4627c1c91b lossless_enc,TransformColorBlue: quiet uint32_t conv warning
no change in object code

1955895199 (32-bit, unsigned) to type 'uint8_t' (aka 'unsigned char')
changed the value to 159 (8-bit, unsigned)

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.

ab2dc8939f Rescaler: fix rounding error
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)
