@brief Get the rotation matrix of a placeable geom.
If the geom is attached to a body, the body's rotation will be returned.
Calling this function on a non-placeable geom results in a runtime error in
the debug build of ODE.
@param geom the geom to query.
@returns A pointer to the geom's rotation matrix.
@remarks The returned value is a pointer to the geom's internal
data structure. It is valid until any changes are made
to the geom.
