[ODE] Added-mass

Hi all,

Is there a possibility to attribute different mass values to the same
rigid-body for different directions? This is the case for lighter-than-air
vehicules (or submarines) that accelerate a non-negligible air mass with
them. The apparent mass is thus dependent on the geometry of the hull and
different for each directions Ox-Oy-Oz. Instead of having one mass m, we
have mx!=my!=mz.

It seems that dMass doesn't support this, since mass is a dReal. Is there
another way of setting masses?

Cheers,
