* 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

* Only the first scene and global objects resources (images, sounds, 3D models etc...) will be downloaded during launch of the game. This usually allows for a very fast loading time.
* Other scenes resources will continue to load in the background. It has no impact on the game performance as this is done on other threads by the browser or the engine running the game.
* Scenes are loaded in the order they are listed in the project manager.
* You can also use actions and expressions to prioritize a scene (if it's known that a level will be needed soon for example) or read the current loading progress. This allows to create lightweight scenes that can act as custom loading screens. Otherwise, the launch loading screen will be shown if a scene is still loading when launched.
