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.

Meaning that only *ettsprite[THISACTOR] makes sense from CON. It did before
too, because .tspr was set before each event run (and not before all runs),
only that it was never nulled, which was kind of untidy.

Its only use is to have a actor -> tsprite mapping for the EVENT_ANIMATESPRITE
event and .tspr will be set before it is run.

The m32script variable 'showrespawn_always' toggles whether the respawned picnum
is shown unconditionally instead of only when aimed at (and locked onto the
RESPAWN sprite) in 3D mode.
Cool idea by Micky C.
NOTE: sometimes doesn't work because of a bug in the m32script interpreter.

Use a new flag to mark hard-coded enemies, not SPRITE_BADGUY.

The pixel doubling now only applies to the area where the world scene is drawn,
i.e. it may be smaller than the physical screen / WM window size. The optimized
version is slightly faster than for non-doubled pixels for me (optimized build),
but see code for caveats. Some other minor issues:
- won't work when the world is drawn from demo cameras (and offscreen, but that
matters less)
- will leave a few pixels empty when running with x resolutions not evenly
divisible by 4

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

* Make the "classic status bar fullscreen viewport" mode accessible
in classic too.
* Make range of status bar scale 36..100
* Update ud.statusbarmode when executing OSD command r_size (ud.screen_size).
NOTE: ud.statusbarmode is considered internal. Don't use from CON!
* Make sure 1) loading any configuration and 2) menu bars work correctly.
(The "classic status bar fullscreen viewport" mode will never be restored
though because ud.statusbarmode isn't handled by the OSD var system).

One use was in determining the ray vector for the mouse-aiming hitscan
in the editor. Unfortunately, the change doesn't make it any less broken
in Polymost, even if the two instances were out of sync.

If enabled, dragging wall vertices will correct the xrepeat after the
mouse button is released, so that the pre-drag absolute stretching is
restored.

- Run it twice, since the first one is wrong.
- Warn when attempting to align based on a top-oriented wall. When the
sequence of walls to align has "windows", only the bottom parts will
be correct.
- Make the modifiers actually useful:
* Pressing SHIFT aligns at most one wall, remove the old CTRL modifier.
* The rest is as before: ALT makes the walls have (approximately) equal
texture stretching, ['] (quote) aligns the immediate TROR-nextwalls.

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.

This is done by introducing an additional internal bit, meaning
"play only one instance". It is set for all sounds which have bit 1
("repeat in the sound system") set at definesound time, but not those
that set bit 1 temporarily (see r3336).

- Stop using memcache on some other failure paths, particularly when
failing to read from the on-disk texcache.
- Factor out cache reading code (3x).
- Fix endianness issues affecting big-enadian systems (one introduced by
r3382, one existing before). Comment each B_LITTLE32 with whether we're
converting from native to on-disk (little) endianness or back.

This obviously won't help performance as the scene has still to be drawn at
the original resolution, but it's better than the draw-to-tile hack.

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!
