What changed in EDuke32, build by build

Change OSD_CvarModified() to rely on a CVAR_MODIFIED flag set in osdcmd_cvar_set(), instead of merely comparing the current value to the default value. This leaves the storing of the default value (dval in osdcvar_t) in place for use in future features that haven't been programmed yet.

Remove camera distance from the calculation for how much to offset sprites to avoid z buffer fighting.

Fix linking of mdpause variable with POLYMER=0 in screens.c, exposed by Visual Studio. DONT_BUILD.

Fix STARTUP_WINDOW=0 on Windows so that the resource objects are built, but the editor's startup window is not. DONT_BUILD.

Extend STARTUP_WINDOW to GTK. DONT_BUILD.

Support vsync in classic mode (SDL 2.x only), and properly handle failure to enable "adaptive" vsync on systems that don't support it.

Fixes issue where freezing GREENSLIME repeatedly would increase the player's kill counter by one each time

Default internal frame wait counter to 17ms to match the default r_maxfps value of 60. Fixes issue where the framerate counter wasn't enforced after setting it to 60 and restarting the game.

Fix menu option for pixel doubling

Fixes issue where sounds weren't pausing when pausing the game

Fixes issue with picnum 0 sprites used as map geometry

Fixes an issue with enemies waking up when using security cameras

Add libxmp-lite support to Makefile.msvc.

Fix a couple of issues with savemapstate/loadmapstate.

Change default anisotropic filtering setting to the max for the user's system. DONT_BUILD.

Support building without a startup window through the Makefile. DONT_BUILD.

Add support for MOD, XM, IT, and S3M tracker music through libxmp-lite.

support sprite blending mode and statnum in clipboard.

Remove Menu_MouseWithinBounds() in favor of negating the result of Menu_MouseOutsideBounds().

Rename menu functions to what I consider to be more sane names. No other changes.

Add menu option to control r_maxfps, default r_maxfps to 60, add cvar for pixel doubling (r_pixeldoubling).

Remove disabling certain mouse features under debug builds. It makes mouse aiming unusable.

Amend r5911 to use undefinetile instead of only zeroing out the MIRROR tile's dimensions.

Extend undefinetile to also remove voxels, hightile (including skyboxes) and models.

Add vox_undefine().

Amend r5910 so that the problem is mitigated even when the map load takes place with a different renderer.

Revert a formatting change from r5725.

Move the nulling of the MIRROR tile to after defs are parsed so that tilefromtexture does not interfere with mirror function.

Clear wsprinfo[] upon map load. This should address some remaining instances of wall-ornamented sprite z-fighting.

To avoid potential compiler bugs when inlining inline assembly, remove the asm variants of msqrtasm and always use the C version. Compilers generate equivalent or better assembly, and the function is used exactly once, in a routine called during startup.

C-CON and M32script: Only accept hex literals beginning with '0' and not any other digit.

Fix the parser so tokens with 'x' or 'X' as a second character are only treated as hex constants when the first character is '0'. Introduced in r5822.

Fix the off-by-one error when printing line numbers.

SDL 2.0.5

Don't set the window icon from code if we are linked with SDL >= 2.0.5 on Windows, since it will now automatically use the first icon in the exe.

Add EDUKE32_SDL_LINKED_PREREQ macro.

Disable Windows thread naming because it interferes with debugging.

Implement "divscale" and "scalevar" (scale()) in C-CON and "scalevar" in M32script.

Fix improper matching of loop tags with initial substrings of them, and add proper support for LOOP as a synonym of LOOP_START.

Bump PSKYOFF_MAX from 4 to 8.

Add "yoffset" subtoken to "multipsky".

Re-enable the use of psky_t's yoffset.

Fix addlogvar command, broken in r5835.

GL .blend support.

In 8-bit, change the precedence of .alpha and .blend.

Cosmetic changes to some blend/alpha related code.

Minor changes to gamevar error handling

Exterminate the smurfs! This fixes the problem where everything in the game was drastically hue shifted on certain hardware configurations, particularly the Raspberry Pi.

Fix detection of menu sounds in EVENT_SOUND

Change default unfiltered texture mode to 0 (no mipmaps)

Fix clang Windows build. DONT_BUILD.

Fix mistake in r5862. DONT_BUILD.

Fix erroneous display of MESSAGES: ON when it should be OFF.

Fix TEST_SYNC_KEY macro to always return 1 or 0.

Allow an invocation like `make CC=clang-3.8` to work properly.

Fix undefined behavior: null pointer passed as argument which is declared to never be null

Loop optimizations in screencapture

Support saving specified CON arrays in map states

block ctrl-x and ctrl-shift-x from working if you have unsaved changes

Fix ghost tsprite bug introduced in previous commit.

Finish what r5484 started but got reverted in r5723. Cstat 1024 now works properly in Polymost without causing any side effects in Classic. It remains unimplemented in Polymer.

Reinstitute the cosmetic cleanups that should have been a separate commit from r5484 and were reverted in r5723.

Fix MIDI playback on Windows, broken in r5817.

Fix autoaim. Oops.

Cleanups

Fix warning: signed and unsigned type in conditional expression [-Wsign-compare]

Fix a bug in r5826 regarding display of the WWII GI rocket launcher.

Add bit 1 to action flags: use the viewpoint's position relative to the actor when calculating which rotation to display, instead of the viewpoint's angle, for viewtypes 2/3/4/8. 5/7 already do this.

Add an optional sixth parameter, a flags bitfield, to action definitions. Bump BYTEVERSION.

Enumify stuff having to do with action parameters.

I need to quit trying to be clever
