1f5024332e First part of a big refactoring of alignment control to enable the handling of arbitrarily aligned buffers. It includes:
- AlignedBit flag is deprecated. Alignment is now specified by the evaluator through the 'Alignment' enum, e.g., evaluator<Xpr>::Alignment. Its value is in Bytes.
 - Add several enums to specify alignment: Aligned8, Aligned16, Aligned32, Aligned64, Aligned128. AlignedMax corresponds to EIGEN_MAX_ALIGN_BYTES. Such enums are used to define the above Alignment value, and as the 'Options' template parameter of Map<> and Ref<>.
 - The Aligned enum is now deprecated. It is now an alias for Aligned16.
 - Currently, traits<Matrix<>>, traits<Array<>>, traits<Ref<>>, traits<Map<>>, and traits<Block<>> also expose the Alignment enum.

d5f3b2dc94 change the Arch constants: const int ---> enum, more explicit names, and use
of a namespace instead of Prefix_Name.

6219f9acfa * rename new Quat class to Quaternion, remove existing Quaternion
* add Copyright line for Mathieu
* cast() was broken (compile errors) and needed anyway to be in QuaternionBase
* it's VectorBlock<T,3>, don't pass additional parameter 1, it has different meaning!!
* make it compile with GCC (put 'typename' at the right location)

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