Hi,
Closure currently loads GIF files by saving the contents to a
temporary file, running gif2png on the file, then slurping in that
file. The attached patch (well, it isn't packaged as a proper patch)
allows Closure to load GIF files directly, thanks to Zach Beane's
Skippy library.

Interlaced GIF files are not currently supported by Skippy (but this
should change shortly). Only the last frame of animated GIFs will be
displayed (yes, this is a feature).
