Subclass of Group that compensates for a multi-monitor defect in the JavaFX 1.0 release (RT-2835). This class is only needed if you are using the cache attribute and expect Nodes to be dragged between monitors. There may be a small performance hit due to the binds on the size and position of this Group.
Usage: Simple replace Group with this class instead.
Once issue RT-2835 is fixed, this class will be immediately deprecated.
