Note that fixing requires changing all the functions in image.c that
require a frame argument, so that they use a terminal argument instead.
Otherwise, if you associate image caches to terminals, you run into
problems with terminals that have no frame (e.g. terminals created using
x-open-connection), because you can't supply those image functions with
a frame argument.
