The cause was a combination of many factors. First, Polymer requires the
start-drawing position to be inside the sector to draw (deviations lead to
incorrect drawing). This was violated by the game, because it interpolated
the current and next tic position without updating the sectnum, leading to
inconsistencies especially when passing through narrow sectors. Polymer
worked around it by doing an updatesector() each frame, however this works
poorly for maps with overlapping geometry such as SoS or RoR.
The solution to this is to add a new engine function,
updatesector_onlynextwalls(), which searches the sectors (via nextsector)
in breadth-first fashion instead of from 0 to numsectors-1, like updatesector
does when it fails for the *immediate* nextwall neighbors.
Internally, the breadt-first search helpers are moved into the engine.

the SE ones douple, triple, ... after each save. Maphack lights are reloaded
with polymer_resetlights() (though I've had them disappearing after load, I
couldn't reproduce it afterwards).
- in debugging builds, print a message when polymer_resetlight is called on a
nonexistent one. The problem is not so much the call itself (it's guarded),
but the fact that resources on the caller side may not have been freed if it
thinks that those lights do in fact exist. Right now, it's not the case though.

work. User CON code should always check the initial viewingrange value
when attempting to do FOV effects like zoom, because it is not guaranteed

First, if we're in Polymer, don't precache tinted tiles that have a highpal
for that certain pal. Second, don't precache tiles for palnum 251 (the last
non-reserved one, which is used as a crosshair pal). Assuming that there are
no other tints, this cuts the initial precache time and cache size on disk in
half.

In cases where performing occlusion queries for multiple red walls
leading to the same sector, we would sometimes leak a number of
query objects. This was apparently harmless on NVIDIA drivers, but
would leak tons of memory on ATI.

The code was using the Polymer-cached version of the sector cstat to
determine the translucency of its diffuse material, meaning it would
never get it right on the first try; that's what you get for having
completely different variables named 's' and 'sec'.

We normally enable backface culling always, but turn it off for
two-sided sprites; we need to make sure it's re-enabled after that
as sector masks are drawn after.

Some of the ROR code was operating under the assumption that drawasks
always correspond to one call of polymer_displarooms(), but that's not
necessarily the case; external view draws all sectors from the top
polymer_drawrooms(), which was causing crashes. Just ignore the sector
mask queues in external view mode, we already don't draw masked walls.

When walking the sectors in displayrooms, detect floor/sector masks to
place them in a mask queue. The queues are allocated on the heap, but
a stack pointer is maintained by the displayrooms to allow it to play
nice with mirror recursion.
Right now the masks are drawn after all of drawmasks is finished; that
means you can see sprites and wall masks through sector masks, but not
the opposite. There is a slight attempt at blending far to near, but
nothing too conclusive yet; that means that in some cases some sector
masks won't be visible through other sector masks, but it should work
for trivial cases.
The next step would be to copy all the drawmasks logic into Polymer
and have it (attempt to) properly interleave sector masks where they
belong in the blending order.

Previously they would get counted both as 1-way walls for immediate
drawing and as mask walls for delayed drawing.

Assigns the right alpha value to floor/ceiling planes if their
translucency bits are set and make sure that changing the cstat now
triggers an update of the material for editing purposes.
This doesn't do anything by itself, but will be needed to correctly
draw floor/ceiling masks.

First, it is now possible to disable the memcache (which is there to cache the texcache) by setting the new cvar 'r_memcache' to 0. Do this if you're constrained on memory or getting crashes when e.g. doing vidrestart often. Also, the memcache will disable itself (and free its storage, if it's there) the first time it fails to allocate.

draw completely black objects (currently only implemented for Polymost)
Mapster32:
* Add 'r_shadescale' to config
* In 3D mode, make SPACE behave the same as holding down a mose button: the
currently pointed-at object is locked. Required some modification of a.m32
to play well (i.e. not reset SPACE). This is useful by itself but more so
in conjunction with the next point
* make Alt behave as a modifier with PGUP/PGDN: when aiming at a 2-sided wall,
move the other side's sector's ceiling or floor (only this is new).
* Auto-alignment of walls can be controlled in a finer grained fashion now:
When pressing '.', only the immediate neighbors get aligned. Use Ctrl-. for
the old behaviour.
* When inserting a point in 2D mode, auto-align the neighboring wall
