6347b1db5b remove sentence "Eigen itself is part of the KDE project."
it never made very precise sense. but now does it still make any?

312994fa98 opengl demo: add aligned operator new where appropriate and remove my
mess...

e6f1104b57 * fix Quaternion::setFromTwoVectors (thanks to "benv" from the forum)
* extend PartialRedux::cross() to any matrix sizes with automatic
  vectorization when possible
* unit tests: add "geo_" prefix to all unit tests related to the
  geometry module and start splitting the big "geometry.cpp" tests to
  multiple smaller ones (also include new tests)

247f2b0ffa * block() for vectors ---> segment()
* documentation improvements, especially in quickstart guide

e5c50afed6 * Quaternion: added dot product and angularDistance functions. The latter is
based on the former.
* opengl_demo: makes IcoSphere better (vertices are instanciated only once) and
               removed the generation of a big geometry for the fancy spheres...

5e9ee8863e opengl demo, now working:
- quaternion vs euler angles interpolation (though the Euler angle version looks a bit too bad)
 - navigation using either a mapping from 2D screen coordinates to 3D points on a sphere
   or the standard approach mapping mouse displacements as rotations around camera's axes.

146c9e4494 various stuff in opengl demos such as a better model,
stable trackball for the fly navigation mode, and started
to put some GUI elements...

f52d119b9c Solve a big issue with data alignment and dynamic allocation:
* add a WithAlignedOperatorNew class with overloaded operator new
* make Matrix (and Quaternion, Transform, Hyperplane, etc.) use it
  if needed such that "*(new Vector4) = xpr" does not failed anymore.
* Please: make sure your classes having fixed size Eigen's vector
  or matrice attributes inherit WithAlignedOperatorNew
* add a ei_new_allocator STL memory allocator to use with STL containers.
  This allocator really calls operator new on your types (unlike GCC's
  new_allocator). Example:
  std::vector<Vector4f> data(10);
  will segfault if the vectorization is enabled, instead use:
  std::vector<Vector4f,ei_new_allocator<Vector4f> > data(10);
NOTE: you only have to worry if you deal with fixed-size matrix types
with "sizeof(matrix_type)%16==0"...

a6d387a359 Various compilation fixes for MSVC 9. All tests compile but some
still fail at runtime in ei_aligned_free() (even without vectorization).

6f09d3a67d - many updates after Cwise change
- fix compilation in product.cpp with std::complex
- fix bug in MatrixBase::operator!=

f5791eeb70 the big Array/Cwise rework as discussed on the mailing list. The new API
can be seen in Eigen/src/Core/Cwise.h.

95549007b3 * fix error in divergence test, now it is even faster
* add comments in render() in case anyone ever reads that :P

56d03f181e * multi-threaded rendering
* increased number of iterations, with more iterations done before
testing divergence. results in x2 speedup from vectorization.

cacf986a7f - use double precision to store the position / zoom / other stuff
- some temporary fix to get a +50% improvement from vectorization until
  we have vectorisation for comparisons and redux

97a1038653 improve greatly mandelbrot demo:
- much better coloring
- determine max number of iterations and choice between float and double
  at runtime based on zoom level
- do draft renderings with increasing resolution before final rendering
