## Notation:

*   Green text
    *   The name of a test which focuses on the preceding scenario.
*   None
    *   No test exists where the focus is the preceding scenario.
    *   There may be other tests which exercise this scenario, but
                ideally there would be a test in which this is the primary
                focus.

## Targeting:

1.  **If a touch is already locked to a target, keep it.**
    *   **GestureRecognizerTest.GestureEventTouchLockSelectsCorrectWindow**
2.  **If a window is capturing touches, target that window.**
    *   **WindowTest.TouchCaptureTests**
    *   **WindowTest.TouchCaptureCancelsOtherTouches**
    *   **WindowTest.TouchCaptureDoesntCancelCapturedTouches**
3.  **If it's outside the root window, target the root window.**
    *   **SystemGestureEventFilterTest.TapOutsideRootWindow**
    *   **GestureRecognizerTest.GestureEventOutsideRootWindowTap**
4.  **If it's near another touch, use the other touch's target.**
    *   **GestureRecognizerTest.GestureEventTouchLockSelectsCorrectWindow**
5.  **Otherwise, use whichever window the touch is above.**
    *   **None**
