NodeIndicator was trying to access properties from the Material attached
object. However, that one was shadowed by the Material type from
Quick3D. Avoid this by importing Controls into a namespace for
disambiguation purposes.
Also avoid a warning about mismatched types by explicitly casting
"parent" to a View3D before assigning it to a property of that type.
