Flickable containing PinchArea is unresponsive following pinch.
Flickable containing PinchArea is unresponsive following pinch.

PinchArea was releasing the mouse grab when all touches were
released, causing the mouse release event to not be propagated
to its parents, who were then unable to correct their state.
Remove this code and allow the normal event handlers to do their
thing.
