 | These are the procedures which layout and display embedded window objects. |
 | An embedded window is defined by a rectangle size, a module name, a class  |
 | name, and data.															  |
 |																			  |
 | The module and class names are descriptions of where to get the code which |
 | handles the maintainance of the window.	Exactly how these are implemented |
 | is platform-specific.													  |
