====== Full screen mode ======
If you need to use the whole screen for your display, you can enter full-screen mode using
<code JavaScript>app.SetScreenMode("Game");</code>

The screen will automatically revert to normal mode when your app ends.

If you wish to revert to normal mode sooner than that, use
<code JavaScript>app.SetScreenMode("");</code>

There is an older call
<code JavaScript>app.SetScreenMode("Full");</code>
but this is only really useful on older devices
