Available in the game and editor. Provide test/shadexfog.lua, containing a
function to creating a set of 32 shade tables corresponding to different shades
of the same fog palookup table, together with some tests and convenience
functions.
Also,
- Add gv.LUNATIC_CLIENT{,_EDUKE32,_MAPSTER32}
- Add LUNATIC_FIRST_TIME in the global env for the game
- defs_m32.lua: add reload() convenience function
- Failed attempt at recreating the base shade table. It is NOT a linear ramp
of the base palette colors to (0,0,0). That is, it's not created by
build/util/transpal.exe!

It is unacceptable that yvel is on one hand modifiable without restriction from
scripting, but can be used as an array index without prior bound check in the C
code. Because that member has an overloaded meaning and is also used for
innocuous purposes such as the green color intensity of an SE light, it's
infeasible to restrict access from scripting. Consequently, we must add bound
checks on the C side. This is the first part of the effort to make .yvel safe,
adding two functions P_Get() and P_GetP(). There are a couple of other uses as
some kind of index.

Variables at global scope which share a name tend to actually be the same variable. Not good when you pass such a variable to function that immediately returns if the passed parameter (the variable) equals said variable (itself).

Permitting to enable various debugging options. See "eduke32 -debughelp"

The check is dead because it is made after the fact (oob access), but the
cheat string matching logic below actually assures that
cheatbuflen < sizeof(cheatbuf) at all times.
Exposed using the Stack tool from http://css.csail.mit.edu/stack/ .
Also, in gamedef.c's definecheat handling, print the string length (19), not
the buffer length (20) if the cheat was truncated.

Clang's UBSan reports this as undefined behavior. I think that the reason
is as follows: C99 6.5.3.2#1 (Constraints) says:
The operand of the unary & operator shall be either a function designator, the
result of a [] or unary * operator, or an lvalue that designates an object that
is not a bit-field and is not declared with the register storage-class specifier.
But in case of an expression like "&array[-1]", the operand ("array[-1]") does
not designate a valid object.
Moral: check first -- assure that an expression is valid for a particular
operation before carrying it out. Keep in mind that otherwise, the compiler
is absolutely free to optimize out the *check*.

- 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.

It was only ever used as upper bound to the time that a visibility change
decays, but since it does that in an exponential fashion, there's really
no point.

Now, if p->visibility differs from the constant visibility, the former converges
toward the latter by three-quartering the difference each second totalclock
increment (1/60th second).
Negative player visibilities are not handled consistently throughout the
different renderers, so make it look the same as 0 (can view to infinity).

The commit revises the definition of qstrdim when TEXT_[XY]OFFSETZERO are used. With these flags, the offsets the user specifies are now the only dimensions the function cares about in terms of tile placement, so depending on the difference between the offset(s) and the size of the final tile, it may be slightly more or less than the dimensions actually displayed on the screen because tile size is never taken into account. (For example, if your font is nominally 9x7 like the Duke bluefont and you use a TEXT_XOFFSETZERO of 5 with a string five characters long, the total x dimension will be 25 even though the last character will overhang that amount by four pixels. If you use a TEXT_XOFFSETZERO of 12 with the same string, the total x width will be 60 even though there will be three pixels of empty space on the right edge.) This change was made because assigning text an arbitrary constant width in general implies an intent to keep character positions constant even with a variable width font, but returning the visible span of pixels on the screen that the tiles cover would have caused the string to move when alignment options other than the top-left were used. In other words, you can now safely use TEXT_[XY]OFFSETZERO with the alignment options and the text won't jiggle.
Also, with TEXT_GAMETEXTNUMHACK, numerals are now effectively TEXT_XOFFSETZERO text that respect the above paragraph, so number count displays can look nice with alignment options too.
Having to modify the extent/offset code makes me realize that I'm not quite happy with its structure because it gets tangled juggling different concepts like character width, X offset, and spacing, and how they relate when the line wraps or in terms of the final size. Fortunately, it produces correct results as far as I know, and it's not necessarily ugly, just hard to understand. Handle with care.
