+Author: Jasper St. Pierre <jstpierre@mecheye.net>
+Date:   Thu Nov 7 17:14:47 2013 -0500
+
+    layout: Fix several issues with the background management code
+    
+    If monitor-changed fires at startup, it will destroy all of the
+    backgrounds, but since this._isStartup is true, won't recreate any
+    of them. Additionally, since _bgManagers is indexed by monitor index,
+    if the primary index is not 0, it could become a sparse array (e.g.
+    [undefined, undefined, primaryBackground]), and our for loop will
+    crash trying to access properties of undefined.
+    
+    Fix both of these issues by always creating background managers for
+    every monitor, hiding them on startup but only showing them after
+    the startup animation is complete.
+    
+    One thing we need to watch out for is that while LayoutManager is
+    constructing, Main.uiGroup / Main.layoutManager will be undefined,
+    so addBackgroundMenu will fail. Fix this by passing down the uiGroup
+    to the background menu code.
+
