[osg-users] how to clear Vec3Array

It is "detaching" the memory. There is no guarantee the memory is 
actually freed at this point (see std::vector)
The only safe way to "de"-allocate a std::vector is to get it out of 
scope or swap it with an empty vector.
Note that for c++11 there is also a shrink_to_fit.
