[xiph-cvs] cvs commit: postfish declip.c input.c version.h

[Monty]

  Modified:    .        declip.c input.c version.h
  Log:
  Although the code was accounting for this, the accounting was
  insufficient; round off error meant that a declip operation with the
  trigger set at 1.0 would not trigger properly on positive overrange.
  
  While I was at it, I fixed the positive trigger offset to properly
  correct for input word size and not blindly assume 16 bits/
