-  Where the ownership of touches is registered.
-
-  Singleton used for adding a touch point ownership model analogous to the one
-  described in the XInput 2.2 protocol[1] on top of the existing input dispatch logic in QQuickWindow.
-
-  It provides a much more flexible and powerful way of dealing with pointer ownership than the existing
-  mechanisms in Qt. Namely QQuickItem::grabTouchPoints, QuickItem::keepTouchGrab,
-  QQuickItem::setFiltersChildMouseEvents, QQuickItem::ungrabTouchPoints and QQuickItem::touchUngrabEvent.
-
-  Usage:
-
-  1- An item receives a a new touch point. If he's not sure whether he wants it yet, he calls:
-        TouchRegistry::instance()->addCandidateOwnerForTouch(touchId, this);
-        touchEvent->ignore();
-     Ignoring the event is crucial so that it can be seen by other interested parties, which will
-     behave similarly.
-
-  2- That item will then start receiving UnownedTouchEvents for that touch from step 1. Once he's
-     made a decision he calls either:
-        TouchRegistry::instance()->requestTouchOwnership(touchId, this);
-     If he wants the touch point or:
-        TouchRegistry::instance()->removeCandidateOwnerForTouch(touchId, this);
-     if he does not want it.
-
-  Candidates are put in a priority queue. The first one to call addCandidateOwnerForTouch() will
-  take precedence over the others for receiving ownership over the touch point (from now on called
-  simply top-candidate).
-
-  If the top-candidate calls requestTouchOwnership() he will immediately receive a
-  TouchOwnershipEvent(gained=true) for that touch point. He can then safely call
-  QQuickItem::grabTouchPoints to actually get the owned touch points. The other candidates
-  will receive TouchOwnershipEvent(gained=false) and will no longer receive UnownedTouchEvents
-  for that touch point. They will have to undo whatever action they were performing with that
-  touch point.
-
-  But if the top-candidate calls removeCandidateOwnerForTouch() instead, he's popped from the
-  candidacy queue and ownership is given to the new top-most candidate if he has already
-  made his decision, that is.
-
-  The TouchRegistry cannot enforce the results of this pointer ownership negotiation (i.e.,
-  who gets to grab the touch points) as that would clash with QQuickWindow's input event
-  dispatching logic. The candidates have to respect the decision and grab the touch points
-  themselves.
-
-  If an item wants ownership over touches as soon as he receives the TouchBegin for them, his step 1
-  would be instead:
-        TouchRegistry::instance()->requestTouchOwnership(touchId, this);
-        touchEvent->accept();
-  He won't get any UnownedTouchEvent for that touch as he is already the interim owner (ie, QQuickWindow
-  will keep sending touch updates to him already). Eventually he will be notified once ownership has
-  been granted to him (from TouchRegistry perspective), from which point onwards he could safely assume
-  other TouchRegistry users wouldn't snatch this touch away from him.
-
-  Items oblivious to TouchRegistry will lose their touch points without warning, just like in plain Qt.
