plugin(CutParametric) so
  that we can feed its output to Plugin(Integrate)

- Added Normals and Tangents options to visualize the orientation of
  elements in post-processing views

- Added "swapOrientation" in Plugin(Transform) to change the
  orientation of the elements (in place) (+ moved the transformation
  routines from the view class into the plugin)

- fixed #defines in some of the plugin header files

fix broken english

HarmonicToTime

if we have no geometry and no mesh, use the max of all view bounding boxes
(instead of the bounding box of the last view only)

forgot to update help strings

add note on tensor field display

new solver options: SocketCommand and NameCommand (patch by
<C.Stott@surrey.ac.uk>)

fixed small syntax mistakes (missing semi-colons, etc.)

- added a couple of entries in the FAQ
- inluded the FAQ in the texinfo manual
- merged README.gui in the texinfo manual

1.56

reworked the "post-processing file format" section

slightly reworked interactive/non-interactove section

explain that "Duplicata View[i]" does not actually copy the data

add an option to draw the post-processing scales horizontally + remove
Post_View.TransparentScales (never really worked well anyway)

renamed mshdensify to mshsort and modified the spec file to install it
in the rpm

update BoundingBox doc to match what the code actually does + explain
relative/ansolute paths + small 'cosmetic' changes
