I think this is "caused" by your extremly
small zooming angle (i.e.: angle 0.00004)
Have you tried with larger viewing angles ?
Try to uncomment the different camera angle
statements in the code below.
(The coasts looks ok for me at the 3 given
magnifications when I do this.)
(Btw.: This is my first post to this group :)
