/*
 * Rebar control    rev 8b
 *
 * Copyright 1998, 1999 Eric Kohl
 *
 * NOTES
 *   An author is needed! Any volunteers?
 *   I will only improve this control once in a while.
 *     Eric <ekohl@abo.rhein-zeitung.de>
 *
 * TODO:
 *   - vertical placement
 *   - ComboBox and ComboBoxEx placement
 *   - center image 
 *   - Layout code.
 *   - Display code.
 *   - Some messages.
 *   - All notifications.

 * Changes Guy Albertelli <galberte@neo.lrun.com>
 *  rev 2,3,4
 *   - Implement initial version of row grouping, row separators,
 *     text and background colors. Support additional messages. 
 *     Support RBBS_BREAK. Implement ERASEBKGND and improve painting.
 *  rev 5
 *   - implement support for dragging Gripper left or right in a row. Supports
 *     WM_LBUTTONDOWN, WM_LBUTTONUP, and WM_MOUSEMOVE. Also support 
 *     RBS_BANDBORDERS.
 *  rev 6
 *   - Fix or implement notifications for RBN_HEIGHTCHANGE, RBN_CHILDSIZE.
 *   - Correct styles RBBS_NOGRIPPER, RBBS_GRIPPERALWAYS, and RBBS_FIXEDSIZE.
 *   - Fix algorithm for Layout and AdjustBand.
 *
 * rev 7
 *   - Fix algorithm for _Layout and _AdjustBand.
 *   - Fix or implement RBN_ENDDRAG, RB_MOVEBAND, WM_SETREDRAW, 
 *     WM_STYLECHANGED, RB_MINIMIZEBAND, RBBS_VARIABLEHEIGHT, RBS_VARHEIGHT,
 *     RBBS_HIDDEN, WM_NOTIFYFORMAT, NM_NCHITTEST, WM_SETREDRAW, RBS_AUTOSIZE,
 *     WM_SETFONT, RBS_BORDERS
 *   - Create structures in WM_NCCREATE
 *   - Additional performance enhancements.
 *
 * rev 8
 *  1. Create array of start and end band indexes by row and use.
 *  2. Fix problem with REBAR_Layout Phase 2b to process only if only
 *     band in row.
 *  3. Set the Caption Font (Regular) as default font for text.
 *  4. Delete font handle on control distruction.
 *  5. Add UpdateWindow call in _MoveChildWindows to match repainting done
 *     by native control
 *  6. Improve some traces.
 *  7. Invalidate window rectangles after SetBandInfo, InsertBand, ShowBand
 *     so that repainting is correct.
 *  8. Implement RB_MAXIMIZEBAND for the "ideal=TRUE" case.
 *  9. Implement item custom draw notifications partially. Only done for 
 *     ITEMPREPAINT and ITEMPOSTPAINT. (Used by IE4 for "Favorites" frame
 *     to draw the word "Favorites").
 * rev 8a
 * 10. Handle CCS_NODIVIDER and fix WS_BORDER code.
 * 11. Fix logic error in _AdjustBands where flag was set to valid band
 *     number (0) to indicate *no* band.
 * 12. Fix CCS_VERT errors in _ForceResize, _NCCalcSize, and _NCPaint.
 * 13. Support some special cases of CCS_TOP (and therefore CCS_LEFT),
 *     CCS_BOTTOM (and therefore CCS_RIGHT) and CCS_NOPARENTALIGN. Not 
 *     at all sure whether this is all cases.
 * 14. Handle returned value for the RBN_CHILDSIZE notify.
 * 15. Implement RBBS_CHILDEDGE, and set each bands "offChild" at _Layout
 *     time.
 * 16. Fix REBARSPACE. It should depend on CCS_NODIVIDER.
 * rev 8b
 * 17. Fix determination of whether Gripper is needed in _ValidateBand.
 * 18. Fix _AdjustBand processing of RBBS_FIXEDSIZE.
 *
 *
 *    Still to do:
 *  2. Following still not handled: RBBS_FIXEDBMP,
 *            RBBS_USECHEVRON, CCS_NORESIZE,
 *            CCS_NOMOVEX, CCS_NOMOVEY
 *  3. Following are only partially handled: 
 *            RBS_AUTOSIZE, RBBS_VARIABLEHEIGHT
 *  5. Native uses (on each draw!!) SM_CYBORDER (or SM_CXBORDER for CCS_VERT)
 *     to set the size of the separator width (the value SEP_WIDTH_SIZE 
 *     in here). Should be fixed!!
 *  6. The following messages are not implemented:
 *        RB_BEGINDRAG, RB_DRAGMOVE, RB_ENDDRAG, RB_GETCOLORSCHEME,
 *        RB_GETDROPTARGET, RB_MAXIMIZEBAND,
 *        RB_SETCOLORSCHEME, RB_SETPALETTE, RB_SETTOOLTIPS
 *        WM_CHARTOITEM, WM_LBUTTONDBLCLK, WM_MEASUREITEM,
 *        WM_PALETTECHANGED, WM_PRINTCLIENT, WM_QUERYNEWPALETTE,
 *        WM_RBUTTONDOWN, WM_RBUTTONUP,
 *        WM_SYSCOLORCHANGE, WM_VKEYTOITEM, WM_WININICHANGE
 *  7. The following notifications are not implemented:
 *        NM_CUSTOMDRAW, NM_RELEASEDCAPTURE
 *        RB_CHEVRONPUSHED, RBN_MINMAX
