Feature: Only trigger render on device motion update.

[markst]

Rather than creating a timer for rendering (or using GLKViewController timer) what if the CMMotionManager update triggered the next render loop?

Ahh.. I set out to merge the two, having read your suggestion a month ago, and did the exact opposite! I tied the both to the GLKViewController timer, probably because it was more intuitive in that moment, but I'm seeing a benefit to your suggested method is being able to remove the GLKView draw function. is this what you were thinking too?

Either way, great suggestion, I agree that both these functions can and should be tied to only 1 timer.
