The idea of chaning TrackPoint to GPS_point, which will be derived from QGeoCoordinate AND discard all the drawing code its proving to be good. Also this is a good apportunity to stop using QPointF to store lat/lon, due to the annoying limit of using single precision on ARM which leads to serious precision limits.
So far so good... stay tuned!
RIght now i am investigating if using GPSBabel for GPX read/write is a good idea...
