3ff46c02b2 Fix the warnings when building with C++, add MSVC C++ build support. This also changes the internal type of lotags, hitags and cstat type fields to uint16_t instead of int16_t to clean up some dubious behavior wherein the code was using a value of 32768 as a flag in these fields for certain types of things, like invisible sprites (using the value as if it was uint16_t) where it was elsewhere checking if the value was < 0 (using the value as if it was int16_t). This change may break a few specific effects if any part of the relevant code was missed when looking for areas that needed to be addressed.
I think there's also a fix for the CON precache system breakage in here (lost it in my local tree when I started getting the C++ build working in MSVC, sorry!)

d66856eeea Polymer: bring the ypanning correction for non-pow2 walls closer to Pmost's, pt2
This changes a constant inside the panning calculation from 256 to 255 (making
e.g. panning 255 and 0 the same in the "San Andreas fault" sign in E1L5) and
uses the correct reference wall for the "do panning correction?" conditional.
Now, the problematic walls should look the same as in Polymost.

dfdcce090b Polymer: factor out wall y panning coefficient calculation.
Non-pow2 wall/mask drawing in classic introduced cases where walls are
drawn "incorrectly" because they were constructed with the old behavior
in mind.  Polymer appears to "correct" for it partially, but doesn't cover
all cases.  Specifically, now we have:
 - E1L1 first inside secret room (5000, 50000): Polymer draws like Duke 1.5,
   classic now draws with an offset.
 - E3L2 near the vault (-20000, 25000): both classic and Polymer draw with
   offsets compared to Duke 1.5, but they're different!

This means that more research is needed into what makes these two cases
diverge, even though both have the same root cause.

!!! Also, mappers should abstain from using non-power-of two textures on
    walls until this issue is resolved in a satisfactory fashion !!!

90e410cf47 polymer: cull sprite lights after computing sprite geometry
This was broken ever since updatesprite() had been forked off drawsprite() and
would cause static lights to never hit static sprites until one or the other

cdafeef732 polymer: fix animations that loop to frame 0
With VBOs enabled, the virtual pointer to the geometry of frame 0 of a model
is always NULL. This was confusing the polymer code responsible for deciding
whether to enable smooth animations or not, which meant that any animation
that would loop to frame 0 would do it as if animation interpolation was
disabled, which looks very choppy.

480690aa1d Fix the Polymer hitches first encountered with Parkade.
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.

b926e2a496 - When saving game, clear all polymer lights before. Not doing this makes
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.
- add 'loaded map hack' messages after some other successful loadmaphack calls

8250e5f3e8 Polymer: add preliminary support for sector masks.
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.

e77548d42a Polymer: Don't draw 1-way walls twice.
Previously they would get counted both as 1-way walls for immediate
drawing and as mask walls for delayed drawing.
