6395346 : Need to make Java process High-DPI-aware on Windows Vista
added a call to SetProcessDPIAware()

Because of the inherent race conditions in relying on API, Windows 7
allows the same to be specified in the manifest <dpiAware>true</dpiAware>.

See the Writing DPI-Aware Win32 Applications white paper at
http://go.microsoft.com/fwlink/?LinkID=129586 which has this example :

<assembly xmlns="urn:schemas-microsoft-com:asm.v1" manifestVersion="1.0" xmlns:asmv3="urn:schemas-microsoft-com:asm.v3" >
     <asmv3:application>
            <asmv3:windowsSettings xmlns="http://schemas.microsoft.com/SMI/2005/WindowsSettings">
                  <dpiAware>true</dpiAware>
           </asmv3:windowsSettings>
     </asmv3:application>
</assembly>

We should update src/windows/resource/template.manifest with this.
