*
* This code was audited for completeness against the documented features
* of Comctl32.dll version 6.0 on Oct. 3, 2004, by Dimitrie O. Paun.
*
* 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
* - BS_NOTIFY: is it complete?
* - BS_RIGHTBUTTON: same as BS_LEFTTEXT
*
* Messages
* - WM_CHAR: Checks a (manual or automatic) check box on '+' or '=', clears it on '-' key.
* - WM_SETFOCUS: For (manual or automatic) radio buttons, send the parent window BN_CLICKED
* - WM_NCCREATE: Turns any BS_OWNERDRAW button into a BS_PUSHBUTTON button.
* - WM_SYSKEYUP
* - BCM_GETIDEALSIZE
* - BCM_GETIMAGELIST
* - BCM_GETTEXTMARGIN
* - BCM_SETIMAGELIST
* - BCM_SETTEXTMARGIN
