the oldest input sample passed and in[n-1] was the latest. Now it is the 
contrary. This allows making backward_filter() somewhat simpler.

backwards (output[i] == sb[N-i], where N is the buffer length).

This makes the code slower, this will be fixed in my next commit.

than the st{1,2} buffers. My guess is that the original coder decided to 
add one to the array sizes "just to be sure".
