fashion. Among other things, this makes the FOV widening when shrunk
work. User CON code should always check the initial viewingrange value
when attempting to do FOV effects like zoom, because it is not guaranteed
to be 65536 due to different screen aspect ratios etc.

polymer_addlight(). I have no idea whether it's the 'right' thing,
but it fixes this:
Conditional jump or move depends on uninitialised value(s)
at polymer_updatelights (polymer.c:5090)
by polymer_drawrooms (polymer.c:938)
. . .
Uninitialised value was created by a stack allocation
at loadmaphack (engine.c:9482)

This won't actually do anything until the a debug bit is added when
creating the context, but that requires support for GLX_create_context
which SDL doesn't support. I'll add support for WGL_create_context to
winlayer in a bit as a stopgap.

Sprites would stick with their old material on global palette change.
This goes through all prsprites and clobbers their CRCs so that an

The winding order of faces is different if only flipping about X or Y,

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.

Check all the bunch siblings if we get a floor/ceiling hit and walk
them if their own planes hit.

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.

When walking the sectors, put more drawing work between queuing and
reaping the occlusion queries to potentially make them more efficient.

Enumerate the vertical siblings of each walked sector and check them
against the current frustum. No occlusion queries yet, but that should
correct any missing sectors until a flaw in that logic is discovered.

* Mapster32: END modifier to RShift. If it's pressed when RShift is released, sprites which are in grayed out sectors are also selected; Make changing shade affect all highlighted sprites in 3D mode (when aiming at one of them).
* some debug code to watch out for suspicious glGenTexture/glDeleteTextures calls, not active.

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.
Fix a strcpy with identical arguments in game.c and a couple of uninitialized mem accesses related to Polymer lights.

Engine stuff:
* Add 'r_shadescale_unbounded' cvar. When set to 0, OpenGL renderers should never
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

- pr_resetlights() was exported but polymer.c wasn't changed to reflect that. This also broke the gcc build so I'm not sure how this was missed.
- commented code was laying around in the middle of polymer.h
- savegame.c using a bunch of C99 non-constant initializers. Please keep in mind that MSVC is one of the supported compilers and doesn't know C99.
- savegame.c using localtime_r, which doesn't exist on Win32.
- demo playback calling resetlights and drawrooms without ever calling pr_loadboard().
- this change makes the game run very choppy here.
