For both RealVideo 3.0 as well as RealVideo 4.0 the VLC table to use
depends upon the slice's quantization parameter; these are coded on five
bits in the bitstream and are therefore in the range of 0..31; yet the
last element here is not valid and therefore the quantizer is clipped to
the range 0..30 to get the index. But this is unnecessary: One can just
add one element more to the relevant array to avoid the clipping.
