 * $Log:: /JP2_PC/Source/Shell/AppShell.cpp                                                    $
 * 
 * 14    4/28/98 11:31p Agrant
 * Porting code for world database reset
 * 
 * 13    2/05/98 7:31p Agrant
 * More porting code for world database
 * 
 * 12    96/11/08 18:45 Speter
 * Added AddMenuItem(), hmenuAddSubMenu(), and bContinuous() functions.
 * 
 * 11    96/11/06 11:48 Speter
 * Reordered data to make WindowsEvent overridable again.  Now AppShell handles the key states,
 * and WindowsEvent calls CAppShell::RawKeyPress.
 * 
 * 10    96/11/05 17:43 Speter
 * Changed Repaint back to old version, where it explicitly calls WinShell's PaintWindow.
 * Hand bKeyState() call off to function in AppEvent.
 * 
 * 9     96/10/30 15:18 Speter
 * Resurrected AppEvent.cpp (but not AppEvent.hpp), moved WindowsEvent() from AppShell.cpp to
 * AppEvent.cpp.  This allows WindowsEvent to be redefined in another module
 * 
 * 8     96/10/28 14:51 Speter
 * Merged AppEvent module into AppShell.  Now, both regular and virtual shell-handling functions
 * are handled through single CAppShell class.
 * 
 * 7     96/10/25 14:33 Speter
 * Changed repainting strategy.  Now repaint on WM_PAINT message, ignore WM_ERASEBKGROUND.
 * AppShell::Repaint() function invalidates the window, generating WM_PAINT.  This allows
 * Repaint() to be called during any handler function.
 * 
 * 6     7/19/96 10:58a Pkeet
 * Changed include files for shell files moved to 'Shell.'
 * 
 * 5     7/18/96 3:16p Pkeet
 * Altered to rely on 'Render.hpp' instead of 'WinShell.hpp.'
 * 
 * 4     7/16/96 11:29a Mlange
 * Moved several files to different directories, updated includes.
 * 
 * 3     96/05/30 17:48 Speter
 * Added HideCursor function.
 * 
 * 2     96/05/16 18:19 Speter
 * Added separate version of TerminateShell to namespace.
 * Corrected some comments.
