       The ifs program draws spinning, colliding iterated-function-system images.

DISPLAY to get the default host and display number.

       XENVIRONMENT
               to  get  the  name  of  a  resource  file  that  overrides  the  global  resources  stored in the
               RESOURCE_MANAGER property.

       XSCREENSAVER_WINDOW
               The window ID to use with --root.

       ifs - draws spinning, colliding iterated-function-system images

--visualvisual
               Specify  which  visual  to  use.   Legal  values are the name of a visual class, or the id number
               (decimal or hex) of a specific visual.

       --window
               Draw on a newly-created window.  This is the default.

       --root  Draw on the root window.

       --window-idnumber
               Draw on the specified window.

       --no-db Disable double-buffering.

       --delaynumber
               Per-frame delay, in microseconds.  Default: 20000

       --colorsnumber
               Number of colours to use. Default: 200

       --detailnumber
               In --iterate mode, number of times to randomly iterate the functions, in thousands.  In --recurse
               mode, number of times to apply functions (recursion depth) before drawing each point.  Default: 9

       --functionsnumber
               Number of functions to be iterated. Default: 3

       --iterate
               Calculate by iteratively applying the functions in a random order, usually faster than --recurse.
               This is the default.

       --recurse
               Calculate by recursively applying all combinations of the  functions.   This  is  the  historical
               behavior and may produce neater output than --iterate.

       --no-rotate
               Disable the rotation component of the functions.

       --no-scale
               Disable the scaling component of the functions.

       --no-translate
               Disable the varying translation component of the functions.

       --no-multi
               Turn off multi-coloured mode, only one colour is used to colour the whole set.

       --fps   Display the current frame rate and CPU load.
