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

SYNOPSIS
       mirrorblob  [-display  host:display.screen]  [-visual visual] [-window]
       [-root] [-wire] [-delay number] [-fog]  [-walls]	 [-colour]  [-texture]
       [-offset-texture]  [-blend]  [-antialias]  [-resolution number] [-bumps
       number] [-fade-time number] [-hold-time number] [-zoom number] [-fps]

DESCRIPTION
       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.

OPTIONS
       -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.

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

       -root   Draw on the root	window.	 -wire Render in wireframe instead  of
	       solid.

       -delay number
	       Per-frame  delay,  in  microseconds.  Default: 10000 (0.01 sec-
	       onds.).

       -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.

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

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

       -hold-time number
	       Time until loading a new	image.

       -fade-time number
	       Time taken to transition	between	images.

       -zoom number
	       Size multiplier for blob.

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

ENVIRONMENT
       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.
