Torbjörn Andersson d010b9e560 As an experiment, expire SCREEN_FILE resources faster than other resources.
They're generally the largest resources in the cache by far (though some
ANIMATION_FILE resources are about as big).

I still don't know how much benefit there is to resource caching, but some
of it is definitely needed, or the game won't work properly. Oh well, as
long as no one complains about the extra memory usage...
