| The PhysicalDrawingSurface interface provides a common interface
which can be implemented by all of the objects which provide
implementation-specific information about the physical surface
upon which a DrawingSurface resides. There are no common methods
for all of these objects to implement, thus this interface is
empty. This interface merely exists to provide a common root type
for all of the possible objects that can be returned from the
DrawingSurfaceInfo.getSurface() method under different implementations.
The caller must be able to recognize the specific type of the
PhysicalDrawingSurface object in order to render directly to
that surface. Many of the physical handles will be usable only
by native code which accesses platform-specific drawing interfaces.
