[ODE] A question about multiple geoms for one body

[Shamyl Zakariya]

Should I be using dGeomSetOffsetPosition and its friends?

I never knew about those methods since I've always used <http:// 
ode.org/ode-latest-userguide.html> for documentation, I didn't know  
about offsets until I found it on the wiki.
