I have not tested my patch with snappy GPX nodes in any way. I don't
need them and I don't like them. I draw everything myself, taking the
GPX display as a hint. This would need to be sorted out should this
patch be used.

Right, the preference code would need to be added. This is only a
preview-quality patch so everybody can see/test what I'm talking about.
