Marc Mutz e3e0240c77 QGraphicsScene: prevent lots of detaching d/t editing of copies 
QTouchEvent::touchPoints() returns a const-&, but the old
code took a copy, over which it then iterated, modifying
the touch points, causing (necessary) detaches of both the
list and the touch points.

Befriend QTouchEvent and modify the list in-place, avoiding
all detaches in the likely case that QTouchPoint contains the
only copy of the touch point list.

This is all the more important as the function is called once
for every item-under-mouse in sendTouchBeginEvent().

Port to C++11 range-for as a drive-by.
