This is a known problem with the GFS grids (see:
http://my.unidata.ucar.edu/content/software/idv/docs/userguide/Bugs.html#faq1_cat3_11
since they are on a latitude/longitude native grid. The problem is
that we don't take into account the variation of longitude in the
y direction. I hope to be able to fix that by the next release.
