 // LongPressAffordanceHandler displays an animated affordance that is shown
 // on a TAP_DOWN gesture. The animation sequence consists of two parts:
 // The first part is a grow animation that starts at semi-long-press and
 // completes on a long-press gesture. The affordance animates to full size
 // during grow animation.
 // The second part is a shrink animation that start after grow and shrinks the
 // affordance out of view.
