End a shot's topspin dip at the bounce, so a kicking ball kicks up

A shot's extra gravity is its dive in flight, but it was carried through
the bounce: heavy topspin skidded away low and Oliver met nearly every
ball 0-25 cm off the grass. After its bounce a ball now falls under plain
gravity (tennis modes only), and every planner that rolls a bounce
forward switches at the same moment. The higher bounces pushed the
auto-run into volleys, so it now takes a kicking ball at the top of its
bounce, up to chest height. Median contact rises from 0.42 to 1.13 m at
the bottom of the ladder. v369.
