MandelSearch

This program is designed to be run on a SUN
workstation under X Windows (Open Windows). It
has not been ported elsewhere.

The program imager uses the file `params'.  It
allows you to navigate around the Mandelbrot set
and to zoom in on selected portions.

Run the program. Click in the window to start
it.  Click at a selected pixel, and the program
re-starts with the selected region in the center
of the window, zoomed in by a factor of 2. (That
scale factor is the parameter scale_mod.) On a
slow system - e.g., one without floating point
hardware - be patient. The mouse click is
detected ever 1% of the window painting. That is
also when the sliding indicator is updated at the
top of the screen.

The window size parameters are given by init_wide
and init_tall.

The parameter ripples selects the zebra pattern
for the M set's complement.

Many of the program's global variables are
parameterized by declaring them in
`defaultparams' and giving them default values
therein. Those defaults are overridden by
`params' at run-time. When you change
defaultparams, you must re-make.

Because of the program's development history, it is
not real clean. Some parameters are left over from 
previous programs. Sorry.
