And you'll see why 30 is the max. 1 << 31 is undefined for signed integers.
There is no particular reason why this would be the largest coefficient
that we want to support (really, our storage type is int16_t for 8bit
content so we can't store these coefficients anyway).
Thanks a lot for looking it up.
I'll amend the commit message with something like "30 is the maximum
number of bits that can be read into coeff_abs below.", and push later, if
that seems ok.
