Comment(by hamish):

 if the raster library can handle this situation automatically and cleanly
 for both the 0-360 and -180-180 cases, then why can't the vector lib be
 taught do the same? forcing the user to manually do a task which should be
 figured out automagically by the software seems less than ideal.

 is the real problem not actually the literal numbers stored in the data
 file, but rather a failure of the vector modules and display modules to
 wrap LL when needed, or the vector reading library functions for not
 automatically cleansing to within range?

 (aka get rid of any unqualified Pythagorean shortcuts in the code, and
 have libraries swap over geodesic calculations if a LL location is
 detected)
