Ministats doesn't appear in half the examples

Ministats doesn't work on around half the engine examples.

Well spotted. It turns out mini-stats are missing in examples that use createGraphicsDevice, which is async, and both the device and the app are undefined at the beginning. When the example starts, the setupApp is then skipped.

Lines 187 to 189 in 28d785d

	if (pc.app && pc.app.graphicsDevice.canvas) {
	setupApplication(pc.app);
	}

@ellthompson - any thoughts on how this can be fixed?
