dea960d350 Fix loading maps in Mapster32, introduced in r3911.
Also, get rid of the strange filename[len]=255 hack in loadboard()
and make its file name arg const char* at last.

b2c5e2d807 Mapster32/Lunatic: ask when a <V10 map would be overwritten with a map-text one.
Also, clean up the saving/loading logic a bit:
- On load failure, display message with purple color.
- Take over the current file name ('boardfilename') only on success.
- Check SaveBoard() return values in various places.

db7f820404 engine: consider a point inside() a sector in all border cases (literally).
In other words, for a test rectangular sector, a sprite would be inside the
sector in on all 4 edges and all 4 corners. Previously, it would have been
the lower right portion only (*excluding* LL and UR corners), which led to
map editing issues.

9defc473c1 Classic rotatesprite: add assertion failing with DNF mod, comment another.
Among other things, rotatesprite doesn't cope well with large zoom values.
Two assertions are added that guard qinterpolatedown16short() calls: in
the failing case, they would write outside the destination arrays.
Another (existing) assertion is commented a little and like for the first,
instructions are given how to reproduce its failure.

520b608094 Engine: stricter map load time checking for sprites with oob sectnums.
Sprites are now considered to have out of bounds sector numbers if it is
< 0 or >= numsectors (not merely >= MAXSECTORS). If such a sprite is now
encountered during post-load, an attempt is made first to assign it a sector
number (using updatesector()). If that fails, the sprite is removed from the
map.  The background is that a dozen of maps do come with such sprites and
could previously corrupt the sprite list when loaded.

Specifically, in GL modes, and if the CHAINGUN is not replaced by a model,
 - draw the upper part twice: first, two screen pixels * weapon scale lower,
   then at the original position
 - reverse the previous order: draw the upper part first, then the lower part

This is much preferable to the previous engine-side hack, and to my eye,
it looks perfect now.

- Don't attempt to play an ANM file if it is empty (warn) or too short (error).
- If failing to read IVF file header or initializing VPX codec, don't play ANM.
- Return early from gltexapplyprops() if not in GL modes.

c5044b3ecd Add orientation bit 2048, enumerated as ROTATESPRITE_FULL16, which is a courtesy provided by the engine for the purpose of the game to internally force use of full 32-bit coordinates. With this bit set, all CON screen drawing commands can use rotatesprite16-like coordinates.
While the functionality was already internally in place for gametext as one of two hacks using ROTATESPRITE_MAX (the other still used by minitext_() to align with the statusbar) we must codify a bit in the engine for safe external use. (Otherwise, ROTATESPRITE_MAX could/would theoretically increase and leave modders high and dry.)

(Dev note: In G_DrawTXDigiNumZ(), ROTATESPRITE_MAX was used to bitshift the value used to calculate digit spacing for no reason I can ascertain other than to introduce rounding errors into the zoom/textscale calculations. It was never used anywhere, so I removed it.)

Bonus: The scaling code for digitalnumberz and gametextz has been modified so that the spacing is no longer affected by rounding errors. Try animating the zoom value and compare how the text used to jump but now does not.

40874820f3 Classic renderer: high-precision sprite drawing, preventing stray lines on top.
Face- and wall-aligned sprites are drawn using the wall routines in BUILD.
However, the per-x-screen-coordinate distance (swall[]) is calculated in a way
that potentially incurs great precision loss (for example 5 bits for
xdimen=1280, yxaspect=65536). This leads to the starting (top) vertical texture
coordinate possibly wrapping to large values, leaving an unsightly "stray line"
on top of the sprite from certain viewing angles/horiz values.

The approach to fix it has two parts: first, the distance is calculated using
float values, preventing the precision loss. Because this doesn't fully prevent
the unwanted lines, the texture coords are clamped to the mininum and maximum
(0 and UINT32_MAX respectively) when calculating them for sprites.

Note that stray lines may still appear at the *bottom* of sprites under certain
circumstances, for example when viewing at a y-flipped sprite from above.
These should be less noticable in real-world usage though.

The feature is guarded by a macro HIGH_PRECISION_SPRITE in case using floating
point or 64-bit integers is undesirable/impossible on some platforms.
