This makes sure that the engine arrays have sufficient space allocated for usage
in Mapster32's 2D mode, for example from drawmapview().

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

They classify former uses of int64_t into two classes:

The extended PALETTE.DAT format can now carry a trailing byte, called
'lognumalphatables'. If it is present, the engine assumes that alpha blending
tables are loaded at blend indices 1 to 1<<lognumalphatables and handles
rotatesprite's alpha and spriteext[].alpha accordingly.
The ability to save this new byte is added to engine.lua:savePaletteDat()
and the corresponding convenience functions in shadexfog.lua.
Examples test/screentext.con and test/sprite_access.con are updated for
demonstration purposes.

The overall situation is thus as follows:
- in C and from Lua, that member is called 'fogpal'
- In CON (both C-CON and LunaCON), it's 'fogpal' with 'alignto' being an alias;
'filler' wasn't available before, either.
- In m32script, it's 'fogpal' or 'alignto' ('filler' is not available any more)

As opposed to the previous way, where the first fog pals was <numlookups>+1,
where <numlookups> is the first byte value of LOOKUP.DAT. This allows to
pack e.g. lookups [1 .. 25] and [30 .. <lastpal>] into LOOKUP.DAT and have fog
pals be generated at pals [26 .. 29] (i.e. the additional lookups don't
shift the fog pals, making user maps depending on these numbers not look as
intended.)
