godot/scene/3d/navigation_region_3d.cpp
smix8 c394ea518e Add more detailed Navigation Debug Visualization 
- Adds more customization options to ProjectSettings.
- Displays navregion edge connections and navigation polygon edges in editor and at runtime.
- Majority of debug code moved from SceneTree to NavigationServer.
- Removes the irritating debug MeshInstance child node from NavigationRegion3D and replaces it with direct RenderingServer API.
