- * 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
