Libswscale and Animated gif were funded ?

Hell, no, that's exactly the point. Nobody will "reimplement" something
that works because of FFmpeg's own interest, except one FFmpeg
developper or one developper from GSOC which was paid thanks to FFmpeg.

Now one company gratefully funded HE-AAC after the project was started
and left over from GSOC, that's great and I wish there would be more,
however it's not done yet, I hope it will be soon, but I don't think
removing libfaad did all help on this, it's still there in the tree and
hopefully it is otherwise you couldn't decode HE-AAC.

I think many developers could be and IMHO should be representative of
FFmpeg credibility. In case you didn't get it, I'll make it clear this
time: replace "myself" by "us". Thanks for your understanding.
