Fix resizeOnRefresh bug which prevented refresh when film < screen

because `this.run(this.options);` never gets called when film width < screen width, the window resize handler never gets set. this affects both initial load and any refresh states, so resizeOnRefresh will always stop functioning whenever film < screen.

this PR adds the resizeOnRefresh handler in the event that film < screen, and removes the width limit for that example on the demo page so that it's easy to demonstrate and test.
