gdk-pixbuf:pixbuf-animation-iter-on-currently-loading-frame (iter)

iter -- a gdk-pixbuf:pixbuf-animation-iter iterator

True if the frame we are on is partially loaded, or the last frame.

Used to determine how to respond to the "area-updated" signal on the gdk-pixbuf:pixbuf-loader object when loading an animation. The "area-updated" signal is emitted for an area of the frame currently streaming in to the loader. So if you are on the currently loading frame, you need to redraw the screen for the updated area.
