85fdcdf055 Fixed Geometry module failures.
Removed default parameter from Transform.
Removed the TransformXX typedefs.
Removed references to TransformXX from unit tests and docs.
Assigning Transforms to a sub-group is now forbidden at compile time.
Products should now properly support the Isometry flag.
Fixed alignment checks in MapBase.

92480ffd26 * Introduce make targets btest (build tests), blas (build blas lib), demos (build demos).
* remove EIGEN_BUILD_TESTS and siblings
* add summary at the end of cmake run, hopefully not too verbose
* fix build of quaternion demo
* kill remnants of old binary library option

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)

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).

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

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
