c29c7b0ea9 Fix bugs reported by Timothy Hunter:
* CholeskyWithoutSqrt with 1x1 matrices
 * .part<Diagonal>()
Updated unit tests to handle these cases

e14aa8c8aa Add coeff-wise comparisons to scalar operators. You can now write:
mat.cwise() < 2
instead of:
   mat.cwise() < MatrixType::Constant(mat.rows(), mat.cols(), 2)

59dc1da5bf Add a Select expression in the Array module which mimics a coeff-wise ?: operator.
Example:
  mat = (mat.cwise().abs().cwise() < Ones()).select(0,mat);
replaces all small values by 0. (the scalar version is "s = abs(s)<1 ? 0 : s")

3bbd1b3114 Bugfix regarding alignent in Assign.h (updated map unit test to detect this bug)
Anyway: LinearVectorization+CompleteUnrolling actually uses the InnerVectorization
unrollers, so these two cases could be merged to a single one...

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"...

46fe7a3d9e if EIGEN_NICE_RANDOM is defined, the random functions will return numbers with
few bits left of the comma and for floating-point types will never return zero.
This replaces the custom functions in test/main.h, so one does not anymore need
to think about that when writing tests.

c931867909 also use EIGEN_SOURCE_DIR here. according to grep this was the last place to
change.

ff60c9ccb1 fix cmakelists: wrong assumption on CMAKE_SOURCE_DIR. One can now use
EIGEN_SOURCE_DIR for that use, guaranteed to point to eigen2/ directory.

9c450a52a2 Split Rotation.h to Rotation2D.h and RotationBase.h,
and more code factorization based on RotationBase.
Added notes about the main aim of the Translation and Scaling classes.

6ba991aa3a * added a RotationBase class following the CRT pattern
This allow code factorization and generic template specialization
  of functions
* added any_rotation * {Translation,Scaling,Transform} products methods
* rewrite of the actually broken ToRoationMatrix helper class to
  a global ei_toRotationMatrix function.

f1e6c56b77 * rename TranformationKnowledge to TransformTraits
* apply the same principle to extractRotation and fix it to
  extract a rotation corresponding to a positive scaling

236b7a545d update Transform::inverse() to take an optional argument stating whether the transformation is:
NonAffine, Affine (default), contains NoShear, contains NoScaling
that allows significant speed improvements. If you like it, this concept could be applied to
Transform::extractRotation (or to a more advanced decomposition function) and to Hyperplane::transformed()
and maybe to some other places... e.g., I think a Transform::normalMatrix() function would not harm and
warn user that the transformation of normals is not that trivial (I saw this mistake much too often)

9e7a9cde14 Add Scaling and Translation class as discussed on ML, still missing:
* handling Quaternion, AngleAxis and Rotation2D, 2 options here:
 1- make all of them inheriting a common base class Rotation such that we can
    have a single version of operator* for all the rotation type (they all get converted to a matrix)
 2- write a version for all type (so 3 rotations types * 3 for Transform,Translation and Scaling)
* real documentation

063d1bb811 tweak root/Mainpage.dox to make it compatible with kde's doxygen.sh script
plus some hacks to compile the examples from doxygen...
Hopefully, api.kde.org/eigen2 will be beautiful by tomorrow....

6d841512c7 some hyperplane changes:
- the coefficients are stored in a single vector
- added transformation methods
- removed Line* typedef since in 2D this is really an hyperplane
  and not really a line...
- HyperPlane => Hyperplane
