The rounding done when converting to smaller sample widths fails for
saturated positive samples; in this case, the sample value overflows and
becomes negative.  We are better off without rounding, even if we then
have quantization noise (of at most half the resolution of the least
significant bit).

6329db3af1 Improve the sample conversion in plug layer
Improve the sample conversion in plug layer for the sample bits
reduction.  Use round instead of truncating, which introduces
more quantization noise.
