Yes, this is definitely the issue. But do we really need persistent
storage? Think also, that some people run several instances of TeXmacs at
the same time (I hear libelous claims that TeXmacs crashes occasionally
when several windows are open ;) and this may complicate things further
(although admittedly, this multiple instance issue isn't addressed at all
elsewhere).

Why not change that "false" to "true" in the call to cached_load_picture()
inside scalable_image_rep::draw()? No sweating but a great performance win.
Unless there's some hidden issue, of course.
