 *  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)
 *
 *
 * TODO:
 *   - A little bug in TOOLBAR_DrawMasked()
 *   - Button wrapping (under construction).
 *   - Messages.
 *   - Notifications (under construction).
 *   - Fix TB_SETROWS.
 *   - Tooltip support (almost complete).
 *   - Unicode suppport (under construction).
 *   - Fix TOOLBAR_SetButtonInfo32A/W.
 *   - TBSTYLE_AUTOSIZE for toolbar and buttons.
 *   - I_IMAGECALLBACK support.
 *   - iString of -1 is undocumented
 *   - Customization dialog:
 *      - Add flat look.
 *      - Minor buglet in 'available buttons' list:
 *        Buttons are not listed in M$-like order. M$ seems to use a single
 *        internal list to store the button information of both listboxes.
 *      - Drag list support.
 *      - Help and Reset button 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,
