MCI_OVLY_RECT_PARMS
 
        The MCI_OVLY_RECT_PARMS structure contains parameters for the
        MCI_PUT and MCI_WHERE messages for video overlay devices. When
        assigning data to the fields in this data structure, set the
        corresponding MCI flags in the dwFlags parameter of
        mciSendCommand to validate the fields.
 
        typedef struct {
            DWORD dwCallback;
            RECT rc;
        } MCI_OVLY_RECT_PARMS;
