157aa207e4 engine.c: clean up drawsprite()
The usual: declare locals more tightly, const-qualify them where it helps
readability, remove dead code...

14e97b2a57 Don't set spriteext[].tspr when creating tsprites from the engine.
Its only use is to have a actor -> tsprite mapping for the EVENT_ANIMATESPRITE
event and .tspr will be set before it is run.

cb20ad6e90 engine: in texel-hitscan wall-aligned sprites, consider engine-side animation.
Whether a sprite is considered for texel-hitscan is determined on the base
tile number, not the individual animated tile numbers.

"lastwall"s (i.e. the CCW-linked points) should get collected. This is
to signal the editor that their wall lengths should be displayed, too.

4a6ded3f98 engine: fix a possible crash with texel-hitscan.
Reproduced as follows (assuming all tiles have texel-hitscan for simplicity):
In E2L5, shoot the opening switch with the shotgun, aiming for the border.
The crash occurs because the *other*, depressed switch tile isn't yet loaded
when we index into its tile storage. Dereferencing 0+small number == BAD!

9dc1d212a7 Classic: fix drawing tilesizy=512 walls, use non-pow2 routines with pskies.
The former is really only a workaround. Walls/vertical sprites/pskies with
ysize 512 (and presumably greater, but this was not tested) are rendered
with one shade higher at the borders (1 pixel vlines) because of a certain
assumption in the ASM (see comments there). With very dark shades, the
palookup[] buffer is accessed oob. We simply allocate 256 bytes more at the
end for each.

The latter is only for CLASSIC_NONPOW2_YSIZE_WALLS builds, which is not enabled
yet. It seems to matter only for the uncommon case where the such pskies repeat
in the height. A 1680x1050 window fully covered with such a sky is then rendered
at about 60/85 the FPS for me (mostly due to not using the 4 pixel vline
routines), so it may be leaning a bit too much on the side of correctness.

A compilation switch DEBUG_TILESIZY_512 is introduced in engine.c for
demonstration purposes.

3ff46c02b2 Fix the warnings when building with C++, add MSVC C++ build support. This also changes the internal type of lotags, hitags and cstat type fields to uint16_t instead of int16_t to clean up some dubious behavior wherein the code was using a value of 32768 as a flag in these fields for certain types of things, like invisible sprites (using the value as if it was uint16_t) where it was elsewhere checking if the value was < 0 (using the value as if it was int16_t). This change may break a few specific effects if any part of the relevant code was missed when looking for areas that needed to be addressed.
I think there's also a fix for the CON precache system breakage in here (lost it in my local tree when I started getting the C++ build working in MSVC, sorry!)

fcf9beae6a Work-in-progress adjustment to the C code to compile under C++. It builds for me without errors using Win32 MinGW-GCC, but it still generates warning soup. No guarantees about MSVC or anything using SDL. Enable C++ by building with CPLUSPLUS=1. C remains the default and should compile with no change in setup.
Credit to Plagman for the idea and doing the work on the game side, which is included in this commit.

(Building as C++ will give us features with which we can make improvements and optimizations on the multiplayer code and Polymer.)

a5f479787f Remove built-in copy of nedmalloc and update nedmalloc.dll. Note that the built-in copy of nedmalloc hasn't been updated or enabled in a really long time as modern system allocators (Windows 7 and Linux 3.x at least) are no longer consistently beat by nedmalloc (but nor are they consistently faster). So, the dll remains for users of Windows XP because it may still improve performance there (while not likely degrading it on Vista/7).

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).

3e4357c6a4 Integer Overflow Offensive continued: first round of -ftrapv - cleanness.
That is, "clang -ftrapv" builds don't abort almost immediately after entering
a level.

There are various classes of overflow bugs, needing different handling:
 - Some texture mapping code was written with signed integer wrapping semantics
   in mind.  In some places, we're able to get away with unsigned casts.
 - sometimes, we really need a wider range, like when calculating distances or
   dot products
 - negating INT_MIN.  Here, we cast to int64_t temporarily.  Note that if the
   result is 32-bit wide, no 64-bit code may actually need to be generated.
 - shifting into a signed integer's sign bit.  We cast to uint32 here.
 - in hitscan(), at the "abyss crash prevention code" comment, it's clearly
   the other code that is better...

This is not merely done for pedantry, but rather makes it easier to track down
overflow bugs having a real impact on the game.

b30ac41147 Integer Overflow Offensive, First Act: rintersect, hitscan, neartag.
It's time to replace some int32s with 64-bit ints in core engine functions.
The problem is that for example, the dot product is taken between vectors that
may be the difference between two arbitrary points in a sector, so even if one
sticks to the "no blue walls" rule, that doesn't guarantee freedom from
overflows.

ebbb3e304d Tweak the conditions under which setbrightness() invalidates GL textures.
Previously, we checked whether the faded palette has changed (by way of CRC)
and invalidated the textures then unless the preserve flags were set.  This
however could lead to wrongly invalidating them under unfortunate circumstances,
e.g. basepal change from CON + tints at the same time before r2620 which
reverted r2232.

Now, only invalidate them if the corresponding preserve flags are clear AND
 * the base palette has really changed OR
 * the palette CRC changed and we were running on software gamma
The latter means that performance-killing invalidations may still happen on
GL platforms lacking HW gamma (for ATI, it's currently only disabled in 8-bit
fullscreen).

Also have a new global 'basepalreset' to fake a basepal change for
setbrightness(), currently used when changing renderers so that going from
Polymer to Polymost and back again will invalidate the Polymer textures
on the second change, potentially re-applying a basepal highpal. (Still
with me?)

34c0e85295 Allow the screen bounds difference in CON showview/-unbiased to be less than 2.
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.
