Ah, it does WebP not VP8. (And I should have remembered that since it uses
libwebp and not libvpx, d'oh!)  It turns out it wasn't showing up in
xpra_launcher with my package because of an unbundling fail.  :-/

I'm applying your patches to our separate python-webm too, BTW.  :-)

Okay, if client-side libvpx-without-swscale becomes a reality one day, please
let me know and I'll enable it.  In the meantime, I'd prefer not to drag in a
libvpx dependency that won't do anything with the Fedora build (and might
mislead people into thinking this hobbled build supports VP8 when it doesn't at
all).

People who want the video-based codecs instead of the image ones (i.e.
everybody) will just have to grab them from that other repo.  ;-)

Thanks a lot!
