33 The image that it manipulates will be grabbed from the
34 portion of the screen underlying the window, or from the
35 system's video input, or from a random file on disk, as
36 indicated by the ''grabDesktopImages'',
37 ''grabVideoFrames'', and ''chooseRandomImages''
38 options in the ''~/.xscreensaver'' file; see
