Credit to Plagman for the idea and doing the work on the game side, which is included in this commit.
(Building as C++ will give us features with which we can make improvements and optimizations on the multiplayer code and Polymer.)

Don't call setaspect from them, because the only thing that's needed is
(in classic) yxaspect and xyaspect. Pass these from the helper function
defined earlier instead.

This means that classic and the GL modes now look the same as far as e.g.
hud_bgstretch or HUD weapons are concerned.

Also move a 'int16_t editstatus' declaration from polymost.c to engine_priv.h.

functionality, Polymost).
The new feature can be enabled/disabled with the 'r_tror_nomaskpass' cvar.
The basic idea is that when drawing lower or upper levels, a first pass
is performed that ignores all red walls for which the TROR nextwall link
'towards' the viewer arrives at a red wall. Thus, in the worst case, there
can be up to twice as many rendering passes now (when it is discovered that
the no-mask-pass isn't different that what would be drawn with the ordinary
one, the latter is skipped, since we've already drawn all needed geometry).
Hovever, this kind of multi-pass splitting is only suitable for simple scenes,
like the upper subway in the TROR test map. In particular, multiple islands
shouldn't 'see' each other.
Two issues are worth mentioning: first, care needs to be taken for translucent
ceilings or floors, since drawing them twice isn't the same as drawing them
once. This is done for classic, but not for Polymost. Second, sprites (which
are always drawn _after_ the geometry for a given pass) are still clipped to
the geometry of the ordinary pass, resulting in their disappearance from
certain angles.

Additionaly, a change made it into this commit that fixes redundant collection
of sprites in TROR:classic/Polymost.

dealing with sectors on the two sides of a bunch. Make yax_globallev and
yax_globalbunch variables non-static.
Rewrite a TROR-related bit in the engine code using the new function.

Usage: For an ANM file <somefile>.anm/ANM, EDuke32 looks for <somefile>.ivf, which is the VP8 stream transported by an IVF container. It can be extracted from a WebM file with e.g.
mkvextract tracks <filename>.webm 1:<filename>.ivf
(part of Mkvtoolnix, the Matroska toolset)
Libvpx is required, and the 'YUV'-->RGB conversion is implemented using a fragment shader, so it's for OpenGL modes only. Also, this commit doesn't enable the code.
Unfinished: sound, aspect correction for fullscreen w/ non-square pixels, ... ?

Make MAXNODESPERLINE in engine_priv.h actually a macro that depends on MAXYSAVES and MAXDIM instead of using the obsolete precomputed value. I think this might have been the cause for the latest patched-up overhead view crash.

* rudimentary TROR support
* free mixing of multi- and single-tile pskies
* Don't cull models behind you. That is, treat them like floor sprites in that respect. This way large models like corpses don't disappear from the view unexpectedly.
Classic:
* tweak the last row and column of the translucency table so that e.g. a transparent sprite against a FANSPRITE wall doesn't show up purple (only if Duke3D table is found)
Misc.:
* fixes TROR-nextwall corruption when deleting sectors
* tile selector 'goto' now has also completion
* I forgot a file for the non-OpenGL build last time
git-svn-id: https://svn.eduke32.com/eduke32@1892 1a8010ca-5511-0410-912e-c29ae57300e0
* support for free mixing of multi- and single-tile parallaxed skies in classic
* make visibility independent of yxaspect and viewingrange in OpenGL modes
-- editor:
* when dragging walls, restore pixel width after that (only for the left and right walls of pointhighlight, and its nextwalls, if any)
* pasting on walls and auto-aligning them now carries over a few more fields
-- fixes:
* visibility in OpenGL modes wasn't incremented gradually (regression due to making 'clamp' an inline function instead of a macro)
* memory corruption due to calling qlz_compress with less than the recommended surplus storage of 400 bytes
* decorative sprites in the mirror showing non-flipped
* make the subway SE message (much) more helpful by showing which sector the game considers to be the track sector

* Polymer light access to m32script (light[<lightidx>].<field>). As an application, provide a state 'insertlights' that takes the currently active lights and puts them into the map as SEs (e.g. for maphack recovery).
* Prototype of a mechanism to gray out certain portion of a map, making them inactive to various, but not all, editing operations. Highlighting a set of sectors and pressing Ctrl-R will make the Z bounds be [(least ceiling z), (greatest floor z)] of all selected ones, pressing Ctrl-R when no sectors are highlighted will reset them. Not sure if it's for production use at this stage...
* The 'align walls' feature [.] now has three independently toggleable behaviours: recurse nextwalls (toggled when Ctrl is pressed), iterate point2s (disabled when Shift is pressed), and also copy pixel width (toggled when Alt is pressed).
* Make shades clamp instead of overflowing in the editor
Fixes:
* crash when carrying out certain operations on walls with xrepeat 0
* the Pause key on linux. Also make demo recording start on Shift-ScrollLock because ScrollLock alone is too easily pressed when pausing

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
