Still it seems that the general vector functions is a subset of the
functions for 3-vectors.

I did a linear algebra library myself (
including quaternions, cross product, etc. The code for the basic
vector operations is the same for the fixed 3-vector and the general

I didn't benchmark it against other libraries, but as for fixed size
vectors the dimension is a compile-time constant, optimal optimization
seems to be a quality-of-implementation issue.

For the rest I claim that raw pointers must be abolished.
