window as a native reference rather than relying on the calling

application to have created the parent window as an nsIWidget. This

value will be ignored (should be nullptr) if an nsIWidget is passed in to

the parentWidget parameter.
|

@param parentWidget - This allows a system to pass in the parenting widget.

This allows some objects to optimize themselves and rely on the view

system for event flow rather than creating numerous native windows. If

one of these is not available, nullptr should be passed.
