they escape to somewhere they might be used as such.

negative value. Also, fix a _sound call in _addphealth in control.lua.

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.

There's only one RETURN value on the C side (g_RETURN), which is also referenced
from Lua. Upon entering an event, its value takes on the per-event default one,
and its value when the event code finishes is passed back to the game.

Previously, actor[].shootzvel (implementation detail, not available to CON)
was checked, and if it was !=0, that was the overridden velocity. The value
0 meant "hardcoded, projectile-dependent velocity". But that neccesiated a
hack where if zvel 0 was passed and really meant, it needed to be set to
1 instead. Now we have A_ShootWithZvel() taking an additional last argument
plus a macro SHOOT_HARDCODED_ZVEL permissible for that argument.

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.

On the engine side (functions starting with L_), there are now the basic

The game and editor can add to that by e.g. loading whatever they please

The Lua scripts still reside in source/lunatic, even for the common ones.
This is because they will be embedded into the binaries as bytecode or
