maybe fixed textures for floor and ceiling? not sure because somehow the
material got messed up - need to revert to see if it gets fixed.
Branched some stuff into new files, and put those into sub-directories.
Meta files moved appropriately. Also, began getting corridor cube
placement working. For the meantime, I'm just placing the outer-most layer
of cubes, because I'm hitting pretty terrible performance issues w/o it.
Seems like it may be manageable to extend, though.
Due to problems getting things to work correctly, I've decided to just
inflate the rooms a bit and get rid of random stretching. The stretching
isn't terribly noticeable most of the time, anyway. Also, beginning to put
in cube placement culling. It's far from complete (right now, it's just
skipping cubes that aren't visible, for the most part), but it's a good
start. Short note: somewhat concerned about performance on this, because
it has to enumerate over so many lists. So far, I can't tell terribly
whether a lot of time is getting eaten up with this, but it's worth
considering.

Anyway, next objective: put outside corners connecting rooms, and begin
looking into corridor branch rooms.
