 * $Archive: /CodeJockey/Include/CJDockContext.h $
 *
 * $History: CJDockContext.h $
 * 
 * *****************  Version 9  *****************
 * User: Kirk Stowell Date: 8/31/99    Time: 1:11a
 * Updated in $/CodeJockey/Include
 * Updated copyright and contact information.
 * 
 * *****************  Version 8  *****************
 * User: Kirk Stowell Date: 7/25/99    Time: 12:42a
 * Updated in $/CodeJockey/Include
 * 
 * *****************  Version 7  *****************
 * User: Kirk Stowell Date: 7/18/99    Time: 10:17p
 * Updated in $/CodeJockey/Include
 * Cleaned up inline functions, and import/export macro so that class will
 * be imported when linked to, and exported at compile time.
 * 
 * *****************  Version 6  *****************
 * User: Kirk Stowell Date: 6/09/99    Time: 8:33p
 * Updated in $/CodeJockey/Include
 * Ioannhs Stamatopoulos (Yiannhs) [ystamat@mail.datamedia.gr] - Extended
 * docking windows, removed ::GetSysColor(...) calls and WM_SYSCOLORCHANGE
 * message handler, this is now automatically handled by the base class.
 * Added redraw flags to the create method and modified paint and layout
 * handlers to reduce flicker and un-necessary command handling. Dragging
 * rect now reflects actual control bar docked size. Added "flat" look to
 * the control bars, the control bars can now use the classic DevStudio
 * look, or use flat gradient gripper, borders and frame buttons. Overall,
 * docking windows now handle dragging, docking and floating much better,
 * and behave more like DevStudio.
 * 
 * *****************  Version 5  *****************
 * User: Kirk Stowell Date: 4/14/99    Time: 12:57p
 * Updated in $/CodeJockey/Include
 * Daniel Harth [danielh@mail.matco.ro] - Added support for diagonal
 * sizing. 
 *

 * 
 * *****************  Version 3  *****************
 * User: Kirk Stowell Date: 3/10/99    Time: 12:56p
 * Updated in $/CodeJockey/Include
 * Added support for toggle docking.
 * 
 * *****************  Version 2  *****************
 * User: Kirk Stowell Date: 3/03/99    Time: 12:54p
 * Updated in $/CodeJockey/Include
 * Scott Killen [s_killen@yahoo.com] - If your frame is not your main
 * window in your app, you cannot dock a floating CCJControlBar. Changed
 * (CFrameWnd*)AfxGetApp()->m_pMainWnd to (CFrameWnd*)m_pDockSite in
 * CanDockDockBar() and DockSizeBar()
 * 
 * *****************  Version 1  *****************
 * User: Kirk Stowell Date: 1/12/99    Time: 12:53p
 * Created in $/CodeJockey/Include
 * Initial creation to add side-by-side docking support for CCJControlBar
 * class.
