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

> Hello,
> Just a very quick message to let you know that I have added a higher
> quality setting (-h2, +10Ko) and I have added now residual coding on the
> 512x256 wavelet image for the higher settings.Precision is a little
> better.-I also still apply the post-processing function on the 512x256
> wavelet image for now.-

> 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.
> Many thanks,
