[ODE] Geometry passing through TriList

[Erwin de Vries]

This can indeed happen. The maximum stepsize you can take for the collision
detection to give accurate results is "(Diameter / 2) / Velocity" The / 2
part will be fixed in the upcoming release. So a sphere with a diameter of
10 units and a velocity of 1000 units will require a stepsize of (10 / 2) /
1000 = 0.005 seconds

The ray collision has nothing to do with this. In step N objects might not
collide, and in step N + 1 the collision might have taken place in the
meantime, but that is not simulated. It would be possible to fix this of
course, but it is not on my list.
