Cosa è cambiato in EDuke32, build per build

MSVC build fix

Limit classic upscaling to 2x and 4x until issues with rotatesprite can be ironed out

CON_SWITCH maintenance

EDUKE32_STANDALONE stuff

Change sv prefix applied to savegame control cvars to cl for client (sv is reserved for server vars in multiplayer)

menus.cpp: Don't show texture filtering, anisotropy, or palette emulation options when EDUKE32_STANDALONE is defined

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

Rename console command 'sv_cleanup' to 'purgesaves', as sv_ is a prefix for cvars, not console commands

Reduce default snd_numvoices to 64 and reduce max to 128

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

glsurface.h/.cpp: change how the palette is handled and fix tinting/fading

Revert a number of changes from r6929 and r6930 that are no longer necessary.

Temporary workaround for palette or GL surface issue wherein launching Mapster32 into 2d mode produces a black screen until switching to 3d mode and back

Fix crash in Mapster32 when switching from GL 3d mode to 2d mode.

Use aligned memory allocation for GL surface

Fix issue with viewing the player sprite through a security camera

Fix inclusion of sdl_inc.h in Duke3D's config.cpp

Fix error with initputs symbol when linking the Build tools in some environments

Fix building the Build tools

Fix building with winlayer

Add glsurface.cpp/h and tilepacker.cpp/h to Visual Studio Project

Don't allow GL modes if GL Major Version is less than 2.

sdlayer.cpp: don't alter desktop composition using win_setvideomode() if we're creating an SDL window for rendering GL

When OpenGL is available, prefer using the new glsurface to blit the classic renderer's 8-bit buffer to the screen.

tilepacker.cpp: instead of maintaining the heap on each insertion, maxheap_buildHeap() on tilepacker_pack()

anim.cpp: timerUpdate() before setting the start time of the animation so that delays outside of animation playback won't cause animations to skip

astub.cpp: fix issue where globalpal was not declared if polymost.h was not included

palette.cpp: don't call uploadbasepalette() if USE_OPENGL is not defined

Fix conveyor belt speed in IM, but not Duke because it breaks gameplay

Rename KXDWN macro and GAMEFLAG_KXDWN to IONMAIDEN and GAMEFLAG_IONMAIDEN

Remove dead code branch from A_DoWaterTracers() and rename the function to Proj_DoWaterTracers()

Don't spawn hardcoded Duke3D debris/guts/glass sprites when compiled as EDUKE32_STANDALONE

Rework SE26 movement to function more like SE14 than SE24

Fix issues with running the game fullscreen on Windows 10 with high DPI setups

Fix SFLAG_WAKEUPBADGUYS

engine.cpp: fix issue introduced in r6905 where voxels with fractional scaling would not be handled correctly in Polymost

tiles.cpp: fix texcache.cpp:CLEAR_GL_ERRORS() hang on some drivers when trying to create GL textures for tiles when we have no GL context.

engine.cpp: fix issue with voxmodel_t voxels not having their scale set properly due to defs being processed before PolymostProcessVoxels()

engine.cpp: fix classicDrawVoxel() positioning bugs by:

Manually rebasing my r6899 over the formatting atrocity in r6895 broke my work.
