Gdk PixbufAnimation supported formats

[Kip Warner <kip thevertigo com>]

Hey list,

I'm having some difficulty trying to track down the animated file
formats supported by gdk_pixbuf_animation_new_from_file(). I am using
the function via PyGI / GObject introspection. 

I know for a fact that it supports animated GIFs, but beyond that, I do
not know (e.g. MNG? APNG?). GIF works as a last resort for my purposes,
but the constraint of 256 colours is rather limiting. 

I've tried looking through the Gtk+ source in gdk/* and gtk/*, but
maybe I've just been looking in the wrong places. I also tried looking
through what relevant documentation I could find on the Gdk's C API,
and didn't manage to find what I needed. I'm guessing that perhaps this
is because the actual loading is deferred to some other lower level
external backend to Gdk, such as Cairo, but I'm speaking from
ignorance.

The reason I ask is I'd like to use some simple animation in my Gtk+ 3
/ PyGI application. The animation is really too simple to warrant
Clutter or GStreamer, but enough to at least need basic transparency
and preferably > 8 bit colour.

If anyone has any other suggestions, I'm all ears. Thanks.
