- adapt the bunny scroller to widescreen images.

Browse source 
This only concerns the actual horizontal scroller. The vertical one still needs work and the "The End" screen only works if the second picture of the scroller is the full widescreen image because this page is done as a regular single image page which does not know anything about widescreen asset replacements.
