That is interesting.  I think that the "streaming" APIs that the 
GraphicsMagick WebP decoder/encoder is using would also be used by 
gif2webp.  These APIs come from libwebmux.

In the future when we might support animated WebP then this library 
would definitely be needed.

As to how I deduced, I used 'ldd' on the gm binary to see what shared 
libraries were used.  I would have also known this due to writing the 
configure script and Makefiles.
