I didn't produce a case when this could actually have happened, but
reading the code, in the case of variable 'j' it seems possible with
an empty map.

-2d mode sprite colors are now automatically generated from the sprite's 8-bit tile.
-Zooming in and out has been smoothed out.
-The 2d mode crosshair cursor is now 1px thick instead of 2.
-The left mouse button can now be used to select multiple wall points and sprites in 2d mode.
-Ctrl-x now skips corrupt maps instead of going into an infinite loop. ;)
-'-L function in 3d mode works again.
-Sprites with a clipdist that has been changed from the default value of 32 will display a circular approximation of the distance in 2d mode. Note that the real clipping distance is actually closer to a square, but a circle looks much less confusing/stupid alongside the display of floor sprites.
-2d mode status bar has been made a few shades lighter.

This commit also implements a much more useful automatic grid sizing feature and smooths out zooming in and out of the map.

I have commented out the versions of these functions that perform bitmasks and shifts and replaced them with versions that cast to and from integral types, pending performance and compatibility research across platforms.

Examples: (assuming stock Duke palswaps)
copytile 10000 { tile 0 } // tile #10000 is now the same as #0
copytile 10001 { tile 1 pal 8 } // tile #10001 is now #1 with a full-green tint
copytile 0 { pal 1 pal 23 } // tile #0 now has a full-yellow tint

The latter means that running perpendicular thin sector is handled better

This fixes engine-side sprite animation in the following scenario: CON code
wants to draw a scene from EVENT_DISPLAYREST, but since it covers the whole
screen, disables the drawing of the 3D scene beforehand (RETURN set to 1 from
EVENT_DISPLAYROOMS). DONT_BUILD.

- In drawvox(), make view-relative x and y high-precision on desktops. To a
large extent (but not completely), this fixes "stray" fake floor shadow
sprites for voxels.
- In the mouse picking code for voxels, fix a possible integer overflow.
A new engine.c-private function mulscale_triple30() is added.

In setview(), we now assert windowx2 < xdim. The only calling places where its
non-violation is non-trivial to ascertain are (1) showview from CON and
(2) draw-to-tile for look-sideways in game.c. AFAICS case 1 should be fine.
Case 2 is adapted; see comments there.

Also for polymost_scansector(). These were likely of little consequence
because collection in scansector() is the exception than the rule (see
added comments), and because the redundant drawwalls() would find the
x range done the second and following times.
Also, add a bound check for sectorborder[] (the limit was probably rarely
hit in practice, but the check is mandatory nontheless) and add functions
printscans() and printbunches() in the DEBUGGINGAIDS=2 build.

There were various issues with that code.
- It does not seem to be very meaningful to do so.
- It was carried out on the same range as the sprites sorted by z coordinate
(those with equal x/y) just a few lines away, effectively overriding it.
The former is very meaningful, though.
- It led to inconsistencies between editor and game, see

Previously, the C function clipmove() returned negative values when hit a
wall (32768+wallnum) or sprite (49152+spritenum) because internally,
these values were encoded into a *signed* 16-bit integer. This made no
difference to C code using it, since it always proceeded by bit checks,
but was inconsistent with documentation on CON 'clipmove' on the wiki.
The following commands are affected too, since they use the value returned
by clipmove(): 'clipmovenoslide', 'movesprite'. Also, the value of
actor[].movflag ('htmovflag' from CON).
Also, fix 'clipmove*' in LunaCON and add lunatic/test/checknearwall.con
as an example of how to implement a being-close-to-a-wall checker as
requested in

Now passed as last arg 'noFloorPal' to makepalookup(). Used as follows:
- from loadlookups(): *false*, i.e. do take over floor pal.
- from generatefogpals() [default fog pals] and fillemptylookups(): *true*,
i.e. don't take over floor pal
- from DEF 'fogpal': true
- from DEF 'makepalookup': take over flag from pal from which we are remapping,
or set to true if remapping from pal 0
