What changed in EDuke32, build by build

This code is neat, tidy, organized, and sensical!

Ugh, global variable hacks. Excuse me while I wash my hands.

Fixing movement when not loading a.m32.

This fixes an update issue: start EDuke32 without warping to a map in Polymost, change to classic, and change to Polymost again. The OSD background will be displaced.

Also, fix quote commands there.

If m32script gamevar "move_by_one" is nonzero, the some keys move the "player arrow" by increments of 1: - Without SHIFT: LEFT/RIGHT absolute x, DOWN/UP absolute y, A/Z absolute z. - With SHIFT: DOWN/UP (unbounded!) horiz, LEFT/RIGHT angle. This can be useful to debug renderer bugs that show a high sensitivity to the exact location ("are transient in space").

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.

That is, first check if the sprite is in the game world and then if it already has the desired sector or status number. This doesn't change anything in our codebase, since the return values of these functions are never examined.

The usual: declare locals more tightly, const-qualify them where it helps readability, remove dead code...

Also taking care that the USE_OPENGL=0 build builds.

Simplifying VM_FallSprite and VM_ResetPlayer2 used from Lunatic.

Meaning that only *ettsprite[THISACTOR] makes sense from CON. It did before too, because .tspr was set before each event run (and not before all runs), only that it was never nulled, which was kind of untidy.

Its only use is to have a actor -> tsprite mapping for the EVENT_ANIMATESPRITE event and .tspr will be set before it is run.

The m32script variable 'showrespawn_always' toggles whether the respawned picnum is shown unconditionally instead of only when aimed at (and locked onto the RESPAWN sprite) in 3D mode. Cool idea by Micky C. NOTE: sometimes doesn't work because of a bug in the m32script interpreter.

Use a new flag to mark hard-coded enemies, not SPRITE_BADGUY. This fixes an issue where in E1L4, a pigcop would appear in the area you have to crawl under shrunk. Thanks to LLCoolDave1 for pinpointing the range of relevant revisions.

Whether a sprite is considered for texel-hitscan is determined on the base tile number, not the individual animated tile numbers.

One use was in determining the ray vector for the mouse-aiming hitscan in the editor. Unfortunately, the change doesn't make it any less broken in Polymost, even if the two instances were out of sync.

If enabled, dragging wall vertices will correct the xrepeat after the mouse button is released, so that the pre-drag absolute stretching is restored.

- Run it twice, since the first one is wrong. - Warn when attempting to align based on a top-oriented wall. When the sequence of walls to align has "windows", only the bottom parts will be correct. - Make the modifiers actually useful: * Pressing SHIFT aligns at most one wall, remove the old CTRL modifier. * The rest is as before: ALT makes the walls have (approximately) equal texture stretching, ['] (quote) aligns the immediate TROR-nextwalls.

Also, factor out 2x dup'd code of insertsprite() into do_insertsprite() and add searchwall-displaying code into package/samples/a.m32.

Also, add another flag, signifying that from the editor, also the "lastwall"s (i.e. the CCW-linked points) should get collected. This is to signal the editor that their wall lengths should be displayed, too.

- Stop using memcache on some other failure paths, particularly when failing to read from the on-disk texcache. - Factor out cache reading code (3x). - Fix endianness issues affecting big-enadian systems (one introduced by r3382, one existing before). Comment each B_LITTLE32 with whether we're converting from native to on-disk (little) endianness or back.

When reaching wall limits, it is possible that only some circle points will be inserted and the result is left unfinished.

- fix error handing with recursing events - wallsofsect iterator, sector[]:contains() - more codegen; mangle function names - m32: compinside
