Dag-Erling Smørgrav 23e6278ed9 Replace the cosine table with a sine table, which (due to the vagaries of
rounding) has better spread.  Implement fp16_sin() to go along with
fp16_cos().  In the rendering loop, switch from addition to subtraction
so the center of the pattern will be a trough rather than a peak.  This
is completely arbitrary, of course, but looks better to me.
