Ignoring 0/0 Coordinates

[dret]

I have been using this for many years and it is still working! I am amazed, and thanks a lot! One issue I have encountered is that some of my GPX files seem to have 0/0 entries in there, probably in cases when the satellite signal was lost. It would be useful to ignore these points, as the likelihood of these being "real" waypoints is very slim.
