Physics and Game Play Improvements

Using a corkscrew or loop-the-loop track allows artists to create much more interesting tracks. Unfortunately, this kind of track was not considered with the original game design. Some preliminary work has been done: in our current development version is it possible to change the gravity of a kart depending on its terrain, so karts can drive on the wall or ceiling. But many more features need to be added to make this useable in a game:

Those changes are significant, and it is expected that a significant number of classes need to be improved to handle this.

More physics improvements are of course possible:
