Commit Message:
NEVERHOOD: Fix palette fading
The palette didn't fade all the way to white when using the
shrinking machine, which caused visible glitches. I've verified
against a YouTube "Let's Play" that in the original it did fade
all the way. Whether or not it did it in this exact way I do not
know, but... close enough.
