The patch and description are not in sync. The description says that image scrolling happens with one finger touch screen drags and two finger touchpad drags. The only drag gesture subscription call looks like this:
++ grip_gesture_manager_register_window (manager, ++ widget, ++ GRIP_GESTURE_DRAG, ++ GRIP_DEVICE_TOUCHSCREEN, ++ 2, ++ eog_gesture_event, ++ NULL, NULL);
That is, only two finger drags on touchscreens drag the image.
Other than that it looks fine.
