[theora] NHW Image codec

[Raphael Canut]

Hello,

Ok, and that's too many work to review a source code.In my codec, I have 3
compression schemes, I think 2 are not patented, but the third... I don't
know.For the rest, I think my codec is patent-free (I don't use
SPIHT,EZW,zerotree methods), even the wavelet transform is new and don't
use the lifting scheme nor the convolution product.

Else, if you found time to review the codec, do not hesitate to let me know
what you think of it and if you would have remarks.Would be much
appreciated.

Cheers,
Raphael
