 /**
-A Root is a special type of Panel that covers and entire Window and accepts
-input from it.  When created, a Root widget will take its size from the window
-it is created for.  The size can be changed, but a Root should always be
-rendered to fill the window in order to get coordinates mapped correctly.
+A Root is a special type of Panel that covers the entire viewport and receives
+input from keyboard and mouse.  It can be used by itself or in a GL::Pipeline.
+Due to its specialized nature it's recommended to not use it with Scenes or
+other containers.
