The loading dialog needs to be shown while the plugins are being
loaded, so the dialog can't use any of the plugins to display those
images.

I believe the loading dialog uses the image loaders from gdk-pixbuf
(which is a library that GTK+ depends on). If you wanted to add apng
support to the dialog, you'd need to add support there instead.
(There might already be apng loaders for gdk-pixbuf somewhere out
there, I haven't checked)
