Added, "Check polyobjects" error check: added a check for matching Polyobject and Mirror Polyobject numbers of Polyobj_StartLine action.
Changed, Visual mode: anisotropic filtering is now always applied (previously it was applied only when bilinear filtering was enabled).
Fixed, Visual mode: in some cases light values were incorrectly transferred between 3d floors and regular floors/ceilings.
Fixed, ACS parser: includes for each library must be stored separately (fixes inability to compile a script with an included library, which in turn includes files already included by the script).
Fixed, Visual mode: glow effect was not updated when changing sector textures using the "Select Texture" action.
Browse Textures/Flats window: when textures list is focused, you can now start typing to change the Filter.
Changed, Visual mode: changed thing fog calculation logic. Should be closer to GZDoom now.
Fixed, GLDEFS parser: "height" texture parameter was not treated as optional.
Fixed, text lump parsers: in some cases incorrect line number was displayed in error and warning messages.
Fixed, Visual mode: glow effect was not applied to sectors with 3 sidedefs.
Fixed, Visual mode: in some cases glow effect was not updated when replacing textures.
Fixed, general interface: "Full Brightness" button state was not updated during map loading.
Fixed, Drag Linedefs/Vertices/Sectors/Things modes: positions of line length labels were not updated while panning the view.
Cosmetic: added a bunch of new icons.
Cosmetic: changed Visual mode crosshair.
Visual mode: added support for "Transfer Floor Brightness" (210) effect.
Visual mode: added support for "Transfer Ceiling Brightness" (211) effect.
Visual mode: changed the way thing brightness is calculated. Should be closer to GZDoom now.
Sector Edit Form: you can now enter "++" or "--" into "Height Offset" input to raise or lower sectors by their height.
Cosmetic fix in ZDoom_linedefs.cfg.
Fixed, Visual mode: floor brightness was calculated incorrectly when "Disable Light Effects"/"Restrict light inside" 3d floor flags were used and the floor had "lightfloor" property.
Fixed: "lightabsolute" flag was accessed incorrectly in previous commit.
