1) press the heart while the game is running
2) select a scene to live edit from the opened scenes
3) edit/add/remove nodes or resources, change their properties, etc.
4) watch changes reflected in running game, in all places this scene is
edited
5) It's not perfect obviously, but the aim of it is to try to reflect
your changes as best as possible in the running game.
-ability to edit multiple scenes at the same time
-resource internal IDs are now persistent, this makes multiple scene
editing possible but maaaaay result in file corruption bugs (tested and
could not find anything but possibility exists because core code
changed, report immediately if you find this).
-properly save settings, layout, etc when edited
-script editing is independent from scene editing now
-show a yellow box when a script belongs to the scene
-Added Navigation & NavigationPolygon nodes
-Added corresponding visual editor
-New pathfinding algorithm is modern and fast!
-Similar API to 3D Pathfinding (more coherent)
-=-=-=-=-
-Fixed problem with scaling shapes (#827), related to not taking scale in consideration for calculating the moment of inertia
-Added support for multiline strings (or comments) using """
-Save subscene bug, properties not being saved in root node (#806)
-Fix Crash in CollisionPolygon2DEditor (#814)
-Restored Ability to compile without 3D (#795)
-Fix InterpolatedCamera (#803)
-Fix UV Import for OBJ Meshes (#771)
-Fixed issue with modifier gizmos (#794)
-Fixed CapsuleShape gizmo handle (#50)
-Fixed Import Button (not properly working in 3D) (#733)
-Many misc fixes (though no new features)

-If re-importing from the "dependency changed" dialog, edited scene will keep the local changes.
-Imported scene will keep track of changes in the source asset
-Geometry changes in source geometry or nodes with a different transform will be updated.
-Materials will be kept if changed locally.
-New nodes added will be kept
-If nodes were reparented or renamed, they will still keep track
-Deleted notes will be restored, use the -noimp option to avoid this.
-In general, you can trust that if you do local modifications to the imported scene, they will not be erased after re-import.
-Erasing your changes is done by re-importing from the "Re-Import" menu, re-opening the "Import 3D Scene" dialog. This wil re-import fresh.
Overall, This should allow you to work on a scene and see changes made to 3D assets in real-time.
So Please test!!
-Object Manipulator Gizmo keeps proper scale in all windows and projections, (configurable on settings too).
-Manipulator gizmos for other objects (camera, shapes, etc) massively improved and bug-fixed.
-Manipulator gizmos are different for edited object and other objects.
-Properly highlight manipulator gizmo handles when hovered.
-Fixed bugs in fragment program when using more than 1 light together.
-Reload png/jpg files automatically in editor if edited externally.
-Added 4-stages Parallel Split Shadow Mapping, to improve shadow quality in large scenarios
-Added PCF13 to improve smoothness of shadow borders
-General optimization of directional light shadow mapping for Orthogonal,PSM and PSSM.
-Fixed normal mapping when importing DAE files, works nicely now.
