/**
 * meta_workspace_activate_with_focus:
 * @workspace: a #MetaWorkspace
 * @focus_this: the #MetaWindow to be focused, or %NULL
 * @timestamp: timestamp for @focus_this
 *
 * Switches to @workspace and possibly activates the window @focus_this.
 *
 * The window @focus_this is activated by calling meta_window_activate()
 * which will unminimize it and transient parents, raise it and give it
 * the focus.
 *
 * If a window is currently being moved by the user, it will be
 * moved to @workspace.
 *
 * The advantage of calling this function instead of meta_workspace_activate()
 * followed by meta_window_activate() is that it happens as a unit, so
 * no other window gets focused first before @focus_this.
