Just in case not everybody around here knows, there is an interesting library for vectors, matrixes and quaternion which is candidate to Boost.
I am _not_ suggesting any kind of standardisation related to this library, but I think it's
an interesting data point (among a lot of others) for solving the geometry modelisation problem
related to IO.
I believe that a specific set of concrete types should be standardized for graphics geometry (at least),
but having some observable experience of concepts on which to rely on to build algorithms around
is very useful and Boost.QVM seems to explore that direction.
Of course there are other interesting libraries but they have been mentionned here already
so I just want to complete the data.
