Quite - and then there is the meme about upping the limit improving
performance ;-)

Right - someone gave up on auto-detecting the right options.

Right; so there are some complexities here, but probably nothing that
we cannot address.
My first wonder is: is it -really- slow to re-load the images as/when
we need them ? [ or when the come 'near' the visible region ] ?

Right; Mozilla has exactly the same problem - though it is not that
clear to me that they do a wonderful job there either - but we should
definately look at that code too.
Could you add a (not very easy - ie. at the bottom) hack to investigate
this, and reply CCing Taras Gleck with the link - he is the Mozilla I/O,
memory, performance genius :-) and can no doubt help us find whatever
piece(s) of code we could re-use for this.
Incidentally - the process of finding bogus, obsolete and/or
uninteresting settings is a really good one. I would love to see them
triaged into:
* commonly useful [ ie. stay exposed ]
* useful but not-so-useful [ ie. for an advanced config UI ]
* non-useful compromises that should be removed (cf. above)
Anyone interested in picking that up ?
Thanks,
Michael.
