+Package layout provides means of partitioning screen space.
+
+A layout exists in a parent Env, and has one or more child Envs. It
+acts as a multiplexer for the children. The parent Env may be a window,
+another layout, or whatever... Several layers of layouts can be composed.
+
+A layout allocates screen area to its children by intercepting Resize
+events from the parent Env. Upon reception by the layout, a Resize event
+is transformed for each child, and forwarded to them.
+
+Draw calls from the children are intercepted and translated onto their
+respective areas before being forwarded to the parent Env.
