> +++ This bug was initially created as a clone of Bug #515502 +++
> Tutorial: Writing High-DPI Win32 Applications
> https://msdn.microsoft.com/en-us/library/windows/desktop/dd464659%28v=vs.85%29.aspx
> As per above MSDN there is a event notification 'WM_DPICHANGED' sent to applications with SetProcessDpiAwareness set to 'PROCESS_PER_MONITOR_DPI_AWARE'.
> SWT needs above mechanism to be in place, to start receive the DPI change notification from OS and then re-layout accordingly.
