07426ccc2a Polymost: fix mirror-related oob access analogous to r1872's fix for classic.
When drawing from inside the mirror, there may be no 'bunches' (BUILD lingo,
not TROR ones) collected, but following code used the first one unconditionally.

50375fcff2 Fix apparent horizon not being independent of viewingrange (classic/Polymost).
The apparent horizon (in units proportional to pixels by a constant factor)
was being calculated without normalizing to viewingrange, resulting a
discrepancy between the drawn and actual up/down angle with non-default
viewingranges (e.g. with r_usenewaspect=1, or when setting it from setaspect).
This also means that the center-of-aim will now be the same regardless of
the aspect.

This fixes many derived bugs:
 * inconsistency w/ crosshair when shooting a gun and aiming up/down (obviously)
 * bugs resulting from being able to look up/down too far (garbage non-slope
   texture-mapping and viewing BIGORBIT skies above the borders in classic).

Note: mods that had workaround logic for this bug will have to remove it...

80bd1bb4e4 engine: make neartag accept a sprite-blacklist function and use it in sector.c.
Internally, the last argument to neartag is now a pointer to a function
  int32_t (*blacklist_sprite_func)(int32_t i),
which is supposed to return 1 if sprite[i] should NOT be considered for hitting.

This is now used in the hard-coded neartag() calls in sector.c, but not in any
way in CON (there's neither a C blacklist function provided, nor is there a
possibility to define one in CON).  There, all sprites with picnums >=1 and <=10
(i.e. the effectors) will be blacklisted.  This remedies problems where such
sprites would get in the way of switches.

Note that a whitelist approach (only consider a predefined set, namely those
picnums which will be checked afterwards) has back-compatibility implications
since people may have used e.g. lotagged window sprites to cover a switch.

Also, the >=1 to <=10 range is [sic] (the static, not dynamic values are used),
since anyone redefining effector picnums is clearly out of their mind.

0ef1721955 Mapster32: Fix extended ceiling/floor picnums taking on picnum 0 in Polymer.
The reason was that drawmasks(), which was where the resetting of the fake
RoR textures happened under Polymer, can be called from polymer_displayrooms()
when mirrors are present. I was assuming that drawmasks() was only ever called
after the 'main' drawrooms and that hence the sequence of fake RoR tile tweaking
was set, reset, set, reset, ... which it was not.
Now, do the resetting explicitly after every drawmasks() in the editor.

30e16fe7bb When loading a map in-game, clear TROR wall members corresponding to up/down links.
I find this cleaner for two reasons.  First, lotags won't get in the way of
neartag(), so that doors and switches near constrained TROR walls can be
pushed.  Second, this removes the information leak so that CON coders aren't
tempted to read that values directly before a proper API for that comes along.
When writing out a map in-game (e.g. with dndebug), restore the respective
members so that it can be loaded in the editor again.

00b852fe37 EDuke32: When in menus, always draw a black (33%) translucent background.
Internally, there's a new function fade_screen_black() that implements the
fading more efficiently than calling rotatesprite for classic, and uses
tile 0 (assumed to have at least 64x32 size) in the GL modes.

The black background of the user map selector is still done with rotatesprite
and tile BLANK in every renderer.

d0acd40ff8 Inreased debugging level for catching oob accesses to 'main' arrays.
If enabled, this makes the following arrays be allocated statically:
spriteext, spritesmooth, sector, wall, sprite, tsprite, while
necessarily disabling the clipshape feature (because it relies on
setting sector/wall to different malloc'd block temporarily).

To compile, pass DEBUGANYWAY=1 in addition to RELEASE=0 to 'make',
and it's really only useful with CC=clang, of course.

340b2f7647 Increase the number of maximum art files from 64 to 256 and tweak loadpics().
It is likely that this is the value it used to have at some point, because
the MAXTILEFILES macro equals 256 and is as old as the Duke3D source.
loadpics() now refuses to load an ART file with localtilestart or localtileend
out of bounds, or if localtileend<=localtilestart (i.e. no tiles in ART file, or
nonsense). Also, on 'invalid art file version', continue instead of returning.

Note: this does not increase the maximum number of tiles, which is still 15360,
it only gives a bit more freedom to arrange them (well, into more art files).
Also, I don't see what anyone keeps off from packing any number of tiles (from
1 to 15360) into an art file. Old EDITART limits?

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.

8ec15480c0 Besides the performance issues, there's another reason why changing the palette
'frequently' isn't such a good idea.  Assume an actor constantly changes the
palette to some value and you're attacked by a newbeast at the same time. Then
the pain tinting would be reset each time the actor's code is run.  This commit
adds a new flag 16 to setbrightness(), meaning "don't reset the fade tinting".
Its only use right now is from CON's setgamepalette command (and there, always).
The change is done in the engine and thus affects all platforms.

This requires certain t_data[] entries ([1]: move ptr, [4]: action ptr and
[5]: ai ptr with actors) to be converted to script offsets instead of pointers,
breaking savegame and net packet compatibility (we could in theory try hard not
to, but it would be too much trouble).

9b0ea0366e Add new actor[].flags flag 2048 (SPRITE_NOCLIP), for 'spriteflags' CON usage.
Actors are always moved such that _they_ clip against blocking sprites, even
if their blocking bit is clear. Setting the new bit make them not clip against
anything.  The promary use of this is for decorative moving sprites that are
spawned in masses, such as rain or snow.
