Description Sven Gothel 2011-09-03 03:32:59 CEST

Translucent windows (or drawables) are a nice to have feature
allowing users to create non rectangular shaped things on the desktop
and a more seamless integration w/ the desktop.

This is possible using compositing window manager like
Windows 7/Vista Aero, X11 XRender/OpenGL KDE, Gnome, etc ..

Initial X11/GLX support is commited:
  dcb0cc571298be90d0db7ad00fef835fe5fdc46d

  2f12b219988dd28b1b2c191afc94b7704022a84a
 
Also the little changes to the 'core' code:
  bbdd6f95687da343bf7a6550c3bc9bb4444116e5

Translucency is triggered just using the Capabilities:
  caps.setBackgroundOpaque(false);

TODO: Windows and OSX .. maybe Android

It seems translucency doesn't work on Windows 8 nor Windows 10 (they removed Aero effect in Windows 8 AFAIK). Tried with NEWT.
