2547 * The CallWindowProc() function invokes the windows procedure _func_,
2548 * with _hwnd_ as the target window, the message specified by _msg_, and
2549 * the message parameters _wParam_ and _lParam_.
2550 *
2551 * Some kinds of argument conversion may be done, I'm not sure what.
2552 *
2553 * CallWindowProc() may be used for windows subclassing. Use
2554 * SetWindowLong() to set a new windows procedure for windows of the
2555 * subclass, and handle subclassed messages in the new windows
2556 * procedure. The new windows procedure may then use CallWindowProc()
2557 * with _func_ set to the parent class's windows procedure to dispatch
2558 * the message to the superclass.
