# Test case for line far outside a small region.  First point
# is > 180 points away so is seen as -179 away while second is
# +179 away. The projected x coordinates are thus far outside
# on either side, tricking the rect_clip function to compute
# two crossings and drawing the line.  Added new check to try
# to avoid this case - monitoring to see if it is OK; see
# gmt_map.c's gmt_rect_overlap function. P. Wessel 7/31/2014
# There should be no lines crossing these two maps.
