display_manager ->initialise:

Create the manager. Called once at boot to build @display_manager; not used directly.

display_manager ->append: display

Attach a new display to the manager. Called by display’s constructor; applications normally do not invoke this.

display_manager ->redraw:

Flush all pending changes to the screen. Called from the top-level event loop to repaint windows queued in @changed_windows; may be overridden for special event-loop hooks.

display_manager ->has_visible_frames: keep_alive=[bool]
