FLOATING POINT MANDELBROT.
Its good with an FPA10 or 11 otherwise get a big packet of
biscuits and a thermos.
The size is in multiples of 32*25.6 pixels so a size of 1
gives a 32*25 image and 10 gives a 320*256 image.
Number of iterations is the number of iterations and can
range from 1 to boredom (65535 is a good place to stop, cos
the colourmap isnt defined after that and any Zeroes in the
colour map will cause the programs adaptive filling routine
to hang)
Use the left&right mouse buttons to change the size of the
zoombox
Middle button draws the image
SpaceBar saves the current image in directory MANDSAVE$DIR
(set up in the !run file). It will not overwrite previously
saved images.
Other things you can do
change the D suffix to E suffix in the floating point directives
to get stupid resolution.
Make it work in mode21 or even on 1280*1024 on the RPC
Have fun

PS after making new colour maps:
run the make map program, this copies the colour map and stretches it
so that close to the set doesnt look like white noise. Try a
courseness of around 10000-1000000 or so, in general the bigger the
better, as usual.
