How does GtkImageView perform with big animations? There's a bug in EOG
about very bad performance with big animations (#344731).

I personally think it's something worth considering. I'd like to see a
proof of concept patch. I've just hacked my minimal image viewer to use
GtkImageView and I have to say I like the way it works and performs
(with only 107 lines of C code in the application side!!!).

On the other hand, at some point it would be needed to propose
GtkImageView as a dependency for EOG (and therefore for GNOME). I'm not
sure how receptive the community would be about it (you know, nowadays
they don't want to let much specific libraries in, but to consolidate
GTK+), but I can think of some applications in the desktop which could
benefit from GtkImageView.

Great work dude!
