* This opens the path to multiple performance improvements (faster WebGL rendering, and then WebGPU rendering) as well as optimised resources loading in the future.
* It makes the same boxes as the tilemaps collision mask object to ease positioning.
* If the extra margin is not intended the right size can be set with Tiled.
* The collision mask is read from the tile maps exported by Tiled 1.9+.
* Several collision masks can be used for instance to have platforms and ladders.
