Feature Freeze Exception:

The utouch stack today operates on the principle that every gesture event has a transformation to be applied about a transformation point. The current libgrip code does not expose the transformation point in the pinch and rotate events.

The proposed change adds the position coordinates to the events. This is a small abi change, but there are currently no users of libgrip in the Ubuntu archive. The regression risk is very low.
