holding the associated mutex while signaling a condition variable isn't
necessary and in some implementations will reduce performance as the
woken thread may test the mutex, fail and go back to sleep.

We saturate the result to [0..255]
It's the easiest and safest, given the wide variety of scaling
range we cover: we're not using floats, so precision is always
an issue at one end or the other of the scaling spectrum.
we also use:
round(a - floor(b))
instead of:
floor(a - round(b))
to handle difficult cases (ratio ~= .99, e.g.)
MIPS code is still disabled (and wrong)
