/**
 * Shows how to display a 3D Splash Screen to the user
 * while time consuming initialization of the main
 * screen takes place.
 *
 * The 3D Splash Screen uses Mascot Capsule version 3
 * to render the graphics.
 *
 * If one just tries to display the splash in the startApp,
 * it might not show up at all until the initialization is done!
 * To prevent this separate Threads are used for the Splash
 * and the initialization. The init Thread doesn't start until
 * the splash actually has been drawn to the Canvas.
 *
 * Beacuse the Splash is animated it's important to give the Thread
 * CPU cycles now and then to be able to render!
 *
