-// Adding new gesture types involved the following steps:
-//   1) Create a sub-type of SyntheticGesture that implements the gesture.
-//   2) Extend SyntheticGesture::Create with the new class.
-//   3) Add at least one unit test per supported input source type (touch,
-//      mouse, etc) to SyntheticGestureController unit tests. The unit tests
-//      only checks basic functionality and termination. If the gesture is
-//      hooked up to Telemetry its correctness can additionally be tested there.
