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).

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.

I find this cleaner for two reasons. First, lotags won't get in the way of
neartag(), so that doors and switches near constrained TROR walls can be
pushed. Second, this removes the information leak so that CON coders aren't
tempted to read that values directly before a proper API for that comes along.
When writing out a map in-game (e.g. with dndebug), restore the respective
members so that it can be loaded in the editor again.

If enabled, this makes the following arrays be allocated statically:
spriteext, spritesmooth, sector, wall, sprite, tsprite, while
necessarily disabling the clipshape feature (because it relies on
setting sector/wall to different malloc'd block temporarily).
To compile, pass DEBUGANYWAY=1 in addition to RELEASE=0 to 'make',

The cause was a combination of many factors. First, Polymer requires the
start-drawing position to be inside the sector to draw (deviations lead to
incorrect drawing). This was violated by the game, because it interpolated
the current and next tic position without updating the sectnum, leading to
inconsistencies especially when passing through narrow sectors. Polymer
worked around it by doing an updatesector() each frame, however this works
poorly for maps with overlapping geometry such as SoS or RoR.
The solution to this is to add a new engine function,
updatesector_onlynextwalls(), which searches the sectors (via nextsector)
in breadth-first fashion instead of from 0 to numsectors-1, like updatesector
does when it fails for the *immediate* nextwall neighbors.
Internally, the breadt-first search helpers are moved into the engine.

This makes savegames practically the same as the initial snapshot of a demo.
Saves are now named 'dukesavX.esv' (demos: 'edemoX.edm').
Additionally, many changes that couldn't/needn't be cleanly separated are added
with this commit:
- make spriteext_t have the same size across 32/64 bit platforms (actor_t partially)
- prevent saving/loading in MP games (it certainly didn't work and still doesn't)
- it's time we start using assertions! Define NDEBUG for releasse builds.

When having drawn N new points (and having one 'free') and pressing
ENTER, the N line segments between the new points are checked one by
one for intersection with every non-grayed-out wall and a wall vertex
is inserted at every intersecting point. This may be viewed as a
prerequisite for a 'cutter' style tool.

functionality, Polymost).
The new feature can be enabled/disabled with the 'r_tror_nomaskpass' cvar.
The basic idea is that when drawing lower or upper levels, a first pass
is performed that ignores all red walls for which the TROR nextwall link
'towards' the viewer arrives at a red wall. Thus, in the worst case, there
can be up to twice as many rendering passes now (when it is discovered that
the no-mask-pass isn't different that what would be drawn with the ordinary
one, the latter is skipped, since we've already drawn all needed geometry).
Hovever, this kind of multi-pass splitting is only suitable for simple scenes,
like the upper subway in the TROR test map. In particular, multiple islands
shouldn't 'see' each other.
Two issues are worth mentioning: first, care needs to be taken for translucent
ceilings or floors, since drawing them twice isn't the same as drawing them
once. This is done for classic, but not for Polymost. Second, sprites (which
are always drawn _after_ the geometry for a given pass) are still clipped to
the geometry of the ordinary pass, resulting in their disappearance from
certain angles.

which switches have been hidden in the original and user maps. One is to make
it face a wall, and another is to 'embed' it in e.g. the floor, like the
monitor with the burning fuse in E4L1. Both kinds show up when the switches
are rendered as models, revealing the secrets that the mapper sought to hide.
My proposal, implemented in this commit, is to apply a heuristic for such
switches at premap and make them invisible (set cstat bit 32768). The
conditions are re-checked during the game in case there is a switch coming
out of the floor, for example. A new spriteext bit is used for this feature.

The main feature is the addition of -mx and -mh command-line parameters to EDuke32 and Mapster32. These parameters include a con and def "module" respectively. This translates into essentially including the file from the bottom of the compiled script.
I fixed the classic buggy behavior of the BROKEHYDROPLANT and REACTOR2 sprites.
I also fixed a small, long-standing bug where FRAMEEFFECT1 blurs are not affected by sector floorpal. You can see one example of this by shrinking the Enforcer on the upper inside of the toppled building in E3L11: Freeway.

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."
