From Stephan Huber, "New features:
+ Multi-display-support + automatic hiding of the menubar/dock if one of the windows intersects the menubar/dock Bugfixes: + event-handling was done by the first opened window, other windows did not receive events -- fixed + mouse-coordinates were absolute, now they are relative to the window. known bugs: + windows with decoration and in fullscreen-size are moved by the system a little bit, so that the titlebar is accessible/visible. So if you want real fullscreen-windows, don't decorate the window :) I updated the XCode-project-file so all ported examples are linked against osgViewer."
