OK, I got things working, but I have another question.
First off, to get things to work, I had to rebuild SimGear
--with-jpeg-factory and then reconfigure and rebuild FlightGear. The
configure process actually checked for jpeg, so when it is not available it
gives an error even though the help say

Just two quick questions. What effect do gauges have on the frame rates of
virtual cockpits. i.e. is there as strong effect after 10 or 20 gauges?
Also is it possible to configure the views so that a virtual cockpit is only
visible when actually in the cockpit?

Hi Mathias,
this reminds me that I had implemented the attached cleanup-patch for
SGLocation (as part of the abstract terrain API). I currently don't have the
time to finish the API, so the patch is a bit out of context (requires some
small changes in flightgear), but if you are currently workin

Excellent. This bug has been annoying me for a long, long time.

Hi,
I have done a patch to eliminate the jitter of 3D-objects near the viewpoint
(for example 3D cockpit objects).
The problem is the roundoff accuracy of the float values used in the
scenegraph together with the transforms of the eyepoint relative to the
scenery center.
The solution will be

Yep, they also could win the European Rugby Championship ;-)

I'm sure it takes much less to get champagne flowing in Toulouse ;-)
