With gaze mode and POINTER_HANDS on, the gaze is the pointer and the hand ray
stays off (POINTER_GAZE_HAND_RAY=1 brings it back). A pinch clicks where you
looked 75 ms before ft-hands saw it; held and moved past 4 deg of hand
movement (POINTER_GAZE_PINCH_DEADZONE) it nudges the pointer at 0.3x
(POINTER_GAZE_PINCH_GAIN), and the correction is a gaze lesson. Held still for
POINTER_GAZE_HOLD it's a press the hand drags. A middle pinch right-clicks at
the gaze. One log line per pinch. Rules in pointer/helper/gazehand.h, tested
in pointer/tests/gazehand-test.cpp.
