CanvasRenderer.OnTransformChanged is called on disabled UI objects
When a transform with children CanvasRenderers is changed/moved CanvasRenderer.OnTransformChanged is called for all of them even if they are disabled causing huge CPU spikes.
The project attached contains a scene with 1000x4 such objects. Profiler shows a lot of time wasted in CanvasRenderer.OnTransformChanged every frame.

This makes using the UI system in VR projects (ui's that move with the camera) impossible. Please fix this!

Issue exists on Unity 5.3 too and probably before this. Please it could be nice to do something or at least review this.

There is not so good but working workaround. You can place inactive children from moving node to static one.

Is there ANY workaround for that? I have really big performance problems because of that on iPad 3.
