1. `It is delivered exactly once to the source node/scene`: you could probably remove `/scene`, it is implied by the way events work. Maybe be a bit more precise: `It is delivered exactly once to the node on which the press-drag-release gesture was started`.
2. `outside the application` is a bit vague, as applications don't have a spatial extent. How about: `It is delivered even when the mouse was released outside of the window`.
