* Added a "Set as desktop background" option with an easy to use engine based
on the OpenTracker's BackgroundImage implementation. * It's currently placed in the "View" menu, even though it doesn't fit that good, I think it should definitely be part of the right click menu. * Some more cleanup. git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@16273 a95241bf-73f2-0310-859d-f6bbb57e9c96
