John Bowler 6eecfe3886 [libpng16] Fixed simplified 8-bit-linear to sRGB alpha. The calculated alpha ...

value was wrong.  It's not clear if this affected the final stored
value; in the obvious code path the upper and lower 8-bits of the
alpha value were identical and the alpha was truncated to 8-bits
rather than dividing by 257 (John Bowler).
