Also, how do I put a border around the map projection/image?
And, when the image shows up in the display window, it
has this little selection thingy around it that apparently
lets me rotate (I'm not even going to ask why ROTATE
would be the default here!) the image about. How can I
get rid of this selection thing-ama-jig?
Cheers,
