This number, between 0 and 1, determines the minimum fraction of 
the destination points to be colored by the IFS algorthm. The 
remainder simply use the nearest available pixel to determine 
the colour. Values very close to 1 will produce better looking 
images, but will take longer. A default of 0.999999 is used
if not specified.

=item max_factor

This number, greater than 1, determines the maximum number
of iterations that the IFS algorithm uses. A value of 1
will have this iteration number equal to the number of
pixels in the destination; increasing this value will
produce better looking images, but at the expense of speed.
Reasonable values are around 5-10. A default of 7 is used
if not specified.

=back

The default values of C<min_factor> and C<max_factor> will
be used if these are not passed to C<copyIFS>, but if you

Reasonable values are around 5.
