       Draws a wobbling blob, making use of alpha blending, fog, textures, and lighting,  plus  a  ``frames  per
       second'' meter so that you can tell how fast your graphics card is... Requires OpenGL.

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.

       mirrorblob - Draws a wobbly blob that distorts the image behind it.

--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.  --wire Render in wireframe instead of solid.

       --delaynumber
               Per-frame delay, in microseconds.  Default: 10000 (0.01 seconds.).

       --fog|--no-fog
               Whether to enable fog.

       --walls|--no-walls
               Add walls for blob to hit.

       --colour|--no-colour
               Draw coloured blob.  If also textured, the texture will have color mixed in.

       --texture|--no-texture
               Whether to wrap a texture image on the blob.

       --offset_texture|--no-offset_texture
               Whether to ofset the texture calculations to only use a region of the image
                under the blob.  This works well with a semi-transparent blob.

       --blend|--no-blend
               Whether to draw a transparent blob. (see also offset_texture above)

       --antialias|--no-antialias
               Whether to antialias lines.

       --resolutionnumber
               Resolution of the tessellation used to calculate and draw the blob.  Larger
                numbers give a smoother blob but increase calculation times exponentially.

       --bumpsnumber
               Number of bumps used to distort the blob.

       --hold-timenumber
               Time until loading a new image.

       --fade-timenumber
               Time taken to transition between images.

       --zoomnumber
               Size multiplier for blob.

       --fps   Display the current frame rate, CPU load, and polygon count.
