%DRAW FRACTAL
%
%   The DRAW FRACTAL control panel is used to instigate
%the creation of the fractal images defined by all of
%the existing functions currently labeled as "on" (see
%FCN SELECTION).  The fractal image is drawn in the same
%graphics window where the functions' graphical
%representations appeared.
%   DRAW FRACTAL does just that.  The Control Panel is
%covered, and a progress bar appears which indicates the
%progress of the algorithm.
%   The ITERATIONS editable text box allows the user to
%determine the number of points plotted (iterations
%of the random fractal-drawing algorthim) in the fractal.
%In the default window size of 535x560 pixels (see
%GRAPHICS WINDOW), about 5000 iterations are needed to get
%a good idea of what the fractal will look like, and
%10,000 (the default setting) are usually sufficient to
%generate a robust and pleasing image (multiple small-scale
%functions may require more iterations for a robust image).
%The user will want to experiment and find a number which
%represents a balance between speed (a function of the
%particulal computer) and image quality.  The default value
%of 10,000 may be changed by altering the value on line
%59 of the program "fracctl.m".
%   The HOLD FUNCTION BOXES check box, when on, holds the
%functions' graphical representations on the screen when
%the fractal is drawn.  Although this clutters the resuling
%images, it does show clearly how each function makes its
%own smaller copy of the fractal.
