onTertiaryLongPressDown property
getter/setter pair
Called when a pointer has contacted the screen at a particular location with a tertiary button, which might be the start of a long-press.
This triggers after the pointer down event.
If this recognizer doesn't win the arena, onTertiaryLongPressCancel is called next. Otherwise, onTertiaryLongPressStart is called next.
