UltimateZoneBuilder/Source/Core/Rendering/Renderer3D.cs
MaxED deb43343bb Visual mode: "Fit Textures" action can now fit textures across multiple selected surfaces. A number of times to repeat a texture can now be specified.
Visual mode: removed "Fit Texture's Width" and "Fit Texture's Height" actions.
Visual mode: "Auto-align texture offsets" actions were incorrectly aligning double-sided middle walls in some cases.
Visual mode: "Auto-align texture offsets" actions now align non-wrapped double-sided middle walls to vertical offset closest to their initial vertical offset.
Visual mode: middle parts of double-sided walls were ignored when Shift-selecting walls.
Nodebuilders/Game configurations: GL nodes definitions were missing from game configurations.
Nodebuilders/Game configurations: "~MAP" wildcard can now be a part of a lump name. 
Nodebuilders: GL nodes were not properly handled by the editor.
Main Window: the window is now moved into the view when stored position is ouside of screen bounds. 
Classic and Visual modes: changing thing pitch was ignored in some cases.
Visual mode: raising and lowering a thing with "+SPAWNCEILING" flag now works the same way as when raising/lowering a regular thing.
Visual mode: using "Raise/Lower Floor/Ceiling to adjacent sector" actions on a thing with "+SPAWNCEILING" flag now works the same way as when using them on a regular thing.  
Rendering: even more fixes to MODELDEF and UDMF properties-related model rendering logic.
Internal, ResourceListEditor: rewritten resource validation check in a more OOP-ish way.
Configurations: fixed an infinite loop crash when a file was trying to include() itself.
UDMF thing flags: added Skill 6-8 to the flags list (because there are thing filters for these).
ZDoom_ACS.cfg: added definitions for SetTeleFog and SwapTeleFog.
ZDoom_DECORATE.cfg: added definitions for A_SetTeleFog and A_SwapTeleFog.
Updated ZDoom ACC.
Updated documentation.
