 It seems that the works on animated GIF has completely broken support for
 GIF as individual images.

 What do you think would be the proper resolution here?

 The only good option, in my opinion, would be to allow `image2` to output
 individual GIFs again, with the proper codec – just like it auto-selects
 JPEG and PNG properly. The functionality for writing a non-animated GIF is
 there anyway.
