Well, I guessed it was related to math. ;) > > Or to put it another way, there are no constraints, it's not that sort > of system.

I just didn't want to work through the source immediately, searching for a constraint solver's implementation like Cassowary. > > On the other hand, there is also ephysics, which can be used to make > graphics objects react to other objects in a 2D plane using the bullet > physics library.
