This allows setting window specific images.
Also Changed:
- The colored background is _always_ drawn, to prevent non-fullscreen
images from leaking information.
- Added function list_arbitrary_insert, which allows insertion to a
list at an arbitrary location less than the capacity. It silently
fails otherwise.
