-
-LayoutManager is a convenient abstraction that separates messy layout heuristics
-from the other particulars of a Window.

-A LayoutManager implementation attached to an Aura Window can control the layout
-(bounds, transform, and even other properties) of that Window's children.
-
-A LayoutManager is typically attached to a window at creation/initialization
-time. It is notified when:
-
-*   a child window added or removed, or the visibility of a child
-            changes. This type of event may cause other child windows to be
-            re-laid out.
-*   the size of the bound Window changes, which may cause the children
-            to be re-laid out to accommodate the new viewport size.
-
-A LayoutManager implementation can be used for everything from simple behavior
-like keeping the application launcher docked to the bottom of the screen to
-complex layout heuristics for multiple windows across several virtual
-workspaces.
