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

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.

17 years and change after I wrote warp_saver, here's a simple plasma effect
(currently only three circular patterns) which requires quite a bit of
fixed-point arithmetic, including sqrt() and cos().
