Hi,
I created points to draw lines, and I would like to know how do to manage
to choose the display order to superimpose lines with different widths and
colors. 

Thanks, and sorry for my bad English, i am French...

KML itself has no such concept unfortunately, hence libkml has no control
to offer for it.  This is a known enhancement request for the KML language
itself (and its implementation in Google Earth and Google Maps).

One trick that has been employed is to use very slightly different altitudes
to indicate that one geometric object should be drawn "on top of" another,
but there's no guarantee for this behavior as it is unspecified.  Also, 
strictly speaking
altitudinal stacking is not the same as draw order.
