* Updated TODO
* Cleaned up code, removed Triange, Square and Circle classes, and removed SVG library
* Updated TODO to reflect the change
* We're not going to resize the texture, since that would mean having to do complex math to figure out how to transform the cars
* For the above reason, there's no need to port the app to other phones
* Not implementing lighting since it would make little visual difference and add time to drawFrame
* Last thing to do on the TODO is optimize code
