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

910b387438 Add sub/super-diagonal expression (read/write) as a trivial extension of 
DiagonalCoeffs. The current API is simply:
  m.diagonal<1>() => 1st super diagonal
  m.diagonal<-2>() => the 2nd sub diagonal
I'll add a code snippet once we agree on this API.

93a089adc8 disable alignment altogether outside of the platforms which potentially have SSE or AltiVec 
This should remove most portability issues to other platforms where data alignment issues (including
overloading operator new and new[]) can be tricky, and where data alignment is not needed in the first place.

36c8a64923 add MatrixBase::stableNorm() avoiding over/under-flow 
using it in QR reduced the error of Keir test from 1e-12 to 1e-24 but
that's much more expensive !

9bc44094c5 add EIGEN_NO_AUTOMATIC_RESIZING 
if defined, already initialized matrices won't be automatically resized in assignments
uninitialized matrices may still be initialized

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.

f6aa60bcf3 centralize those static asserts more upstream, reduces duplication and ensures they can't be bypassed (e.g. 
until now it was possible to bypass the static assert on sizes)

00d7f8e567 * solveTriangularInPlace(): take a const ref and const_cast it, to allow passing temporary xprs. 
* improvements, simplifications in LU::solve()
* remove remnant of old norm2()

9849931500 eventually it turns out that our current 
EIGEN_WORK_AROUND_QT_BUG_CALLING_WRONG_OPERATOR_NEW_FIXED_IN_QT_4_5
is the right way to go for allowing placement new on a class having
overloaded operator new. Qt 4.5 won't add the :: prefix. (I still do not
understand how you can distinghish a placement new from an overloaded
operator new taking an allocator as argument...)

5f43a42ee7 * remove set(), revert to old behavior where = resizes 
* try to be clever in matrix ctors and operator=: be lazy when we can, always allow
  to copy rowvector into columnvector, check the template parameters,
  try to factor the code better
* add missing copy ctor in UnalignedType
* fix bug in the traits of DiagonalProduct
* renaming: EIGEN_TUNE_FOR_CPU_CACHE_SIZE
* update the dox a little
