Each of these is designed to utilize their respective button rectangles. The public (void) versions simply call the internal protected ones with the button rectangle.

This returns the "footprint" of the decorator, i.e. the area which is occupied by the window which is is the border surrounding the main client rectangle. It is possible to have oddly-shaped window borders, like ellipses and circles, but the resulting performance hit would reduce the said decorator to a novelty and not something useable. All versions are to construct an SRegion which the border occupies. This footprint is permitted to include the client rectangle area, but this area must not be actually drawn upon by the decorator itself. The default version returns the frame which encompasses all other rectangles - the "frame" member which belongs to its window border.</P>

These four are for general start and stop procedures. The constructor and destructor concern themselves with the internal members common to all drivers, such as the current cursor and the access semaphore. Subclasses will probably end up using these to handle memory allocation-related issues, but likely not much else. Initialize() and Shutdown() are for general setup internal to the module. Note that if Initialize() returns false, the server will not use the module, call Shutdown(), and then delete it as accordingly.</P>
