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."
