As you probably know, the old VBR routine tries to
get an acceptable quantization at different bit
constraints, resulting in something like a binary
search for the optimal bit amount needed.
While its search, after a succesful try it reduces
the bit amount, after an unsuccesful try it increases
the number of bits. So it will find after ~6 tries
a near optimal quantization.
Formerly the quantization loop got fresh scale
factors, so it always builded them from ground up.
Now the quantization loop starts with a scale factor
colouring from the last succesful try.
