LameDuke's shade table has 32 gradients of shade, like Duke3D.
For the translucency table though, only the diagonal + one half is stored
because it's symmetric (50/50 translucency).

Sprites are now considered to have out of bounds sector numbers if it is
< 0 or >= numsectors (not merely >= MAXSECTORS). If such a sprite is now
encountered during post-load, an attempt is made first to assign it a sector
number (using updatesector()). If that fails, the sprite is removed from the
map. The background is that a dozen of maps do come with such sprites and
could previously corrupt the sprite list when loaded.

- Rewrite some sprites-of-{stat,sector} loops using the SPRITES_OF,
SPRITES_OF_SECT and new SPRITES_OF_SECT_SAFE macros.
- In passing, identify some problems and mark them with 'XXX', but don't
attempt to fix them yet.
- The usual readability improvements...

This fixes liztroops not passing TROR layers when on the jetpack, as well as
other enemies capable of moving upward, and also COMMANDER and DRONE (for which
the code is special-cased).

The Lunatic build compiles with new structures for sector and wall types.
They have separate members for TROR {up,down}{bunch,nextwall}, so there are
no conflicts with other uses of members into which they were previously
shoehorned. Also, the maximum bunch limit is bumped to 512 in that build.
Currently, loading from V7/8/9 and saving to V7 and V8 are supported.

Previously, only the <0 condition was checked. However, the passed sectnums
could be >= MAXSECTORS (at least in C-CON), for example when issuing 'canseespr'
on a sprite not in the game world.

This enables ART animations to take effect on voxels in classic, voxels and models in Polymost, and models in Polymer.

This fixes an update issue: start EDuke32 without warping to a map in Polymost,
change to classic, and change to Polymost again. The OSD background will be
displaced.

Face- and wall-aligned sprites are drawn using the wall routines in BUILD.
However, the per-x-screen-coordinate distance (swall[]) is calculated in a way
that potentially incurs great precision loss (for example 5 bits for
xdimen=1280, yxaspect=65536). This leads to the starting (top) vertical texture
coordinate possibly wrapping to large values, leaving an unsightly "stray line"
on top of the sprite from certain viewing angles/horiz values.
The approach to fix it has two parts: first, the distance is calculated using
float values, preventing the precision loss. Because this doesn't fully prevent
the unwanted lines, the texture coords are clamped to the mininum and maximum
(0 and UINT32_MAX respectively) when calculating them for sprites.
Note that stray lines may still appear at the *bottom* of sprites under certain
circumstances, for example when viewing at a y-flipped sprite from above.
These should be less noticable in real-world usage though.
The feature is guarded by a macro HIGH_PRECISION_SPRITE in case using floating
point or 64-bit integers is undesirable/impossible on some platforms.

That is, first check if the sprite is in the game world and then if it
already has the desired sector or status number. This doesn't change anything
in our codebase, since the return values of these functions are never examined.

Whether a sprite is considered for texel-hitscan is determined on the base
tile number, not the individual animated tile numbers.

Also, add another flag, signifying that from the editor, also the
"lastwall"s (i.e. the CCW-linked points) should get collected. This is
to signal the editor that their wall lengths should be displayed, too.

Reproduced as follows (assuming all tiles have texel-hitscan for simplicity):
In E2L5, shoot the opening switch with the shotgun, aiming for the border.
The crash occurs because the *other*, depressed switch tile isn't yet loaded
when we index into its tile storage. Dereferencing 0+small number == BAD!

Unconditionally enabled, but useful for comparing the behavior of the 1-column
vline functions against the 2- or 4-column ones.

The former is really only a workaround. Walls/vertical sprites/pskies with
ysize 512 (and presumably greater, but this was not tested) are rendered
with one shade higher at the borders (1 pixel vlines) because of a certain
assumption in the ASM (see comments there). With very dark shades, the
palookup[] buffer is accessed oob. We simply allocate 256 bytes more at the
end for each.
The latter is only for CLASSIC_NONPOW2_YSIZE_WALLS builds, which is not enabled
yet. It seems to matter only for the uncommon case where the such pskies repeat
in the height. A 1680x1050 window fully covered with such a sky is then rendered
at about 60/85 the FPS for me (mostly due to not using the 4 pixel vline
routines), so it may be leaning a bit too much on the side of correctness.
A compilation switch DEBUG_TILESIZY_512 is introduced in engine.c for
demonstration purposes.
