 This has nothing to do with the license. Its simply that we need a
 internal scaler. Delegating scaling to a external library is not an
 option. It causes problems with self tests, complicates dependencies and
 others.

 If you consider bugs related to the internal scaler unsalvageable and bugs
 related to zscale "release blocking", thats your choice.

 Also haasns swscale work is funded by STF currently. So i think swscale
 will improve significantly within the next months.

 Last but not least, the CC wanted to ban you (Balling) indefinitly in
 march as you probably know. And it was me who stopped that.
 If you want to convince me that I made a mistake, you are doing a good job
 of that
