{
Stream<Unit> sPressed = sMouse.Snapshot(size,
(e, mSize) => mSize.Match(
s =>
{
MouseButtonEventArgs b = e.Args as MouseButtonEventArgs;
Point p = e.GetPosition();
return b != null && b.ChangedButton == MouseButton.Left && b.ButtonState == MouseButtonState.Pressed
&& p.X >= 2 && p.X < s.Width - 2 && p.Y >= 2 && p.Y < s.Height - 2
? Maybe.Just(Unit.Value)
: Maybe.Nothing<Unit>();
},
Maybe.Nothing<Unit>)).FilterMaybe();
