Keeps current API as-is by defaulting to the new BorderAuto BorderStyle
which keeps the default borders on Windows and defaults on none on Frames.
Allows setting a Window Border to BorderNone for a frameless Window.
Need to allow setting the border default in the Window Manager to avoid
the border from being drawn and then removed.

In order to guarantee BaseControl and Control are fully comparable in the
BaseControl level this patch introduces a refID interface, so the objects
can safely be comparable based on this interface.
