uhypsq calculates the hypotenuse using unsigned multiplication. This is
permissible since for arbitrary int32s a and b, the following holds in
two's complement arithmetic:
(int32_t)((uint32_t)a * b) == (int32_t)((int64_t)a * b)
("Signed and unsigned multiplication is the same on the bit level.")
This fixes various overflows where wall lengths for walls of length > 46340
are calculated, but does not rid us of other overflows in the same vein
(usually dot products between vectors where one point is a wall vertex and
the other a position in a sector).

EVENT_SOUND: triggered upon playback of any sound, this allows the "hard coded" sounds to be altered in a context-aware fashion instead of having to resort to clunky hacks like replacing them with a blank sound effect. RETURN var
iable is set to the sound effect # of the sound to be played, or -1 to cancel playback.
EVENT_CHECKTOUCHDAMAGE: triggered in P_CheckTouchDamage() whenever the player collides with anything. Value of RET
URN is set to the result provided by clipmove() and so can be decoded in the same way. Value of RETURN when the event is over can also be manipulated to control some of the hard coded damage effects.
EVENT_CHECKFLOORDAMAGE: triggered in P_CheckFloorDamage(), RETURN is simply the picnum of the floor of the sector t
he player is in. Can be used to cancel hard coded floor damage effects or to make other tiles exhibit the same eff

(I.e. also restore r2232 again.)
The first one is the palette restore logic in G_DisplayRest, the second
is CON setgamepalette, to which the "don't gltexinvalidateall()" bit is
added to mimic the first. Hightile invalidations aren't really useful for
anything other than reloading them after a video mode change, IMO.
These changes mean that
1) active full screen tints should (almost) always be kept with a basepal
change. The only exceptions to this are when tints really have to be
cleared, e.g. when changing the player view in co-op play.
2) there should be no performance issues with simultaneously changing
basepals while a tint is applied

This requires one tweak in drawrooms' umost/dmost setup to prevent oob access.
Specifically, a coordinate difference of 0 is allowed. In the classic renderer,
this would mean a one-pixel (real screen coords) height or width. In Polymost,
it would currently mean a one-pixel height and zero-pixel width, but this might
be subject to change.

The showview command transforms the 320-based screen bound coordinates to the real
screen bounds like xreal = (x*xdim)/320, which shows a bias towards zero: for
example, for a 1680 screen width, the maximum permissible value 319 is mapped to
round_to_zero((319*1680)/320) == 1674. (The rounding is implicit in the integer
division). This makes it impossible for a view to cover the whole screen with any
other resolution than 320x200. The new command transforms the bounds like
xreal = (x*(xdim-1))/319, which would map 319 to 1679 in the preceding example.

The major outside-visible change is that this fixes the sound cutoff bugs that
happened because newly-spawned sprites took the place of those whose sounds
had not yet finished playing.
Besides, there are these changes:

sprite freelist tail
- we need to store it in savegames and mapstates, so bump the savegame

Internally, the last argument to neartag is now a pointer to a function
int32_t (*blacklist_sprite_func)(int32_t i),
which is supposed to return 1 if sprite[i] should NOT be considered for hitting.
This is now used in the hard-coded neartag() calls in sector.c, but not in any
way in CON (there's neither a C blacklist function provided, nor is there a
possibility to define one in CON). There, all sprites with picnums >=1 and <=10
(i.e. the effectors) will be blacklisted. This remedies problems where such
sprites would get in the way of switches.
Note that a whitelist approach (only consider a predefined set, namely those
picnums which will be checked afterwards) has back-compatibility implications
since people may have used e.g. lotagged window sprites to cover a switch.
Also, the >=1 to <=10 range is [sic] (the static, not dynamic values are used),
since anyone redefining effector picnums is clearly out of their mind.

Since the original source code release of Duke3D, there was a potentially
dangerous hack where actor[].dispicnum was set to -4 to signal "this actor
should not have a floor shadow for this moment" (it doesn't really work,
if you ask me).
Now, use another bit of actor[].flags for that purpose because setting
any picnum members to negative values asks for trouble.

crashes.
Usually, after loading a game, some wall tiles are tweaked depending on whether
adult mode is enabled or not. If it's not, those wall picnums are replaced
with blank or broken screens. If it is, they are restored from the wall's
.extra member. Apparently though, Mapster32 leaves some .extra members
floating around even after deleting a TROR nextwall link (it's used as the
'lower wall index'). Because MAXWALLS is greater than MAXTILES, this may
produce out-of-bounds accesses and corrupt memory (besides setting wall
tilenums to nonsensical values) later in the game.
Other than that, the change only affects loading savegames created with adult
mode OFF. Kinky TV screenies simply won't be restored then.

size of 128 bytes. New code currently disabled and #ifdef'd for comparison.
This requires certain t_data[] entries ([1]: move ptr, [4]: action ptr and

breaking savegame and net packet compatibility (we could in theory try hard not
to, but it would be too much trouble).

This is useful for TCs like my add-ons, where for my pseudo-mutators I currently say "include EDUKE.CON", but I also have to juggle this terrible order of paths, so that I can have an EDUKE.CON file in my HRP which says "include GAME.CON" to allow the mainline game to actually run, but also allow DukePlus to load its EDUKE.CON file (since it uses that and not an -x switch), and also allow any custom EDUKE.CON files in the root to be used."

* Prototype of a mechanism to gray out certain portion of a map, making them inactive to various, but not all, editing operations. Highlighting a set of sectors and pressing Ctrl-R will make the Z bounds be [(least ceiling z), (greatest floor z)] of all selected ones, pressing Ctrl-R when no sectors are highlighted will reset them. Not sure if it's for production use at this stage...
* The 'align walls' feature [.] now has three independently toggleable behaviours: recurse nextwalls (toggled when Ctrl is pressed), iterate point2s (disabled when Shift is pressed), and also copy pixel width (toggled when Alt is pressed).
* Make shades clamp instead of overflowing in the editor
Fixes:
* crash when carrying out certain operations on walls with xrepeat 0
* the Pause key on linux. Also make demo recording start on Shift-ScrollLock because ScrollLock alone is too easily pressed when pausing
