Keep the racket in one hand through the wind-up

Oliver, off the file browser: "the racket changes the hand in 3 and 4". It did —
the generator drew frames 1-2 right-handed and 3-4 left-handed. Both mirrored into
line with the rest of the serve (a back-view figure mirrors for free), and the
batch prompt now names the side, since the generator will not hold a prop in one
hand across a sheet unless told to.

The convention the rest of the art already uses: racket on the LEFT-HAND SIDE OF
THE IMAGE, free arm on the RIGHT — the side the game drops the bounced ball and
tosses the served one. p_smash keeps the racket on the right: that is the frame
where it has come over the top to meet the ball it is hitting.
