Most often, this had happened when casting comparison functions for qsort()
like these: "int yax_cmpbunches(const int16_t *b1, const int16_t *b2)"
to a function pointer type expecting "const void *". Alas, this is undefined
behavior: see
http://blog.frama-c.com/index.php?post/2013/08/24/Function-pointers-in-C
and posts linked from it.
At least two cases have not been fixed:
- The savegame system maintains pointers which are either to data or a function in
the generic "void *". This ought to be made into a union.
- Probably also:
#define OSD_ALIAS (int32_t (*)(const osdfuncparm_t*))0x1337

- Rename sky_t members: yscale -> horizfrac, bits -> lognumtiles.
- Add default sky (8 tiles, horizfrac=32768 (i.e. 1/2 the scene horiz), offsets
all zero) and CLOUDYOCEAN sky (8 tiles, horizfrac=65536, offsets all zero)
to multipsky[].
- Get rid of "psky_t g_psky", merely maintaining a g_pskyidx instead. Set it up
at map load time so as to keep the behavior of the legacy per-map psky:
the last sector index with a matching psky ceiling wins.
- In mapstate_t, save g_pskyidx too, not (former) pskybits and pskyoffs[].
- Make on-map-load global psky setup consistent for the game and editor by
factoring it out into common.c: G_SetupGlobalPsky().
- Remove a couple of useless initializations, add some static assertions.
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
multi-psky is found. This is only likely to affect the yscale/horizfrac of
non-multi-pskies when a global non-default multi-psky has been set up.
Bump BYTEVERSION again.

- Consolidate psky* arrays into a "typedef struct psky_t" "g_psky" and
"multipsky[]".
- Factor out getting parallaxed sky properties into getpsky().
- Condense initial multi-psky setup by memcpy'ing from multipsky[].
- New function: MultiPsky_TileToIdx().
- Add new define PSKYOFF_MAX and related consistency-checking assertions.
- Lower MAXPSKYTILES to 8 to reflect current usage (was 256).
- Game: make multi-pskies consider dynamically-remapped MOONSKY1, BIGORBIT1
and LA. (Not very useful as the editor will still only act for the static
values -- 80, 84 and 89, respectively.)
An attempt has been made to preserve behavior even in strange cases, so this
commit is unlikely to introduce regressions. Because of point 6, BYTEVERSION
had to be bumped.

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.

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.

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.

- 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...

Implemented using GL_LINEAR fog. The only source of difference (besides the
obvious indexed vs. true color) should now be the distance constant, which
still had to be determined experimentally. Polymer implements this mode in
its fog fragment program part.

It was caused by the definition of c_dfDIJoystick using literal 24 and 16 values in place of sizeof(DIDATAFORMAT) and sizeof(DIOBJECTDATAFORMAT), which include pointers. On 64-bit, the values end up being 32 and 24, causing a discrepancy in which DIERR_INVALIDPARAM was thrown.
