Memory issue: scene stuck in GLRenderLists

[Displee]

Dispose scene implementation is not finished. The scene should be removed from the GLRenderLists.lists on dispose, but it never is.

Three.js code: https://github.com/mrdoob/three.js/blob/r106/src/renderers/webgl/WebGLRenderLists.js#L163

function onSceneDispose( event ) {

var scene = event.target;

scene.removeEventListener( 'dispose', onSceneDispose );

delete lists[ scene.id ];

}

threekt code: https://github.com/markaren/three.kt/blob/master/core/src/main/kotlin/info/laht/threekt/renderers/opengl/GLRenderLists.kt#L39

override fun onEvent(event: Event) {
    val scene = event.target as Scene
    scene.removeEventListener("dispose", this)
}

Because the scene is never removed, memory gets filled up when doing heavy rendering.
