Summary: some operator* tweaking

Initial Comment:
there is a bunch of operator*
maybe they can be replaced with somethink like:

template <typename T, typename DATA_TYPE, unsigned
ROWS, unsigned COLS>
inline T operator*( const Matrix<DATA_TYPE, ROWS,
COLS>& matrix, const T& in)
{
   T temporary;
   return xform( temporary, matrix, in);
}

or even:

template <typename T, typename M>
inline T operator*( const M& matrix, const T& in )
{
   T temporary;
   return xform( temporary, matrix, in );
}

Message:
I think that this is worth pursuing, but it will not be as simple as what
you have proposed. The issue is that there are overloads of operator* where
a fundamental type is passed as an argument (such as scalar multiplication
of a vector). Perhaps the solution is to make gmtl::xform() more general
first so that all operator* uses end up getting handed off to an overload
of gmtl::xform(). That is the first thing that comes to mind anyway.
