Debug draw the raycast

[Haddayn]

All of raycasts happen before or after scene render & physics simulation in my game loop, and aren't visible when debug renderer is turned on.
So, my question is, how do I make the rays visible for at least few frames? It would be really helpful to see what was actually hit by the ray.

you could always draw the debug ray manually if you want to debug it
getWorld()->getDebugDrawer()->drawLine()
