during encoding.

     *     Offsets can be fractional; they are added before QPs are
rounded to integer.
     *     Adaptive quantization must be enabled to use this feature.
Behavior if quant
     *     offsets differ between encoding passes is undefined.
     *
     *     Array contains one offset per macroblock, in raster scan
order.  In interlaced
     *     mode, top-field MBs and bottom-field MBs are interleaved at
the row level. */

     *     Useful if one wants to use a different quant_offset array
for each frame. */
