It's not.  I wrote a postscript program to create the same image in vector
form as it appears in raster form, but I didn't "include" the raster image
in the postscript program in any way.

That's what mine does, but it also does some simple 3D shading (to make a
colored sphere) and some other graphics tricks.  Not efficient, but it
works.  What it doesn't do is include a raster image (which in Postscript
is a huge section of pixel data using - I think - an "image" construct).

I don't know how to do that yet.  I didn't dig that deep.  In fact, I tried
to figure out how to include a raster image into a Postscript program but
the book I had didn't have a very good example of that, so I just punted
and redrew the graphics using postscript code.

I'll send the postscript program in a separate, direct email.
