Here's what the standard says about quantizerStepSize:
global_gain = 8 bit, unsigned int (0..255)
global_gain = quantizerStepSize + 210.
So it looks like quantizerStepSize can range from -210 to 45.
I tested a few samples, and didn't see anything > 0, but we
probably shouldn't assume this.
A while ago, I added some code that effectively puts the lower bound
at -200 (I didnt know better). I doubt it effects anything, since
values < -100 are almost never used, but I'll change it back to -210.
