GZDoom g4.3.0

PLEASE DO NOT DOWNLOAD. THIS RELEASE HAS A SERIOUS ISSUE!!!

*vid_scalemode 1 now only goes down to 640x400 at minimum, instead of 320x200
*added Esperanto menu option.
*Support for MIDI on Linux via alsa sequencer
*rewrote the ZMusic interface so that it is free of C++ constructs.
*the timidity safe_malloc functions may not throw exceptions.
*added pixel ratio detection to supersampling detection for forcing linear scalingthis should likely make it so if there's ever an instance where a viewport pixel is smaller than a screen pixel, the screen should go to linear scaling now
*set sane limits for vid_scale_custompixelaspect
*added the Dehacked extensions from Crispy/Doom Retro.
*made linear scaling more user controlled
*do config migration for vid_scale_custompixelaspect
*allow custom pixel ratio scaling
*SW renderer: Fix wrong blend tables used when dynamic lights hits translucent lines
*implement 'defcvars'
*Fixed a regression in DoTakeInventory. (the C++ code just ignored the null pointer, but ZScript can't do that)
*Add PSPF_PLAYERTRANSLATED flag (makes a PSprite layer translated to the user's color)
*Fixed: Invulnerability checking for rails was done before the various THRU actor flags instead of after, meaning actors could block shots regardless of those flags. This was never intended.
*Added STOPRAILS actor flag.
*export TMap<FString, FString> to ZScript
*let a sight check that gets lost return failure.
*fixed Harmony's end text's name.
*update window title with current level name
*removed symbols to fix zdoom.rc being modified after checkout
*reinstate 320x200 with the following caveat: it only functions outside of menus and console, and only when the dialogues and logs use the default font, the game will temporarily switch to 640x400 in these situations
*change IWAD startup dialog to allow selecting between OpenGL, Vulkan, and SoftPoly backends. (windows only)
*precache switch textures from ANIMATED lump
*upsample texture if width * height is less or equal to gl_texture_hqresize_maxinputsize squared
*added a few more texture coloring options to the shader.
*added minimal time profiling of texture precaching
*improved normalNx scaling performance by ~10%
*implement vid_scalemode = 6sets absolute minimum scaling to fill entire screenuseful for speeding up software rendering
*allow more than 8 sound channels per sound source. This requires a new function interface because the old one's combination of channel and flags in one variable cannot be changed anymore.
*renamed IsActorPlayingSomething to IsActorPlayingSound and made it clearscope.
*fixed VOC loader. Its 16 bit code did not work because it set the variable to -16 instead of 16.
*do not expect user input if stdin is redirected
*removed redundant call to S_StopAllChannels()
*More compat fixes for Swan Fox maps (#982)
*add line_horizon on HOM line in Sapphire.wad
*removed dead menu options
*Fixed the JIT's OP_VTBL check not checking if it's already at the start of the code.
*fixed typos in Doom lights definitions
*fixed wrong display of Hexen AC for SBARINFO
*added null check to the dialogue lines array so that it doesn't crash if the text is never word wrapped.
*fixed: AActor::Revive did not restore flags8.
*fixed monster teleportation on Ancient Aliens MAP23
*added ability to set custom alternative HUD
*add cvar 'cl_disableinvertedcolormap'changes the invulnerability… (#972)
*exported several Wads.GetLump...() methods to ZScript
*Compatibility fixes for Clavicula Nox
*cl_blockcheats added to 'nocheat' check
*changed secret message handling so that the debug output of the sector number is only printed to the console but not the centered message.
*new zscript function 'SetLineVertexes(line, v1, v2)'
*added generic level post-processing script class
*improved handling of return value mismatches
*set meaningful defaults on initialization of BaseStatusBar
*add Vulkan to the startup box in Windows
*fixed missing fullbright for Berserk
*fixed source lump assignment for multipatch textures
*mixins.
*fixed bad variable name for lump filter
*fixed: IfGame else branch was ignored in MENUDEF
*fixed: lump filters without any dot in the name did not work.
*implement ccmd 'togglehud' for taking screenshots
