Cosa è cambiato in EDuke32, build per build

Restructure and expand some ART loading functionality in the engine.

polymost.c: fix display of floor-aligned sprites ornameted to the ceiling.

polymost.c: split three overlong lines into three each.

Double the size of clouds[] (holding sectors with CLOUDYSKIES ceilings).

actors.c: fix 3 incorrect '/' -> tabledivide32_noinline rewrites in r4658.

Polymost parallax sky fix.

Make all the hictinting_apply blocks consistent. This should fix certain tints types being applied incorrectly in Polymer and the global tints (underwater and nightvision) not being applied to tints and models with certain flags.

Correct the HICTINT_GRAYSCALE calculation for hightile.

Complete the necessary infrastructure so that more than one precomputed tint on a hightile texture will display.

Eliminate a check that a model's sector's floorpal is nonzero before applying a tint.

Account for HICTINT_APPLYOVERALTPAL and HICTINT_USEONART.

Implement "renamefile" during game-side def parsing (normally for "loadgrp" et al.) in addition to engine-side def parsing.

Mapster32/C++ build/non-Lua: probably fix a crash in showsectordata().

polymost.c: fix an out-of-bounds access in polymost_dorotatesprite().

Add token "forcefilter" to textures, skyboxes, and model skins. It forces the use of GL filtering for the resource in question.

Engine memory reductions/optimizations:

Large batch of Polymost changes, including:

Polymer tsectortype usage. DONT_BUILD.

Minor stylistic changes, fix FPS counter and other 2D drawing in Polymer.

Further gamevar changes/optimizations. This also fixes a bug Fox reported with the "shortcut" access to structure members that's tacked on to GetVar, where if the value of the index you're trying to access happened to equal the ID of the current sprite, it would act as if the variable passed was THISACTOR.

Add "globalflags" def token. Flag 1 is a kill switch for the tileshades and artmapping features. Flag 2 is kill switch for the GL fullbright rendering pass.

Change HICTINT_USEONART so that it applies tints to pal 0 of 8-bit tiles instead of their palswapped selves. Add HICTINT_APPLYOVERPALSWAP which applies tints to palswapped 8-bit tiles. Add HICTINT_APPLYOVERALTPAL, which applies tints to alt-pals of hightile textures.

engine.c: style-cleanup getzrange(). DONT_BUILD.

Classic/Polymost: factor out update of starting sectnum, use updatesectorbreadth().

actors.c: make Enforcers and Troopers avoid ST1 sectors as in Duke3D.

Stick update of 'totalclocklock' at beginning of G_DrawRooms() instead of drawrooms().

in 'for i drawnsprites' handling, back up and restore sprite MAXSPRITES-1.

style-cleanup check_spritelist_consistency() and VM_Execute(): 'for'.

Under conditions of CLASSIC_Z_DIFF_64 (r4960), make some drawvox() vars 64-bit.

Fix Mapster32 mouse cursor in GL

Fix Polymer when switching from Polymost

Nocompress and nodownsize for skyboxes

Polymost changes to better support running under GL ES. Still need to investigate GL_LINES and GL_QUADS... neither work under either GL -> GL ES wrapper we've tried, so we must be doing something wrong.

Minor engine cleanup

Rename "Polymost.f" string back to "Polymost" because it only confused users.

in build.c, prevent oob of wall[] if joining non-adjacent sectors.

Remove some conditional disabling of spriteext features when !defined USE_OPENGL.
