[ODE] Sliding over a trimesh

So did you actually add support for the edge/vert culling to the box 
code?  My patch will only help with CCylinders until support is added 
for the other types.  I can say that for our game this culling made a 
big difference.  If you can switch your shape from a box to a sphere or 
CCylinder I'll bet it would work a lot better though.  Dragging a box 
over trimesh terrain is just asking for it to catch and flip.

Thanks,

It seems like a good idea, but it didn't stop my box getting snagged on
the trimesh. I just commented out all the code in the collision files
to do with these collisions as a test.

Has anyone got any ideas as to how I can slide objects over a trimesh
without them getting caught on it? Have other people solved this, or am
I doing something wrong?
