Interface: added info messages for several toolbar toggles.
Interface: made Brightness icon more readable when using dark windows themes.
Internal: UDMF sector slopes and offsets are no longer stored in sector.Fields. Use sector.FloorSlope, sector.FloorSlopeOffset, sector.CeilingSlope and sector.CeilingSlopeOffset.
Sectors mode: changed Alt-key handling. Now it only enables "snap to grid increment" mode.
Things mode: "snap to grid increment" mode now works in this mode.
Updated documentation.
Visual mode: real floor was colored by 3d floor's color even when it was below real floor.
Action Browser form: keyboard focus is now set to Filter text box by default.
Linedefs Mode: "Flip Linedefs" action now tries to align linedefs, so their front (or back) point towards the same sector.
Sectors Mode: "Flip Linedefs" action is now available form this mode, and it will also try to align linedefs, so their front (or back) point towards the same sector.
Preferences: added "Capitalize texture names" option (located in Preferences -> Appearance -> Additional options). When disabled, the casing of displayed texture names will match filenames for textures loaded form TEXTURES or pk3/pk7/folder resources.
Textures Browser: added support for displaying long texture names.
Errors list is now cleared when reloading resources.
Visual mode: added basic support for sector slopes (no UI for that feature yet).

Added Thing Statistics form (Edit -> View Thing Types...), which shows all loaded thing types with some additional info.
Visual mode: sprites with negative ScaleX and positive ScaleY were not rendered properly.
Classic modes: display was not updated after loading a sprite.
Current testing engine change was not saved on closing the program when no other game configuration settings were changed.

"Preferences -> Editing -> When splitting a linedef": added "Reset X and Y" option.
"Preferences -> Editing -> Auto-align textures of newly created linedefs" option now works in a more intelligent fashion.
Make Door action: door and track textures are now stored while the editor is running.
Edit Selection Mode: pasted geometry was not merged with the rest of the map if the selection was not modified before applying the mode.
Make Door action: made Make Door form a bit smaller.

Error Checker mode: added "Check missing flats" check.
Error Checker mode: fixed several descriptions.
Sprite patches for sprites defined in TEXTURES are now loaded from Sprites namespace.
Some of my older texture alignment code didn't work properly when strict texture/flat handling ("mixtextureflats" game configuration flag set to false) was enabled.
Fixed some incorrect checks for missing texture ("-").
Moved settings for "Draw [stuff]" modes to the top toolbar.
Added hints for Draw Grid mode.
Fixed a status message update bug introduced in previous commit.
When you try to change floor/ceiling texture offsets in Doom/Hexen map formats, a warning is displayed in status bar (instead of spamming you with message windows).
Mode actions toolbar is now auto-hidden when there are no buttons to display.
Draw Curve Mode: added settings panel.
Sectors mode: added "Make Door" button to the toolbar.
Swapped Side panel and Info panel z-order.

Interface: grouped stuff in "Modes" menu a bit better.
Interface: added "Draw [stuff]" buttons to modes toolbar.
Interface: reorganized main menu. Hope it makes more sense now.
API: added General.Interface.AddModesButton() and General.Interface.AddModesMenu(), which can be used to add buttons to specific group in "Modes" toolbar and menu items to specific group in "Modes" menu, so actions, which behave like an editing mode, but are not part of one can be added there.
Game Configurations: added "fixedrotation" property to "Polyobject Anchor" (9300), "Polyobject Start Spot" (9301), "Polyobject Start Spot (crush)" (9302) and "Polyobject Start Spot (hurts to touch)" (9303) actors.
Color Picker plugin: moved plugin button to "Modes" toolbar group.
API: added ToolbarSection.Modes property, which can be used in MainForm.AddButton() to add a button to Modes group.
Removed a bunch of unused variables.
Configurations: all 64 game configuration are now available by default.
Game Configurations window: game configurations can now be disabled. This setting is mostly cosmetic. When a game configuration is disabled, it won't be shown in "game configuration" dropdowns in New\Open Map Options and Map Options windows. If a map's .dbs file specifies a disabled configuration, it will be picked as a map configuration anyway.
Linedefs mode: vertex insert preview logic used Highlight range instead of Stitch range (which is used when draw mode engages).
Visual mode: double-sided middle textures were not selected when using "Select" action with "with same texture" modifier.
Textures: some optimizations in patch blending code.
ZDoom ACS script configuration: added definitions for StrLeft, StrMid and StrRight functions.
