A mng loader which only loads the first frame is already available in 
http://bugzilla.gnome.org/show_bug.cgi?id=71267
Mine does incremental loading, though.

But as you will see in the bug, the main problem with libmng is implementing
multiple independent
iterators on the same animation. I personally think that working around this
by copying the whole animation would be acceptable, since
one-iterator-per-animation is probably the 95% case. But 
IIRC, even copying the animation isn't supported by libmng...
