We are not going to make that distinction for GIMP and
keep *one* folder instead, because we tell people all
the time to get a "clean" install by moving their
GIMPDIR away, and we're not starting to tell them
to move two folders away.

We are going to move the caches to XDG_CACHE_HOME
for 2.10 tho.

See below for how I see things currently, please comment
if I make no sense.
