21 * NOTES
22 *
23 * This code was audited for completeness against the documented features
24 * of Comctl32.dll version 6.0 on Oct. 3, 2004, by Dimitrie O. Paun.

32 * - BS_NOTIFY: is it complete?
33 * - BS_RIGHTBUTTON: same as BS_LEFTTEXT
34 *
35 * Messages
36 * - WM_CHAR: Checks a (manual or automatic) check box on '+' or '=', clears it on '-' key.
37 * - WM_SETFOCUS: For (manual or automatic) radio buttons, send the parent window BN_CLICKED
38 * - WM_NCCREATE: Turns any BS_OWNERDRAW button into a BS_PUSHBUTTON button.
