 Much of it is very in depth, technical and hard to read.  However, near
the end, there are sections such as, "my image is too short" that
explain what parts of the modeline to change to make the image shorter,
taller, wider, narrower, shifted up, shifted down, etc.  Using that I
was able to get a near perfect fit on my screen.
