[ODE] Some missing trimesh functions

[Vadim Macagon]

Hi,

These functions are declared in the tri mesh header and mentioned in the ODE
manual, but they don't appear to have been implemented yet :|.

void dGeomTriMeshSetCallback (dGeomID g, dTriCallback *Callback);
dTriCallback* dGeomTriMeshGetCallback (dGeomID g);
void dGeomTriMeshSetArrayCallback (dGeomID g, dTriArrayCallback*
ArrayCallback);
dTriArrayCallback *dGeomTriMeshGetArrayCallback (dGeomID g);
void dGeomTriMeshSetRayCallback (dGeomID g, dTriRayCallback* Callback);
dTriRayCallback *dGeomTriMeshGetRayCallback (dGeomID g);

It would take like 5 minutes to implement them all, so could someone with
dev CVS access please do so.


Cheers,

Vadim.
