Feature Request: Animate render operation

[tiger12506]

Add to the renderer the ability to animate the operations at 100% speed or faster.

Since render currently draws at a particular time step, I don't think this would be difficult to achieve. Add some UI elements (a speed slider, Play/Pause, Stop buttons) and set up Timers that set currentTime variable and then draw.

I will attempt to figure out the code-base and create a pull request.
