[Xastir-checkins] CVS: xastir/src db.c,1.298,1.299

[Curt M. <we...@us...>]

Update of /cvsroot/xastir/xastir/src
In directory sc8-pr-cvs1.sourceforge.net:/tmp/cvs-serv1623

Modified Files:
	db.c 
Log Message:
Changing the distance at which Xastir will skip a track segment, from >1
degree lat/long to >2 degrees.  Any track segment less than 2 degrees in
N/S and E/W length will get drawn, as long as the time between posits is
less than 45 minutes.  If over 45 minutes, the segment gets skipped as
well.
