+terminals by using child windows.  The advantages of using Überzug are:
+@itemize
+@item No race conditions as a new window is created to display images.
+@item Expose events will be processed, so images will be redrawn on switch
+workspaces.
+@item Tmux support (excluding multi pane windows).
+@item Terminals without the WINDOWID environment variable are supported.
+@item Chars are used as position - and size unit.
+@item No memory leak (/ unlimited cache).
