3009d79a1f * allow Matrix to be resized to 0 (solve a lot of troubles with
some containers)
* new workaround for std::vector which is supposed to work for any
  classes having EIGEN_MAKE_ALIGNED_OPERATOR_NEW as discussed on ML

1b194193ef Big change in DiagonalMatrix and Geometry/Scaling:
* previous DiagonalMatrix expression is now DiagonalMatrixWrapper
* DiagonalMatrix class is now for storage
* add the DiagonalMatrixBase class to factorize code of the
  two previous classes
* remove Scaling class (it is now a global function)
* add UniformScaling helper class
  (don't use it directly, use the Scaling function)
* add the Scaling global function to simplify the creation
  of scaling objects
There is still a lot to do, in particular about DiagonalProduct for which
the goal is to get rid of the "if()" in the coeff() function. At least
it is not worse than before ! Also need to uptade the tutorial and add more doc.

eb7dcbbfce EIGEN_MAKE_ALIGNED_OPERATOR_NEW didn't actually need to get the class
name as parameter

1d52bd4cad the big memory changes. the most important changes are:
ei_aligned_malloc now really behaves like a malloc
 (untyped, doesn't call ctor)
ei_aligned_new is the typed variant calling ctor
EIGEN_MAKE_ALIGNED_OPERATOR_NEW now takes the class name as parameter

1c29d70312 * introduce macros to replace inheritance for operator new overloading
(former solution still available and tested)
  This plays much better with classes that already have base classes --
  don't force the user to mess with multiple inheritance, which gave
  much trouble with MSVC.
* Expand the unaligned assert dox page
* Minor fixes in the lazy evaluation dox page

9c8a653c0b gaaaaaaaaaaaaaaaaaah
can't believe that 3 people wasted so much time because of a missing &
!!!!!
and this time MSVC didn't catch it so it was really copying the vector
on the stack at an unaligned location!

fabaa6915b * fix in IO.h, a useless copy was made because of assignment from
Derived to MatrixBase.
* the optimization of eval() for Matrix now consists in a partial
  specialization of ei_eval, which returns a reference type for Matrix.
  No overriding of eval() in Matrix anymore. Consequence: careful,
  ei_eval is no longer guaranteed to give a plain matrix type!
  For that, use ei_plain_matrix_type, or the PlainMatrixType typedef.
* so lots of changes to adapt to that everywhere. Hope this doesn't
  break (too much) MSVC compilation.
* add code examples for the new image() stuff.
* lower a bit the precision for floats in the unit tests as
  we were already doing some workarounds in inverse.cpp and we got some
  failed tests.

09fd69d734 * add Transform explicit constructors taking translation/scaling/rotation
* add Transform::operator= taking rotation.
  An old remnant was left commented out. Why was it disabled?
* slight optimization in operator= taking translation
* slight optimization (perhaps) in the new memory assertion

c1e2156d8a * Much better, consistent error msgs when mixing different scalar types:
- in matrix-matrix product, static assert on the two scalar types to be the same.
- Similarly in CwiseBinaryOp. POTENTIALLY CONTROVERSIAL: we don't allow anymore binary
  ops to take two different scalar types. The functors that we defined take two args
  of the same type anyway; also we still allow the return type to be different.
  Again the reason is that different scalar types are incompatible with vectorization.
  Better have the user realize explicitly what mixing different numeric types costs him
  in terms of performance.
  See comment in CwiseBinaryOp constructor.
- This allowed to fix a little mistake in test/regression.cpp, mixing float and double
- Remove redundant semicolon (;) after static asserts

94f6f2a7de Add an axis aligned box in the geometry module.
Some naming questions:
- for "extend" we could also think of: "expand", "union", "add"
- same for "clamp": "crop", "intersect"
- same for "contains": "isInside", "intersect"
=> ah "intersect" is conflicting, so that eliminates this one !

e5b8a59cfa Add smart cast functions and ctor with scalar conversion (explicit)
to all classes of the Geometry module. By smart I mean that if current
type == new type, then it returns a const reference to *this => zero overhead

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...

  bug found today in SVD won't happen again.

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"...
