       The slidescreen program takes an image, divides it into a grid, deletes a random square of that grid, and
       then randomly slides one of the neighbors of this "hole" into the hole (and repeat.)

       The  image  that  it manipulates will be grabbed from the portion of the screen underlying the window, or
       from the system's video input, or from a random file on disk,  as  indicated  by  the  grabDesktopImages,
       grabVideoFrames, and chooseRandomImages options in the ~/.xscreensaver file; see xscreensaver-settings(1)
       for more details.

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.

slidescreen accepts the following options:

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

       --root  Draw on the root window.

       --window-idnumber
               Draw on the specified window.

       --install
               Install a private colormap for the window.

       --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.

       --grid-sizepixels
               The size of the grid cells.  Default 70 pixels.

       --ibwpixels
               The size of the "gutter" between grid cells.  Default 4 pixel.

       --incrementpixels
               How many pixels by which a piece should be moved when sliding to  a  new  location.   Default  10
               pixels.

       --delaymicroseconds
               How  much  of  a  delay should be introduced between steps of the animation of the motion of each
               segment.  Default 50000, which is 0.05 seconds.  This  is  closely  related  to  the  --increment
               parameter.

       --delay2microseconds
               How  much  of  a  delay should be introduced between the end of the motion of one segment and the
               beginning of the motion of another.  Default 1000000, which is one second.

       --durationseconds
               How long to run before loading a new image.  Default 120 seconds.

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