The DisplayObject.worldRotation value didn't sign the wt.c value correctly, meaning the rotation would be wrong.

The `DisplayObject.worldScale` value didn't multiply the local objects scale into the calculation, meaning the value wasn't a true representation of the objects world scale.

 * Sometimes the browser would cause a race condition where any connected Game Pads were being detected before the callback had a chance to be established. Also sometimes the rawPad references would become stale, and are now checked constantly (thanks @cwleonard #2471)
 * Sound.isPlaying was set to false when doing an audio loop, but never set back to true if it's a sound not using a marker (thanks @TheJasonReynolds #2529)
