If omitted, the screen is cleared; otherwise it should do that itself.
In order to make a see-through dialog, call ``self._native.parent:render()``.
In order to make a dialog where portions of the parent viewscreen are still

If artifacts are left on the parent even after this function is called, such
as when the window is dragged or is resized, any code can set
``gui.Screen.request_full_screen_refresh`` to ``true``. Then when
``screen.renderParent()`` is next called, it will do a full flush of the
graphics and clear the screen of artifacts.
