+/// behind this is that the SubSceneOverride does not take into account the visibility state of the shape.
+/// During an update loop of the SubSceneOverride, all SceneShapes will be queried for their update state,
+/// regardless their visibility in the scene. This query is slow and we get a huge drop in performance
+/// when having a huge amount of SceneShapes in the scene.
+/// This is considered to be a bug in the ViewPort 2 API. Our attempts to rewrite the code to use
+/// "MPxGeometryOverride" or "MPxDrawOverride" prove themselves as unstable or not suitable for our
+/// use case, why we decided to use this "hackery" and not register a proxy of the SceneShape for
+/// drawing at all
