Dismissing the splash screen

With the SDL2 bootstrap, the app's splash screen may not be dismissed

immediately when your app has finished loading, due to a limitation

with the way we check if the app has properly started. In this case,

the splash screen overlaps the app gui for a short time.

You can dismiss the splash screen as follows. Run this code from your

app build method (or use ``kivy.clock.Clock.schedule_once`` to run it

in the following frame)::

This problem does not affect the Pygame bootstrap, as it uses a

different splash screen method.
