Subject: Bug 1232 - NEWT Translucent Decorated Windows Not Working On Windows
 >= 8 (Lack of Aero / Blur )

Adopting new undocumented user32.dll Windows >= 8 API:
  - SetWindowCompositionAttribute / AccentState

See:
  - <https://github.com/riverar/sample-win10-aeroglass/blob/master/MainWindow.xaml.cs>
  - <http://withinrafael.com/adding-the-aero-glass-blur-to-your-windows-10-apps/>
  - <http://undoc.airesoft.co.uk/user32.dll/SetWindowCompositionAttribute.php>
  - <http://undoc.airesoft.co.uk/user32.dll/GetWindowCompositionAttribute.php>

+++

Cleaning up WindowsDWM.h, use on header file (in stub_includes)
for GlueGen and implementation.

+++

Merge java implementation within GDIUtil.DwmSetupTranslucency(..),
to be utilized by NEWT and JOGL.

NEWT issues GDIUtil.DwmSetupTranslucency(..) at creation
and when toggling decoration.

Toggling decoration on Win >= 8 leads to lost of translucency
when returning to decorated window.
On Win 7, this may work .. but is also buggy.

+++

Followup patch is needed for NEWT to _not_ clear the background!
