Fixed: PairedFloatControl had incorrect initial link icon.
Internal, AngleControl: rewritten AngleChanged event so it behaves like the rest of custom events.
Updated GZDB icon.
Import Wavefront .obj as Terrain mode: floor height of each created sector is now set to the average height of an .obj polygon it was created from.
Import Wavefront .obj as Terrain Settings window: added "Use slopes" checkbox. When enabled, the mode will create slopes using vertex height offsets (UDMF) or Floor Vertex Height things (1504).
Fixed, Visual Mode: things were rendered at wrong height after using "Lower/Raise Height" actions in sectors with sloped floor (or ceiling for ceiling-aligned things)
Fixed: info panel was not updated after switching to another Edit Mode.
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.
Consistency, Randomize Sectors form: persistent settings are now saved only when applying changes done in the form (e.g. in the same conditions as in Randomize Things / Vertices forms).
Fixed: Randomize Sectors, UDMF: vertex height changes were not undone properly after using the mode (I broke it in r2101).
Fixed: Randomize Sectors: floor/ceiling textures can not be used as lower/upper textures when "MixTexturesAndFlats" is disabled. In this case the corresponding option is now changed to "Use default texture".
Added icons for "Save Screenshot" menu items.
Development: "Save Screenshot (active window)" action will work on a child Form only if it is inherited from DelayedForm.
Renamed "Toggle dynamic lights rendering" action to "Show dynamic lights".
Changed: "Show dynamic lights" action now toggles between available dynamic light rendering modes.
Renamed "Toggle models rendering" action to "Show models".
Changed: "Show models" action now toggles between available model rendering modes.
Removed "Toggle dynamic lights animation" and "Render selected/all models" actions.
Fixed, Randomize Sectors form: selection highlight was not updated after applying the changes when the form was shown in Sectors mode.
Consistency: selection is now cleared after applying changes done in Randomize Things and Randomize Vertices forms.
Fixed, Classic modes: sprites of things with attached models were not rendered when model rendering was disabled.
Updated documentation.
Randomize mode: randomized pitch, roll and scale can now be applied to things.
Randomize mode: removed "Relative" option, because results with this option enabled were almost the same as without it.
Classic modes, model rendering: selected models are now rendered using highlight color, so they no longer blend with thing rectangle/circle.
Model rendering, UDMF: scale was applied incorrectly to models with pitch or roll.
Updated documentation.
"Preferences -> Editing -> When splitting a linedef" setting is now always used when splitting linedefs.
"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.
Draw Curve Mode: added settings panel.

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.

Classic modes: view was not redrawn after "Test map from current position" action.
"Test map from current position" action: incorrect player start was used when a map had several Player 1 Start things.
