What changed in EDuke32, build by build

Fix missing/invalid palswaps and shades in automap with Polymost

Add EVENT_DISPLAYROOMSCAMERATILE

Make the gamma slider move in increments of 0.05 instead of 0.1

add wall point delete hotkey. Press shift+delete or the d key in 2d mode to delete a wall point without dragging it.

Add mutex to protect against S_Callback() being called from more than one thread at the same time

I honestly can't remember why I wrote this like this, but it's problematic so I'm changing it.

Make the time period between averaging the min and max values shown with r_showfps 2+ user configurable with r_showfpsperiod

Create new MV_CleanupVoice() function to handle most of what was in MV_StopVoice() plus the MV_CallBackFunc() functionality

Slightly revise multivoc locking logic

Fix an infinite loop in S_StopEnvSound() that could occur if the audio thread happened to finish playing a voice in between checking if g_sounds[].voices[].id > FX_Ok and calling FX_StopSound(), exacerbated by improper std::atomic usage

Re-add something I didn't intend to remove with r7297

Remove 'none' as an option for the frame limiter in the menu and fix a bug with the slider for the offset

Re-enable -fno-strict-aliasing because apparently many versions of GCC across many platforms are still producing warning spew without it

MSVC build fix

Fix NETCODE_DISABLED builds. We should probably rename Net_GetPackets() to something else, because it does other required things.

Fix loading screen tile

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

Fix issue where the player's pistol isn't removed when they spawn on HURTRAIL/FLOORSLIME/FLOORPLASMA

macOS build fix. DONT_BUILD.

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

Expand the list of options available for the framerate limiter, and add a separate option that controls an offset added to the limiter. This should allow the menu to cover all of the important use cases involving G-SYNC, FreeSync, and "Fast Sync".

Fix net.cpp line endings

Slight cleanup to MV_GetVorbisCommentLoops(). The biggest change here is swapping calls to atol to our Batol macro, which is actually backed by strtol instead of atol.

Hendricks and I discussed "auto *" and we've come to the conclusion that it's bad form, so this corrects that.

Reduce vorbis read block size from 32k to MV_MIXBUFFERSIZE. Despite requiring more calls into libvorbis, this should be faster on slower CPUs in cases where more copies of the same .ogg sound are attempting to be played at once than are allowed, e.g large explosion scenes in Ion Maiden.

I don't see a reason for these operations to be separated

Fix function that some sadist formatted with 3 spaces

- 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.

macOS build fix

Fix oversight with wall texture rotation on tile 0

Fix issue with a couple symbols from cmdline.h sometimes picking up different linkage due to accidental double definition in game.h

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

Add unsigned access to actor .htmovflag through actor .htumovflag

Misc CON fixups

Further clean up C_SetScriptSize(). This also fixes a bug in the function where when expanding the buffer size, most of the extra space was left uninitialized due to bad parameters passed to memset().

Clean up A_InsertSprite() and the beginning of A_Spawn()

Sorting and formatting for [names|sound]dyn.[cpp|h]

Cleanup includes

SDL 2.0.9

Use references in G_UpdatePlayerFromMenu() and G_BackToMenu() for readability

This does nothing but fix indentation of a single block of code

Remove some effectively dead code that handled loading from duke3d.cfg if eduke32.cfg was not found. This has been useless for about a decade.

Move the LZW compression functions out of cache1d.cpp into their own object, klzw.cpp.

Refresh BUILDLIC copyright headers

ifdef out all use of libc's FILE in libxmp-lite

Fix a big fail in my implementation of CON_DIVR and CON_DIVRU.

Drop C++ standard used in Visual Studio builds from C++17 to C++14, to be more consistent with our GNU makefile.

Move CONTROL_ProcessBinds() call to P_GetInput()

Fix usages of tab characters that slipped into menus.h at some point, and fix declaration of function Menu_Change() to match its definition

Very (very) slightly less terrible G_CheckPlayerColor() function.

Additional const and constexpr usage in compat.h and pragmas
