[Xastir-dev] Excellent catch!

[Curt, WE7U]

Looks like I messed up the map_visible_lat_lon() function a while
back.  Gerry Steuve just corrected it.

It sure is easy to get mixed up with the different coordinate
systems we use for mapping...  I had to draw a diagram in order to
recheck the logic.  I added that diagram to the comments for that
function so perhaps I won't mess it up again.  Not in the same way
anyway.

Thank you for fixing that!
