make a ondestroy ?

[jeromeetienne]

good use case, no need for this._callback. use the js closure all the way

    var callback    = world.loop().hook(function(){
        cubeCamera.updateCubeMap( world.tRenderer(), world.tScene() );
    });

    sphere.on('destroy', function(){
        world.loop().unhook(callback)
     })

and encourage people to call destroy

[jeromeetienne]

same for .add/remove ?

[jeromeetienne]

Some localise experimentation, in various object where i dispatch 'destroy on destructor

Not inheritance infolved

Works well
