solved TransformNode on GUI3D PlanePanel causes overlap

[ssaket]

Hi Devs, 

I am trying to rotate PlanePanel using TransformNode, but one strange thing that I observed is it's causing overlap between the meshes/buttons. Am I missing something here ?

Hiya S!  https://www.babylonjs-playground.com/#HB4C01#54

In lines 43-46, I waited until scene ready (til after the panel rendered for the first time)... and THEN did the rotation.

I don't know if it's operating correctly, but at least we know a work-around and a bit about the reason for the problem.

update:  PG #55 tries to eliminate the "flash" of un-transformed button-text... using a contorted button-by-button isVisible loop.

Thanks @Wingnut.
Though still strange to me, why it is not able to apply transform properly without using scene.onReadyObservable, Is it a bug ?

Before rotation this will work, too:

anchor.computeWorldMatrix();

Hi everyone;

Is it possible to rotate the part on the bottom right in this example to form a corner?
