I thank all developers and contributors for pc98.

Relnotes: yes
00d578928eca75be320b36d37543a7e2a4f9fbdb 27-May-2016 grehan <grehan@FreeBSD.org> Create branch for bhyve graphics import.

bebb40faf6a18df5c296c5a2f293ceceff15289b 02-Jan-2016 des <des@FreeBSD.org> 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.
11d782769ff19b67410281362ae83a056498d6fd 01-Jan-2016 des <des@FreeBSD.org> 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(). Happy New Year!
