Added "Paste Properties Special" actions in "Classic" and "Visual" categories. They work the same way as "Paste Special" action.
Added: "Copy Properties", "Paste Properties" and "Paste Properties Special" options are now shown in the Edit menu if current classic mode supports them.
Changed, Paste Properties Special window: only options relevant to current map format are now displayed.
Changed, Paste Properties Special window, UDMF: all UI-managed options are now available.
Fixed: MAPINFO parser was unable to process "include" directives.
Fixed, General interface: selection info was reset to "Nothing selected" after few seconds regardless of current selection.
Fixed, Visual mode: thing bounding boxes were not updated when changing things positions using Randomize mode.
Fixed, Visual mode: event lines were displayed at incorrect height when entering Visual mode for the first time.
Fixed, Texture Browser window: when MixTexturesFlats Game Configuration option is disabled, textures/flats are no longer shown in the Used group when flats/textures with the same names are used in the map.
Fixed(?): probably fixed an exception some users reported when trying to initialize a Classic mode after switching from Visual mode with "Sync cameras" option enabled.
Changed, Game configurations, Thing Categories: a block must have at least one thing category property to be recognized as a thing category.
Changed, Visplane Explorer: the plugin now outputs more info when it fails to initialize vpo.dll.
Cosmetic, Thing Edit window, Doom/Hexen map format: adjusted UI layout so thing flags control no longer displays scrollbars in Hexen map format.
Internal: merged methods from UDMFTools into UniFields, removed UDMFTools.
Updated Inno Setup script (added VC++ 2008 SP1 distributive).
Updated ZDoom_DECORATE.cfg (A_CheckBlock).
Updated documentation (added "System Requirements" page).
Fixed, Texture Browser Form: well, I broke "Tab" key functionality again (in previous commit)...
Maintenance: changed curly braces style to match DB2 one (hopefully not breaking anything in the process...).
Maintenance: changed private method names casing to match DB2 one.
Visual mode: "Lower/Raise Floor/Ceiling" actions now work on surfaces with sector slopes.
Cosmetic: numeric textboxes, which support relative values, now have differently colored text and a tooltip.
Internal: renamed Sector.CeilingSlopeOffset to Sector.CeilSlopeOffset, Sector.CeilingSlope to Sector.CeilSlope to match their names with similar sector properties.
Thing Edit Form, UDMF: added controls for setting pitch, roll, scale, render style, fill color, alpha, health and score.
Visual mode, UDMF: UDMF scale is now applied when rendering sprites.
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.
Visual mode: added support for "fogdensity" and "outsidefogdensity" MAPINFO properties.
Sector Info panel now shows the number of sector's sidedefs as well as light and fade colors (UDMF only).
UDMF: Sector and sidedef flags are now copied/pasted when using "Copy Properties" and "Paste Properties" actions.
Fixed: in some cases default texture overrides were used even when corresponding option was disabled.
Sector Edit form: light and fade values were not saved when a value was pasted/entered into text box.
Sector Edit form: "reset value" button was not shown for light and fade values when selected sectors had different light/fade colors.
Reverted Open Map form changes from previous commit (my assumption that map marker is always empty was not correct...)
Updated documentation.
Tag Statistics form: you can now double click on Sectors, Linedefs or Things cell to select them, and right click to open their properties.
Texture size labels were displayed incorrectly in some cases.
Rewritten VerticesMode.DeleteItem() once again...
Vertex Edit form now works in realtime mode.
Vertex Edit form: ceiling and floor vertex offsets can now be cleared.
Added StairSectorBuilder plugin (I suppose some external plugins will stop working in GZDB because I've changed ButtonStep to float in ButtonsNumericTextbox a couple revisions ago...).
Preferences form: action description is now scrollable.
Changed background color of Sector Edit form.
Vertex' ZCeiling and ZFloor properties are now managed internally.
