- Move most properties from TileMap to TileSet, - Make TileSet more flexible, supporting more feature (several collision layers, etc...), - Fusion both the TileMap and TileSet editor, - Implement TileSetSources, and thus a new way to index tiles in the TileSet, - Rework the TileSet and TileMap editors completely, - Implement an editor zoom widget (and use it in several places)
