the corruption checker now checks for certain conditions of the loops of each
sector. Recall that CW loops are outer and CCW loops are inner.
- If a sector has no or more than one outer loop, count that as corruption
(level 4 and 3, respectively).
- (Disabled) For sectors with exactly one outer loop, check that all inner
ones are inside it. This is currently not compiled due to an asymmetry of
loopinside() for degenerate cases, similar to pre-r3898 inside().

When that mode is enabled (see below for caveats), wall textures that have a
non-power-of-two height (call it 'h') will be modified to look like in classic:
Let 'H' be the next power of two greater than 'h'. The texture will be uploaded
with height 'H', made up from 'h' hlines of the original texture, followed by
'H'-'h' first hlines of the same.
No panning "corrections" will take place. The mode is disabled by default.
Caveats/notes:
* the mode requires that r_hightile is disabled
* it is not implemented in Polymer
* in the Lunatic build, it is ineffective when a VX map is loaded, as those

When a map named <filename>.map is loaded (<filename> may also contain directory
separators), the engine checks for existence of <filename>_XX.art in the virtual
file system, where XX is a 0-padded number from 00 to 19. It loads a consecutive
sequence of these ART files, i.e. aborts whenever a number in the sequence isn't
found (in contrast to normal ART loading).
Restrictions:
- the per-map ART files must not reside in ZIP files
- if a tile number is attempted to be overridden that has a dummytile or is
cache1d-locked, per-map ART loading fails
On failure, the map is still loaded, but a diagnostic message is output to the
log/OSD.
Loaded per-map ART data are cleared whenever the map is "left". In particular:
- whenever another map is loaded
- in the editor: when a new map is started
- in the game: after the bonus ending screen of a finished level, after going
to the title screen via the menu
A final note: file names are supposed to be looked up and compared
case-sensitively. That is, <filename> must match EXACTLY between the map's and
per-map ART one; 'art' must be lowercase. Otherwise, the cookie monster will
come and eat you!

The scrollwheel is unique among PC input because it has no innate "hold length". Previously, the layers gave the mousewheel a fake hold length to allow the not-necessarily-synchronous game/editor code to pick up the input before the layers marked it as "no longer pressed". This passed under Windows, but it didn't slide under SDL.
Besides the two problems listed above, it also potentially limited the rate of weapon selection, where scrolling too fast would not register every clicks. [Unrelatedly, this is still the case when you scroll faster than the game's own tickrate, but addressing that would require rewriting input handling to go through a list of "events" for each tic instead of looking at overall pressed/unpressed states.]

The functions mvlineasm1, mvlineasm4 and tvlineasm2 can now be set to clamp
the vertical texture coordinate (vplc), preventing the unsightly stray lines
on the bottom of non-y-flipped sprites. (The first part of this effort, r3483,
handled their top).
However, this is only enabled for the mvlineasm ones: the vectorized variants
suffered almost no slowdown (even though a PADDUSD SSE instruction would be a
nice thing to have), while it was pretty significant for the sequential
translucent ones.
Summarizing, this leaves two cases where stray lines may appear in the non-ASM
build (the saturation is NYI for a.nasm):
- at the bottom of y-flipped sprites
- at the bottom of translucent sprites (can be toggled by #define)
Another observation is that recent GCC generates much faster code for this
stuff than Clang from SVN.

Instead of directly in build.c:app_main(). Previously, it was possible that an

sequence of OSD commands -- where that file is an EDuke32 config file instead!

This commit is more likely to introduce subtle differences in behavior.
Specifically, getpsky() now always returns the default sky properties instead of
the global sky ones (but with all-zero offsets) when no match for a suiting

non-multi-pskies when a global non-default multi-psky has been set up.

- 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...

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.

Toggled with Ctrl+Shift+[KP-]. Variable 'headlight_range' controls its range.
For the implementation, a new event EVENT_PREDRAW3DSCREEN was added.

While the functionality was already internally in place for gametext as one of two hacks using ROTATESPRITE_MAX (the other still used by minitext_() to align with the statusbar) we must codify a bit in the engine for safe external use. (Otherwise, ROTATESPRITE_MAX could/would theoretically increase and leave modders high and dry.)
(Dev note: In G_DrawTXDigiNumZ(), ROTATESPRITE_MAX was used to bitshift the value used to calculate digit spacing for no reason I can ascertain other than to introduce rounding errors into the zoom/textscale calculations. It was never used anywhere, so I removed it.)
Bonus: The scaling code for digitalnumberz and gametextz has been modified so that the spacing is no longer affected by rounding errors. Try animating the zoom value and compare how the text used to jump but now does not.

- Make _buildargv[_buildargc] NULL.
- With SDL layer, pass argv and argc directly and get rid of _build* ones.
- Add tilesiz* to dynsymlists.

If m32script gamevar "move_by_one" is nonzero, the some keys move the
"player arrow" by increments of 1:
- Without SHIFT: LEFT/RIGHT absolute x, DOWN/UP absolute y, A/Z absolute z.
- With SHIFT: DOWN/UP (unbounded!) horiz, LEFT/RIGHT angle.
This can be useful to debug renderer bugs that show a high sensitivity to the
exact location ("are transient in space").

Most of them are already aligned to their natural boundaries, so lowering
the alignment to 1 byte can only worsen things by making the C compiler
generate poorer (unaligned access) code for some platforms.
The layout of structures is not specified by the C Standard, but is rather
given by a particular platform + toolchain's ABI (application binary interface).
Most ABIs follow the expected pattern "alignment of scalars is their size,
alignment of arrays is that of its element type, alignment of structs is the
maximum alignment of its members". A couple of links to particular ABIs are
given in build.h.
Problems are expected with archs that care about unaligned access when a pointer
to a non-packed struct is taken that resides in a packed aggregate, but these
uses should be weeded out (I'm not sure if there are any in our codebase).
The following types are affected, only hitdata_t changes its size:
sectortype, walltype, spritetype, spriteext_t, spritesmooth_t,
struct validmode_t, picanm_t, palette_t, vec2_t, vec3_t, hitdata_t.
