Cosa è cambiato in EDuke32, build per build

Also move a 'int16_t editstatus' declaration from polymost.c to engine_priv.h.

Getting the texture handles without requiring invalidation means we can handle ART-animating tilenums without impacting performance too much.

Polymer has a hack that snaps horiz values of spotlights between 90 and 110 to 90 and 110 to avoid triggering aliasing artifacts with perfectly horizontal spotlights. Propagate that change all the way to the spotlight SE sprite so that the code won't think that the horiz is always different from the light and mark it invalid each frame.

This won't actually do anything until the a debug bit is added when creating the context, but that requires support for GLX_create_context which SDL doesn't support. I'll add support for WGL_create_context to winlayer in a bit as a stopgap. Also updates our local copy of glext.h with a fresh one from the Khronos registry.

We need to Y-invert the projection texcoords when sampling from the lightmap.

Sprites would stick with their old material on global palette change. This goes through all prsprites and clobbers their CRCs so that an alternate skin / tint / highpal can be applied accordingly.

The winding order of faces is different if only flipping about X or Y, and we were unconditionally culling CW faces.

the nextwall pointers correctly; Add some 'asksave=1' and 'make old-nextwalls invalid'.

most problems where sprites appear to be drawn through walls.

First, if we're in Polymer, don't precache tinted tiles that have a highpal for that certain pal. Second, don't precache tiles for palnum 251 (the last non-reserved one, which is used as a crosshair pal). Assuming that there are no other tints, this cuts the initial precache time and cache size on disk in half.

of the picnums of all sprites, omit the newly inserted sprite itself!

exclude grayed out walls.

- when pasting to walls or maskwalls, the following user bits are kept now: 4 (top/bottom alignment [O]) 1+64 (blocking, hitscan) 8+256 (x/y-flip) - print '(one-sided)' when pressing Shift + ([B] or [H]) on a wall

Keep track of which side is getting culled, swap around mirrors, swap around model drawing.

is picked" but still not perfect. In particular, sometimes a wrong wall is selected, and sprites don't get picked through portals. As a rule of thumb, don't be too far away from the objects you're modifying in 3D mode.

the additional rendering pass - Remove r_preview_mouseaim cvar from the game, since it's only for Mapster - sdlmusic.c: (Failed) attempt to fix a call of waitpid() with a non-existent process ID in the external MIDI playing code. I think there's a race there...

functionality, Polymost). The new feature can be enabled/disabled with the 'r_tror_nomaskpass' cvar. The basic idea is that when drawing lower or upper levels, a first pass is performed that ignores all red walls for which the TROR nextwall link 'towards' the viewer arrives at a red wall. Thus, in the worst case, there can be up to twice as many rendering passes now (when it is discovered that the no-mask-pass isn't different that what would be drawn with the ordinary one, the latter is skipped, since we've already drawn all needed geometry). Hovever, this kind of multi-pass splitting is only suitable for simple scenes, like the upper subway in the TROR test map. In particular, multiple islands shouldn't 'see' each other. Two issues are worth mentioning: first, care needs to be taken for translucent ceilings or floors, since drawing them twice isn't the same as drawing them once. This is done for classic, but not for Polymost. Second, sprites (which are always drawn _after_ the geometry for a given pass) are still clipped to the geometry of the ordinary pass, resulting in their disappearance from certain angles. -- Additionaly, a change made it into this commit that fixes redundant collection of sprites in TROR:classic/Polymost.
