Time for a small update: I have integrated some components from 
playground/games/kolf2, where Box2D integration had already worked.

I'm going a path of slow migration, in which the stepping functions of Kolf's 
own physics engine and Box2D run at the same time. I'm currently testing for 
regressions by changing the ball's velocity between both engines; only that 
engine which carries out the ball movement is relevant for collision detection 
and stuff.

All in all, this is working out very well, but I'm a bit stuck at the moment 
because the ball now interacts with ghost walls. (Seems like I kinda inversed 
the problem: Ball-wall collision was happening too seldomly; now it does so 
too often!) I will not commit anything before I got this sorted out.¹

Greetings
