/** A component for showing a splash screen while your app starts up.

    This will automatically position itself, and delete itself when the app has
    finished initialising (it uses the JUCEApplication::isInitialising() to detect
    this).

    To use it, just create one of these in your JUCEApplication::initialise() method,
    call its show() method and let the object delete itself later.

    E.g. @code

    void MyApp::initialise (const String& commandLine)
    {
        SplashScreen* splash = new SplashScreen();

        splash->show ("welcome to my app",
                      ImageCache::getFromFile (File ("/foobar/splash.jpg")),
                      4000, false);

        .. no need to delete the splash screen - it'll do that itself.
    }
