Okay, so what about GST_TAG_GPS_LATITUDE, GST_TAG_GPS_LONGITUDE,
GST_TAG_GPS_ALTITUDE as doubles

GST_TAG_GPS_LATITUDE: degrees, negative values for southern latitudes
GST_TAG_GPS_LONGITUDE: degrees, negative values for western longitudes
GST_TAG_GPS_ALTITUD: meters, zero is sea level

That matches what 3gp/mp4 does. Its also sufficient for EXIF [1][2]

Instead of GST_TAG_GPS_AREAINFORMATION we could have GST_TAG_GPS_LOCATION (see
Bug #548652). I would be fine with assuming that we talk about Earth locations
always for now.
