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

additionally compare the mp2 case with some delay as this matches better (the delay issue obviously should be fixed)

-corrected wrong value in mv data
 -set correct mb_type after adjusting index
 -don't use H263 loop filter when the loop filter flag is set but when
  using the H261 encoder
 -use the same unquantizer as H263 (which is optimized btw)
 -removed unused members in H261Context

finetune bit/distortion weighting factor used in motion estimation, the old coeffs where finetuned relative to incorrect mv_penalty tables which where then fixed later but the coeffs where not
this _may_ fix the long standing blocking artifacts, but may also introduce mudding artefacts theoretically, so please tell us if u stumble across any so we can either fix them or export this variable so the user can change it

fixes the random dts/pts during encoding
asf preroll fix
no more initial zero frames for b frame encoding
mpeg-es dts during demuxing fixed
.ffm timestamp scale fixed, ffm is still broken though

note, dont take the PSNR/stddev values serious, they are caused by a bug in ffmpeg.c which drops one frame before the last frame during encoding with b frames
