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.

There are instances where oob picnums may propagate to that function, so
protect it. The digitanumber[z] bound check is actually made more permissive,
but could also just as well be removed now.

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:
- remove deletesprite{sect,stat}
- we have a new engine variable 'tailspritefree' that keeps track of the
sprite freelist tail
- we need to store it in savegames and mapstates, so bump the savegame
minor version

This might now be even more confusing for users reading both the source
and CON code (where the access is necessarily still via '.clipping'),
but at least reading the source now makes sense :P

This is so that in the event of a crash, no CON dump will be printed if no
(actor or loadactor) CON code was actually executing at the time of the
crash, confusing the users. Note: doesn't apply for event code.

We've been running with same-sized actor_t for a while without problems now.
In the unlikely event (famous last words) that an issue should pop up later,
this revision should be consulted for the differences between the two versions.

This was causing oob sector accesses with code like this:
getwall[hitwall].nextsector temp
ifvarvare sector[temp].floorz sector[temp].ceilingz setvar tempb 1
(from DT's HYPERCORE).
Also validate quote indices passed to CON's quote and userquote commands at
runtime.

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.

32- and 64-bit platforms. Also, make struct type actor_t also have a common
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
[5]: ai ptr with actors) to be converted to script offsets instead of pointers,
breaking savegame and net packet compatibility (we could in theory try hard not
to, but it would be too much trouble).

Actors are always moved such that _they_ clip against blocking sprites, even
if their blocking bit is clear. Setting the new bit make them not clip against
anything. The promary use of this is for decorative moving sprites that are
spawned in masses, such as rain or snow.

setactorsoundpitch <actor#> <sound#> <pitchoffset>
which can be used to change the pitch of a playing sound.
The pitch offset has the same meaning as the definesound pitch range endpoints,
i.e. the units are 1/100th of a seminote. Note that just like the random pitch
offset, increasing the pitch makes the sound duration shorter (and vice versa).

of fetching the ceiling or floor height of the neighbor sector), but TROR isn't

"The most noticeable change is the addition of the "includedefault" CON and DEF command, which will attempt to include eduke.con (or nam.con, or ww2gi.con), then game.con, or duke3d.def, or nam.def, or ww2gi.def. 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."

* support for free mixing of multi- and single-tile parallaxed skies in classic
* make visibility independent of yxaspect and viewingrange in OpenGL modes
-- editor:
* when dragging walls, restore pixel width after that (only for the left and right walls of pointhighlight, and its nextwalls, if any)
* pasting on walls and auto-aligning them now carries over a few more fields
-- fixes:
* visibility in OpenGL modes wasn't incremented gradually (regression due to making 'clamp' an inline function instead of a macro)
* memory corruption due to calling qlz_compress with less than the recommended surplus storage of 400 bytes
* decorative sprites in the mirror showing non-flipped
* make the subway SE message (much) more helpful by showing which sector the game considers to be the track sector

* Polymer light access to m32script (light[<lightidx>].<field>). As an application, provide a state 'insertlights' that takes the currently active lights and puts them into the map as SEs (e.g. for maphack recovery).
* 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
