/// Best not to use this loop since it has a tendency to

/// simple is either through setInterval in Javascript:
/// https://www.w3schools.com/howto/howto_js_animate.asp
/// or through the Timer API in Dart, especially
/// with Timer.periodic(16, callbackFunction);
/// To see how I got it running for the example,
/// see file 02-AnimationFrameWhile.dart
