Floating windows will require some modification to the Leaf struct. Mainly a new field of type *xrect.XRect. This new field will indicate that this leaf has a user defined position/size. A new method will be added to the Node specification called Floating() if this method returns true, then that Node's Layout method will be called with the XRect passed to its parent's Layout function and space will not be allocated for it. Then that Node's Layout method will be responsible for positioning itself if, it has a user defined pos/size, it will place itself to that. otherwise, it will center itself according to the XRect passed to it.
