 * NOTES
 *
 *  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)
 *
 * 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.
