	/**
	* Implements the LightweightPeer interface for use in lightweight components
	* that have no native window associated with them. This gets created by
	* default in Component so that Component and Container can be directly
	* extended to create useful components written entirely in java. These
	* components must be hosted somewhere higher up in the component tree by a
	* native container (such as a Frame).
	*
	* This implementation provides no useful semantics and serves only as a
	* marker. One could provide alternative implementations in java that do
	* something useful for some of the other peer interfaces to minimize the
	* native code.
	*
	* This was renamed from java.awt.LightweightPeer (a horrible and confusing
	* name) and moved from java.awt.Toolkit into sun.awt as a public class in
	* its own file.
