// [IP] This trick (handling WM_ENABLE) allows to skip using COLOR_GRAYTEXT for disabled control background (default Win32)
// You can now handle the WM_CTLCOLOR/CTL_COLOREDIT message in the parent or the reflected (=WM_CTLCOLOR) message in the
// derived subclass as you normally would. And you can still use IsWindowEnabled should you care to.
