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.

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

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.

- 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.

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!

- Rewrite the "clear background" routine in a no-brainer way instead of
juggling around with rotatesprite(). Make it common to game+editor.
Expose glRectd to glbuild.
- Don't stop OSD text line drawing when encountering a non-printable char.
Instead, treat it as space.
- In OSD_SetTextMode(), don't use swaplong (which really swaps 32-bit ints)
to swap pointers. Write an analogous "swapptr" instead.
- When changing from/to OSD, don't inject a pause key. This *might* have been
the cause of the reported pausing problems.
- clean up the code...
(Yes, this commit throws together too much stuff. I suck sometimes. :P)

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.

- If aiming at a swapped bottom wall, display "Wall <wallnum> -> <otherwallnum>"
- highlight pic, shade, pal, cstat in yellow then
- in printext256, accept at most 3 digits for the color format string (e.g. ^123)
