Restore default rendering behavior of Scene3D
Recent change in Scene3D was made to stop it rendering when it
was hidden. However this means it no longer can be used as a hidden
item in combination with an OpacityMask.
Revert default behavior to always draw and introduce an environment
variable to let the user stop rendering.
5.15 will add a property to control this properly.
