* Still to do:
* Properly handle effects (disable 3D effects) for layers
* Handle hot reloading properly
* Avoid duplicating the configuration of the custom object inside each object created from it. Instead, only store the modified values.
* Add a "Extract as a custom object ("prefab")" when selecting instances in a scene.
* Add a dialog to give choice between 2D or 3D object when creating one.
* Make sure "behavior shared data" are properly handled (physics, pathfinding...)
* Check if we need to give an expression to translate coordinates from the parent to the local custom object.
* Ensure a deleted custom object does not break the editor

- Custom objects like the 3D particle emitter can be used as any other 3D object
- with the same set of actions and conditions thanks to the 3D capability
- in the scene editor, their Z position and 3D rotations can be changed
- Fix child creation in `doStepPostEvent` function
* This provides new 3D objects: 3D Box (perfect to create walls, floors, or billboards) and 3D Model (to import objects created in a 3D modeling app).
* 2D and 3D can be mixed in a same game. Each layer of a game can contain 2D objects, 3D objects or a mix of both.
* This allows to build 2D games, 2.5D games and full 3D games: platformers, racing games, FPS, hyper casual games. It's easy to start adding 3D objects to an existing 2D game.
* You can set up a light by adding an ambient light and/or directional light in the effects of a 3D layer. 3D objects can be configured to react to light or ignore it.
* In the future, support for 3D objects will be improved: light objects, animations, etc...
