Visible; focused; foregrounded

The Started state; this should roughly correspond to a "focused application" in a traditional window manager, where the application is fully visible and the primary receiver of input events.

Previously called paused

Visible, unfocused; foregrounded

This should roughly correspond to "unfocused application" in a traditional window manager, where the application may be partially visible.

Previously called suspended (and preloading)

Hidden, unfocused; backgrounded

This is a intermediate state between blurred and frozen.

This should roughly correspond to "minimization" in a traditional window manager, where the application is no longer visible. However, the background tasks can still be running.

Previously called suspended

Hidden, unfocused; backgrounded

In the Frozen state, the application will be resident, but probably not running and has no network access. The expectation is that an external system event will bring the application out of the Frozen state.
