Get the AABB (axis aligned bounding box) for the object.
The default implementation uses either the position/size of the object (when angle is 0) or hitboxes (when angle is not 0) to compute the bounding box. Result is cached until invalidated (by a position change, angle change...).

Return at least all the hit boxes that overlap a given area.
The hit boxes don't need to actually overlap the area, (i.e: it's correct to return more hit boxes than those in the specified area) but the ones that do must be returned.

Called to reset the object to its default state. This is used for objects that are
"recycled": they are dismissed (at which point onDestroyFromScene is called) but still
stored in a cache to be reused next time an object must be created. At this point,
reinitialize will be called. The object must then work as if it was a newly constructed
object.
To implement this in your object:
gdjs.YourRuntimeObject.supportsReinitialization = true; to declare support for recycling.reinitialize. It must call the reinitialize of gdjs.RuntimeObject, and call this.onCreated();
at the end of reinitialize._runtimeScene, _nameId, name and type are guaranteed to stay the same and do not
