      Glad you like it. I was mostly trying to fix the claustrophobic  feel

 IMO, it is much nicer for the outdoor maps (still very useful for indoor also),
but really lets you see more of the countryside.  I had thought that objects
should have partial blocking abilities - ie, it would take several forests to
completely block, but a single forest would effectively make things behind it
harder to see (done basically with the lighting code, which means if your in a
forest at night, your light wouldn't go as far either).  Such a change is
unrelated to the one above in terms of technical ability, but a similar
motivation, which was to make more of it visible, was evident.

 The best thing would probably be to have a flag on those objects which us
somthing like 'secret transporter'.

 For non secret ones, the default is to send the coordinates the player moves
(shop mats are such an example, and probably should be the only that have this
on by default).  However, other transporters would send a newmap command.  Map
makers could of course override this - if the map maker knows that the
teleporters he has placed are close enough or the two locations are pretty
obvious, those could also send appropriate offset.

 I notice the teleport function also still has the hard coded values of distance
it searches for use of random teleports (basically, a 5 square square from the
original one).  With the larger map size, this is probably less useful, and this
search range should really be customizable.

 the teleport function itself is in server/move.c, line 197.  transport_ob,
which handles things like trapdoors, is right above that.

      Mark, do you want to extend the pngximage client to do use fog of war?
     
     
 At some point, we should really figure out what of the various image styles we
will support.  I would guess adding support for this in pngximage should be
pretty easy.  Was the above an offer or asking if I would do it?
