+// Layout represents any graphical layout
+//
+// Lay represents the way to divide space among your childs.
+// It takes a parameter of how much space is available,
+// and returns where exactly to put its childs.
+//
+// Intercept transforms an Env channel to another.
+// This way the Layout can emit its own Events, re-emit previous ones,
+// or even stop an event from propagating, think win.MoScroll.
+// It can be a no-op.
