* Show a dialog when the user first opens the keyboard.

* time. It is useful for giving specific warnings that must be shown to the user before use.
*
* While the splash screen does share with the setup wizard the common goal of presenting
* information to the user before use, they are presented at different times and with different
* capabilities. The setup wizard is launched by tapping on the icon, and walks the user through
* the setup process. It can, however, be bypassed by enabling the keyboard from Settings directly.
* The splash screen cannot be bypassed, and is therefore more appropriate for obtaining user
* consent.
