[ODE] dGeomTriMeshSetCallback / dGeomTriMeshSetArrayCallback

[Colin Bonstead]

I was just looking at the code for those callbacks in the 
CCylinder-Trimesh collider recently.  In that case, a bounding box (I 
can't remember if it was axis or object aligned) is collided with the 
trimesh.  Then, each of those triangles are tested against the actual 
CCylinder.  So, what's coming through the callback is a *potentially* 
colliding set of triangles.  What exactly are you trying to use the 
callbacks to do?

Update after a few investigations:
I've added dGeomTriMeshSetCallback support for spheres (see attached 
patch), and now the problem is the same for dGeomTriMeshSetCallback and 
dGeomTriMeshSetArrayCallback:
Collider.GetTouchedPrimitives() is reporting triangles that are not 
**really** touching my Geom. (see picture in my last post)

Am I using TriMesh wrong ? Is it normal ?

PS: I'm using very last ODE snapshot.
