Hi,

Sorry, there was a (slight) error with 512x256 residual coding in the
decoder.Now that's ok.

> For the lower quality settings, will have to improve the -l3 setting
> first, raise the quantization to something like 0.82 for example for -l3
> and -l4 settings, and better select/remove the wavelet coefficients.
