When a PinchArea has multiple child MouseAreas, if a pinch is initiated with the two points over different child MouseAreas, the pincharea won't work.

Attached an example of a broken code.

putting a finger over the two different rectangles, to pinch will be generated. If both are on the same rectangle, we'll get pinchUpdated signals.

putting a big mousearea over both, will fix as well, even if it refuses all events
