While adding stereo rematrixing, I came across something that needs to
...
be fixed even without adding the feature. The output correctly uses 4
dummy values for the rematrixing flags in block-0, but the bit
allocation routine does not take these bits into account. From what I
can tell, there was a patch in 2003 that corrected the output to make it
DVD and spec compatible, but it didn't correct the bit allocation. It's
only 4 bits over the entire 6 blocks, so overflow errors would happen
rarely or never, but it's still worth fixing. So here is a fix.

increasing precission of the quantization parameter
...
this is needed as the quantization stepsize for each subband is also in this precission and insignificant changes to the wavelet like scaling its coefficients slightly differently would lead to wildly variing PSNR and bitrate
note, a encoder could also simply choose to leave the least significant bits of the quantization parameters zero which would give the exact previous behaviour except a y very tiny number of bits in the header
