What changed in EDuke32, build by build

Add voxels option to menu, if at least one has been defined

Fix bug where "standing" on top of a sprite structure underwater would cause the player to act as if they were no longer underwater

Attempt to work around odd behavior when attempting to use stuff like wall aligned sprites with the new version of clipmove

Tweak the fatal engine initialization error and game already running dialog boxes a bit

Polymost projection changes to correct the perspective in widescreen and ultrawide resolutions.

Fix Mapster32 bug with 2d3d mode ambient sounds

gameexec.cpp: allow G_ShowView() to execute regardless of the state of g_screenCapture.

sector.cpp: ensure that if scripts have told us not to render normally to the tile, that we still handle restoring our target & setting up the tile appropriately for what the script may have rendered

engine.cpp: make renderSetTarget() more robust so that passing an xsiz or ysiz <= 0 is not accepted and can't cause a segmentation fault

polymer.cpp: fix issue where assert could fail due to HUD model sprites having an owner >= MAXSPRITES

polymost.cpp: Fix issue where tiles whose dimensions had grown would not have their sizes updated in GL and could fail to update their texture data

polymost.cpp: If a tile in the tilesheet is large enough to fit a redefined tile, use that space rather than allocating a new texture

polymost.cpp: if an indexed colour tile is being reloaded, changed dimensions, and no longer matches the calculated tilesheets, generate a separate texture for it.

This adds back in the engine's old automapping feature

Don't blow away wall cstat bit 14 for use as a temp flag in the editor

Work around an issue with far plane clipping with voxels without mipmaps in software mode

Emulate slope overflow in Polymost in order to match the rest of the engine's slope algorithms

Hopefully work around more Polymost polygon leakages

Fix issue rendering TROR when the camera's z coordinate is right on the portal

polymost_scansector(): avoid using a culling method not designed for voxels when handling 1-sided wall aligned sprites that have voxel replacements

Fix rendering skyboxes to a tile by altering renderSetTarget() & renderRestoreTarget() to set & reset xdim & ydim so that G_ShowView() can render while a render target is set,

Patch from Nuke.YKT to work around precision-based inaccuracy problems in Polymost TROR

Add MERGE_NODES macro for Polymost... this will be used in the following commit

Patch from Nuke.YKT to clip bunches to screen boundaries in Polymost

Patch from Nuke.YKT to fix sloped floor and ceiling textures wiggling around in Polymost

Revise r7835: instead of not testing wall sprites, we'll just ignore the side blockers

Don't check clip objects for sprites in the keepaway() loop in clipmove()

Fix additional clipmove() issue

Additional clipmove() reworks

Switch a few iterators in clipmove() from int to native_t

clipmove() patch from Nuke.YKT:

Fix mirrors in Polymer

Add updatesectorneighbour() and updatesectorneighbourz() and make them accessible to CON to allow searching for nearby neighbouring sectors from a known sector.

Fix edge case where mirrors & TROR could interact and render over skyboxes in the classic software renderer

polymost1Frag.glsl: Fix warning C7572: OpenGL requires extension names to begin with 'GL_'

Tweak previous commit so clipmove takes precedence over getzrange
