 * NOTES
 *
 * This code was audited for completeness against the documented features
 * of Comctl32.dll version 6.0 on Mar. 14, 2004, by Robert Shearman.
 * 
 * Unless otherwise noted, we believe this code to be complete, as per
 * the specification mentioned above.
 * If you discover missing features or bugs please note them below.
 * 
 * TODO:
 *   - Styles:
 *     - TBSTYLE_REGISTERDROP
 *     - TBSTYLE_EX_DOUBLEBUFFER
 *   - Messages:
 *     - TB_GETMETRICS
 *     - TB_GETOBJECT
 *     - TB_INSERTMARKHITTEST
 *     - TB_SAVERESTORE
 *     - TB_SETMETRICS
 *     - WM_WININICHANGE
 *   - Notifications:
 *     - NM_CHAR
 *     - TBN_GETOBJECT
 *     - TBN_SAVE
 *   - Button wrapping (under construction).
 *   - Fix TB_SETROWS and Separators.
 *   - iListGap custom draw support.
 *
 * Testing:
 *   - Run tests using Waite Group Windows95 API Bible Volume 2.
 *     The second cdrom contains executables addstr.exe, btncount.exe,
 *     btnstate.exe, butstrsz.exe, chkbtn.exe, chngbmp.exe, customiz.exe,
 *     enablebtn.exe, getbmp.exe, getbtn.exe, getflags.exe, hidebtn.exe,
 *     indetbtn.exe, insbtn.exe, pressbtn.exe, setbtnsz.exe, setcmdid.exe,
 *     setparnt.exe, setrows.exe, toolwnd.exe.
 *   - Microsoft's controlspy examples.
 *   - Charles Petzold's 'Programming Windows': gadgets.exe
 *
 *  Differences between MSDN and actual native control operation:
 *   1. MSDN says: "TBSTYLE_LIST: Creates a flat toolbar with button text
 *                  to the right of the bitmap. Otherwise, this style is
 *                  identical to TBSTYLE_FLAT."
 *      As implemented by both v4.71 and v5.80 of the native COMCTL32.DLL
 *      you can create a TBSTYLE_LIST without TBSTYLE_FLAT and the result
 *      is non-flat non-transparent buttons. Therefore TBSTYLE_LIST does
 *      *not* imply TBSTYLE_FLAT as documented.  (GA 8/2001)
