       gflux - rippling surface graphics hack

       gflux [-display host:display.screen] [-window] [-root] [-install] [-visual visual] [-delay
       microseconds] [-fps] [-squares num] [-resolution num] [-mode  mode]  [-flat  num]  [-speed
       num]  [-rotationx  num]	[-rotationy  num] [-rotationz num] [-waves num] [-waveChange num]
       [-waveHeight num] [-waveFreq num] [-zoom num]

       The gflux program draws a colourfull animated rippling square rotating in 3D space.

       gflux 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 visual.

       -squares num
	       Specifies the size of the grid in squares. default 19

       -resolution num
	       Specifies the wireframe detail of the squares. default 4

       -mode mode
	       Specifies  the  draw  method:  wireframe; solid (meaning a solid colored surface);
	       light (same as solid,  but  with  lighting  effects);  checker  (a  texture-mapped
	       checkerboard pattern); or grab (meaning grab an image to manipulate.)

	       When  grabbing  images,	the  image 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 chooseRandomIm-
	       ages options in	the  ~/.xscreensaver  file;  see  xscreensaver-demo(1)	for  more

       -flat num
	       0 for smooth shading 1 for flat. default 0

       -speed num
	       Specifies speed of ripples flowing over the surface. default 0.05

       -rotationx num -rotationy num -rotationz num
	       Specifies the speed of rotation of the surface in these axis

       -waves num
	       Specifies  the number of ripple centres at any one time.  Values should be greater
	       than 1.	default 3

       -waveChange num
	       Specifies the duration of a ripple centre.  after this they fade away to be reborn
	       elsewhere with a different frequency. default 50

       -waveHeight num
	       Specifies the height of ripples on the surface. default 1.0

       -waveFreq num
	       Specifies the maximum frequency of ripples. default 3.0

       -zoom num
	       Specifies  the  size of the viewport. Smaller values fill the screen with rippling
	       surface. default 1.0

       -delay microseconds
	       How long to pause between frames.  Default is 20000, or 0.02 second.

       -fps    Display a running tally of how many frames per second are being rendered.  In con-
	       junction 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
