ZoneBuilder/Source/Core/VisualModes/VisualThing.cs
MaxED 17abdf5186 Added Rendering toolbar items to the View menu.
Merged "Toggle models, dynamic lights and fog rendering" and "Toggle Geometry Effects" actions into "Toggle Enhanced Rendering Effects" action.
Removed "Dynamic light size" and "Dynamic light intensity" settings.
Updated documentation ("Rendering toolbar" page).
