Cosa è cambiato in EDuke32, build per build

Fix issue where the option to enable or disable Polymer wasn't being saved properly

Revert "engine.cpp/.h: clean up & fix lintersect(). Additionally, add support for finding intersections of collinear line segments."

Fix issue with editor not allowing wall and floor aligned sprites to be resized in 2d mode without textured view mode enabled

This should fix the too many sprites spawned issue in single player

Change A_AddToDeleteQueue() to call A_DeleteSprite() on sprites it removes from the queue directly, as sprites with statnums other than STAT_ACTOR and STAT_MISC are not deleted automatically when their xrepeat is 0. This fixes using CON_INSERTSPRITEQ with sprites of statnums other than STAT_ACTOR and STAT_MISC.

- Packet code implementation (merge from private c/s repo), world updates are now synced through snapshots. See tag SVN_SyncPoint_Dec2018 on master of the other repo.

Fix oversight with wall texture rotation on tile 0

CON syntax extension: the empty "[]" shortcut for accessing a struct at index THISACTOR can now be omitted.

WIP wall texture rotation bit

stop playing sounds when entering the tile selector in 3d mode

Fix Polymer checkbox not showing up in the startup window in Visual Studio builds

Direct struct access for tsprite, and break special gamevar access out of Gv_GetVar() and into a separate function like it already was with Gv_GetVarX()

This is supposed to fix some errors with HIGH_PRECISION_SPRITE reported by a static analyzer, wherein 32-bit values were shifted and truncated as 32-bit before being widened to a 64-bit type, which didn't seem like the intended behavior. This is the commit to look at if anything is suddenly fucked up in the classic software renderer.

Rename the implementation of _lrotl() found at the top of kplib.cpp to klrotl() and use it unconditionally on platforms other than Win32 (it's only used in .bmp rendering).

Add CSTAT_SPRITE_ALIGNMENT_MASK. It's identical to CSTAT_SPRITE_ALIGNMENT_SLAB, but should be used in cases where you're checking either CSTAT_SPRITE_ALIGNMENT_WALL or CSTAT_SPRITE_ALIGNMENT_FLOOR rather than checking for a slab (voxel).

Update engine headers so that argument names in function declarations match the actual function definitions. This also removes const from function declarations in cases when it isn't meaningful.

Same sort of thing as the previous commits, but for the engine. Forward declaration cleanup and constification.

engine.cpp: fix crash when calling `setrendermode 3` where PolymostProcessVoxels would be called before Polymost is initialized.

polymost.cpp: temporarily disable experimental r_enablepolymost2 cvar

polymost.h: fix order of parameters to match polymost.cpp

polymost.cpp: fix lockup bug that would occur with polymost_waitForSubBuffer() when glClientWaitSync consistently returned GL_WAIT_FAILED on certain hardware/drivers.

Further revise a couple of null pointer checks in Polymost

Fix potential OOB spriteext[] access when checking SPREXT_NOTMD to determine whether or not to render a sprite's model, if available

Tweak osdfunc_setrendermode() to report whether the classic renderer is the C or ASM version

Fix overcomputation in the classic renderer due to a bug caused by a previous optimization attempt

Fix issue in the C version of the classic renderer where someone had attempted to negate a bool

Fix potential null pointer dereferences when rendering a model with no animations (?)

Apply the same autoaim Z position offsetting logic used on GREENSLIME and ROTATEGUN to any sprite with CSTAT_SPRITE_YCENTER set

Remove redundant code from Polymost fog

polymost.cpp/glsurface.cpp: Don't print shader compile status to the console on success.

Create P_GetOverheadPal() and restore the DOS definition of it.

Clean up variables in overhead map player sprite draw code.

Support software renderer upscaling engine-side in sdlayer and sdlayer12 with various scaling factors (beyond just pixel doubling).

sdlayer.cpp: Don't destroy window resouces if switching between software rendering on glsurface and Polymost/Polymer

polymost.cpp: make c_wrapThreshold consistent between POLYMOST1_BASIC_FRAGMENT_SHADER_CODE and POLYMOST1_EXTENDED_FRAGMENT_SHADER_CODE

polymost.cpp: fix rendering for indexed colour textures to match original behaviour when !r_usetileshades or globalflags & GLOBAL_NO_GL_TILESHADES

sdlayer.cpp: fix software renderer crash affecting Mapster32 due to improper handling of lockcount in videoBeginDrawing()/videoEndDrawing() when using glsurface
