* @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.
