command line utility which draws images on terminals

 Ueberzug is a command line utility which draws images on terminals
 using child windows.
 .
 It has several advantages over w3mimgdisplay:
 .
  - no race conditions, as a new window is created to display images
  - expose events will be processed, so images will be redrawn on
    switched workspaces
  - tmux support (excluding multi pane windows)
  - terminals without the WINDOWID environment variable are supported
  - chars are used as both the position and size unit
  - no memory leak (and unlimited cache)
