What changed in EDuke32, build by build

Disable G_FadeLoad because it doesn't work in any renderer and only causes glitches.

Another attempt at fixing Polymost z-fighting. Probably still sucks! :)

fix texture panning floatiness on slight slopes

Move duke3d and engine directory definitions to their proper spots, as they no longer need early definition after the great repository rearrangement.

Fix interpolation of sprites in sectors with SE_31_FLOOR_RISE_FALL

Improve a couple of tagged sector warning messages. DONT_BUILD.

Factor out common uses of COMMONFLAGS, COMPILERFLAGS, and LINKERFLAGS into COMPILER_* and LINKER.

Fix disabling the Polymer checkbox in the Win32 startup window when POLYMER=0.

Use the override keyword when implicitly disabling Polymer and libvpx when USE_OPENGL=0.

This seems to fix a Polymost rendering error in which certain polygons touching the sides of the screen would fail to render from some angles. YMMV.

Remove red/blue 3d mode from Polymost. This hadn't been enabled in a long time and I'm not sure if it even worked anymore. DONT_BUILD.

Rename E_PostInitTables back to E_PostInit and move it back to where it belongs in engine.c (i.e. preinitengine, initengine, "postinitengine"). It should not have been changed.

Fix transparent masked walls in Polymost

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.

Fixes issue with picnum 0 sprites used as map geometry

support sprite blending mode and statnum in clipboard.

Add #ifdef USE_OPENGL forgotten in r5024 that causes an OOB access in scansector() and glitchy mirrors with USE_OPENGL=0.

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.

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

GL .blend support.

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

Potentially speed up drawing md3s with transparency in Polymost

Remove the Polymer aspect ratio option, as it was always broken, and I don't know what purpose it has besides configuring non-square pixel stretching, which we have a long way to go in terms of configuring anyway.

Some float optimizations in the engine.

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.

Fix Polymer breakage

The great cleanup continues. This one also adds a new feature, SFLAG_WAKEUPBADGUYS. When awoken (changed to an active actor), any sprite with this flag set will wake up any enemy it has line of sight with.

add home/end modifier keys to 3d mode slope keys ([ and ]), plus a third increment modifier (home and end at the same time)
