Description

The documentation page http://eigen.tuxfamily.org/dox/TopicPreprocessorDirectives.html should document the two macros EIGEN_MAX_STATIC_ALIGN_BYTES, EIGEN_MAX_ALIGN_BYTES. I hear these let the user set an upper limit for the alignment of certain data (fixed-size matrix objects and heap-allocated dynamic sized matrixes).
