[ODE] Trimesh collision: not all triangles are colliding

Note that the build geometry function takes number of INDICES, not number of triangles.

You could step into the trimesh collider as it's building its representation, and as you're testing against it, to see what's going wrong. Pay careful attention to the bounding boxes of each node, compared to what they're supposed to do.
