With this mode, the near distance of the linear fog is always 0, unlike being
negative with r_usenewshading 2.

This "simply" requires an appropriate factor in the projection matrix.
Also, get rid of a special-case factor for >=1.6 aspects (making HUD models
wider then, I think).

Variables at global scope which share a name tend to actually be the same variable. Not good when you pass such a variable to function that immediately returns if the passed parameter (the variable) equals said variable (itself).

- Use the proper tile sequence when multiple pskies are present in a map.
However, there's still only *one* psky chosen at map load time.
- Handle three horizfrac cases:
* 0, psky always at same level wrt screen
* 65536, psky horiz follows camera horiz (e.g. E4L9)
* otherwise, fall back to default hard-coded parallax implemented as an
angle fraction

- Rename sky_t members: yscale -> horizfrac, bits -> lognumtiles.
- Add default sky (8 tiles, horizfrac=32768 (i.e. 1/2 the scene horiz), offsets
all zero) and CLOUDYOCEAN sky (8 tiles, horizfrac=65536, offsets all zero)
to multipsky[].
- Get rid of "psky_t g_psky", merely maintaining a g_pskyidx instead. Set it up
at map load time so as to keep the behavior of the legacy per-map psky:
the last sector index with a matching psky ceiling wins.
- In mapstate_t, save g_pskyidx too, not (former) pskybits and pskyoffs[].
- Make on-map-load global psky setup consistent for the game and editor by
factoring it out into common.c: G_SetupGlobalPsky().
- Remove a couple of useless initializations, add some static assertions.
This commit is more likely to introduce subtle differences in behavior.
Specifically, getpsky() now always returns the default sky properties instead of
the global sky ones (but with all-zero offsets) when no match for a suiting
multi-psky is found. This is only likely to affect the yscale/horizfrac of
non-multi-pskies when a global non-default multi-psky has been set up.
Bump BYTEVERSION again.

- Consolidate psky* arrays into a "typedef struct psky_t" "g_psky" and
"multipsky[]".
- Factor out getting parallaxed sky properties into getpsky().
- Condense initial multi-psky setup by memcpy'ing from multipsky[].
- New function: MultiPsky_TileToIdx().
- Add new define PSKYOFF_MAX and related consistency-checking assertions.
- Lower MAXPSKYTILES to 8 to reflect current usage (was 256).
- Game: make multi-pskies consider dynamically-remapped MOONSKY1, BIGORBIT1
and LA. (Not very useful as the editor will still only act for the static
values -- 80, 84 and 89, respectively.)
An attempt has been made to preserve behavior even in strange cases, so this
commit is unlikely to introduce regressions. Because of point 6, BYTEVERSION
had to be bumped.

That is, for shade of objects, use shade tables. For visibility, use GL fog.
Mixing these two does not produce satisfactory results in areas where both
shade and visibility darkening are high, such as around the E1L1 restroom.

The visibility calculation relies on the distance, which might not be entirely
accurate in rotatesprite, so maybe it'll be too dark in some cases.

- Return early from drawsprite_classic() if tspr->owner if oob.
Commonize that check between renderers into bad_tspr().
- Make the BIT() macro a left-shift of the *unsigned* number 1,
preventing expansion to (1<<31).

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.
