From: Søren Sandmann Pedersen <[email protected]>
Converting a double precision number to 16.16 fixed point should be
done by multiplying with 65536.0, not 65535.0.
The bug could potentially cause certain filters that would otherwise
leave the image bit-for-bit unchanged under an identity
transformation, to not do so, but the numbers are close enough that it
there weren't any visual differences.
