 * NOTES
 *   PLEASE don't try to improve or change this code right now. Many
 *   features are still missing, but I'm working on it. I want to avoid
 *   any confusion. This note will be removed as soon as most of the
 *   features are implemented.
 *     Eric <ekohl@abo.rhein-zeitung.de>
 *
 * TODO:
 *   - Bitmap drawing.
 *   - Button wrapping.
 *   - Messages.
 *   - Notifications.
 *   - Fix TB_GETBITMAPFLAGS.
 *   - Fix TB_GETROWS and TB_SETROWS.
 *   - Tooltip support (partially).
 *   - Unicode suppport.
 *   - Internal COMMCTL32 bitmaps.
 *   - Fix TOOLBAR_Customize. (Customize dialog.)
 *
 * 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.
