dGeomMoved hook

Hello everybody.

I have a lot of bodies distributed through a big world; most of them are
disabled most of the time, which is good. But at every frame I had
iterate through them all, to update the 3D engine scene graph.

I could not find any way to iterate only through the moved geoms, so I
created a function:

dGeomSetMovedCallback(dGeomID, void (*callback)(dGeomID));

I submited a patch here:
http://sourceforge.net/tracker/index.php?func=detail&aid=1813079&group_id=24884&atid=382801


Please let me know if there's any problem (in particular with nested
spaces, I didn't do extensive tests with it).


Thanks
