IFSPLOT is a program to generate Iterated Function System (IFS)
fractals, in plane. The user must supply, to stdin, the affine
transformations that define the IFS. Each transformation has the form

(1)	w(x,y) = (ax + by + e, cx + dy + f),

that is specified by a lines

  a b c d e f p

where the six first constants state for the transformation parameters
as in (1). The last quantity, p, is a transformation probability.
For example, the IFS that defines the Classical Sierpinski is

 0.5 0 0 0.5 0 0 0.33
 0.5 0 0 0.5 0 1 0.33
 0.5 0 0 0.5 1 0 0.34

If these transformations are stored on a file, for example called 
sierpinski.ifs, to run the program do

    ifsplot < sierpinski.ifs

For further information about IFS fractals, please read the book of
Michael Barnsley, "Fractals Everywhere", 2nd ed., Academic Press,
2000.
