//
// HISTORY: 
// 1998/05/1	Initial Release
// 1998/05/13	Added ability to have a Pane with a control
// 1998/05/13	Added better support for TabControls
// 1998/05/14	automatically set Icon to IDR_MAINFRAME
// 1998/05/19	no flicker on restoring position in OnInitialUpdate
//				Changed procedure for load/save, see constructor
// 1998/10/02	Added support for Maximum (tracking) size
// 1998/10/02	Much improved handling regarding RELATIVE/GREEDY
//              /w critical minimum size
// 1998/10/02	turn on/off gripper at lower right corner
// 1998/10/05   Support for user defined minimum size for items
//              (was hardcoded 5 before)
// 1998/10/07   Fix for FormViews
// 1998/10/31	Support for SECDialogBar/CDialogBar
// 1998/10/31	simplified interface
// 1998/10/31	Advanced positioning options
// 1998/10/31	Added paneNull for empty Pane (former: NULL)
// 1998/11/20	Swapped ETSLayoutDialog constructor parameters
// 1998/11/20	Added Pane::addItemSpaceBetween 
//				[Leo Zelevinsky]
// 1998/11/24	Added fixup for greedy panes
// 1998/11/24	addItemSpaceBetween now subtracts 2*nDefaultBorder
// 1998/11/24	addGrowing() added as a shortcut for a paneNull
// 1998/11/24	simplified interface: no more PaneBase:: / Pane:: 
//				needed
// 1998/11/24	added FILL_* Modes
// 1998/11/24	improved maximum size handling for greedy panes
// 1998/11/25	Fixup of greedy panes caused infinite loop in some 
//				cases
// 1999/01/07	addItemSpaceLike() added
// 1999/04/03   Fixed ETSLayoutFormView memory leak
// 1999/04/07   Fixed ALIGN_xCENTER
// 1999/04/08   New simple stream-interface added
// 1999/04/09   Added support for an empty Status-Bar for resizing 
//              instead of a gripper in the lower right corner
//              [Andreas Kapust]
// 1999/04/11   New code for much less flickering, OnEraseBkgnd()
//              overidden for this task
// 1999/05/12   Split Layout code into understandable pieces and adding
//              a lot of comments
// 1999/06/20   ABSOLUTE_X + ALIGN_FILL_X expands item if there is any
//              left space (after all Abs/Rel/Greedy processing is done)
// 1999/10/06   Changed Load() and Save() to use WINDOWPLACEMENT
//              [Keith Bussell]
// 1999/11/18   Added possibility to add panes of the same orientation
//              to another pane. This merges both panes in one big
//              pane with the same orientation
// 1999/11/18   Added support for BCGDialogBar (only with BCG > 4.52!)
// 1999/11/25   Addes support for PropertyPages/Sheets. Uses some code
//              of a code submission from Anreas Kapust
// 1999/11/25   Renamed classes to ETSLayoutXXX
// 1999/11/25   Use CreateRoot() and Root() instead of m_pRootPane in
//              derived class.
// 1999/11/26   Added autopointer support. No need to use normal pointers
//              when defining layout anymore. Changed m_pRootPane to 
//              m_RootPane
// 1999/11/26   Bug in Fixup Greedy II with multiple GREEDY panes and one
//              of them min/max limited
// 1999/11/28   Fixed PaneTab::getConstrainVert() for ABSOLUTE_VERT
// 1999/11/28   Fixed itemFixed()
// 1999/11/28   Changed DWORD modeResize Arguments to layModeResize for 
//              better type safety. Added typesafe operator|
// 1999/12/04   Don't reposition window in UpdateLayout if it's a child
//              (as a child Dialog or PropertyPage)
// 1999/12/04   Erase Backgroung with GCL_HBRBACKGROUND (if available) 
// 1999/12/04   itemSpaceXXX() adds a NORESIZE item instead of ABSOLUTE_XXX
//              this will fix unwanted growing in secondary direction
//
// Version: 1.0 [1999/12/04] Initial Article on CodeProject
//
// 1999/12/10   Erase Backgroung within TabCtrl was 'fixed' badly. Reverted to
//              old working code
// 2000/02/02   When the Dialog is child of a View the class works correctly
//              now [Didier BULTIAUW]
// 2000/02/15   Combo-Boxes were not working correctly (in all modes!)
// 2000/02/17   aligned SpinButton Controls (with buddy) now handled 
//              automatically
//              !! do not add such a control to the layout !! it is always
//              reattached to its buddy.
// 2000/02/17   changed some cotrol class names to the defined constants
//
// Version: 1.1 [2000/02/17]
//
// 2000/02/25   Fixed auto alignment of SpinButton Controls to only affect 
//              visible ones
// 2000/02/27   Put all the classes into the namespace 'ETSLayout'
// 2000/03/07   Fixed growing Dialog after minimizing and restoring
// 2000/05/22   Whole Statusbar (Gripper) is not excluded anymore in EraseBkgnd()
//              instead only the triangular Gripper is excluded
// 2000/05/31   Fix for PropertySheets with PSH_WIZARDHASFINISH [Thömmi]
// 2000/05/31   Fix for UpDown-Controls with EditCtrl Buddy in PropertyPages.
//              These were not repositioned every time the page is being show
//              until the first resize
// 2000/07/28   Problems with resizing ActiveX Controls fixed [Micheal Chapman]
// 2000/07/28   Some strings were not properly wrapped with _T()
// 2000/08/03   Check for BS_GROUPBOX was not correct as BS_GROUPBOX is more than one Bit
// 2000/08/03   New override AddMainArea added to ETSLayoutPropertySheet in order to 
//              have a hook for additional controls in a PropertySheet (besides the Tab)
// 2000/08/03   New override AddButtons added to ETSLayoutPropertySheet in order to 
//              have a hook for additional controls in the bottem pane of a PropertySheet
// 2000/08/03   Removed the need for DECLARE_LAYOUT
//
// Version: 1.2 [2000/08/05]
