   * 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)

  * 		TOOLBAR_MeasureButton
  *
  * Calculates the width and height required for a button. Used in
  * TOOLBAR_CalcToolbar to set the all-button width and height and also for
  * the width of buttons that are autosized.
  *
  * Note that it would have been rather elegant to use one piece of code for
  * both the laying out of the toolbar and for controlling where button parts
  * are drawn, but the native control has inconsistencies between the two that
  * prevent this from being effectively. These inconsistencies can be seen as
  * artefacts where parts of the button appear outside of the bounding button
  * rectangle.
  *
  * There are several cases for the calculation of the button dimensions and
  * button part positioning:
