        queens - n queens screensaver


        queens  [-display  host:display.screen]  [-window]  [-root]  [-install]
        [-visual visual] [-delay microseconds] [-wireframe] [-fps]


        The queens program solves the n-queens problem (where, in this program,
        N  is  between  5  and  10 queens) using a straightforward backtracking
        algorithm.  The problem is: how may one place N queens on an NxN chess‐
        board such that no queen can attack a sister?


        queens accepts the following options:
        -window Draw on a newly-created window.  This is the default.
        -root   Draw on the root window.
                Install a private colormap for the window.
        -visual visual
                Specify  which  visual  to use.  Legal values are the name of a
                visual class, or the id number (decimal or hex) of  a  specific
                Render  in  wireframe instead of solid.  -fps Display a running
                tally of how many frames per second  are  being  rendered.   In
                conjunction  with  -delay  0, this can be a useful benchmark of
                your GL performance.


        DISPLAY to get the default host and display number.
                to get the name of a resource file that  overrides  the  global
                resources stored in the RESOURCE_MANAGER property.


        It’s not unknown for this and other OpenGL hacks to fail under hardware
        accelaration (UtahGLX) and take the X server with them.  Texture images
        must be 16x16 or 32x32 or 64x64 etc.
