Subject: [PATCH] From Wojciech Lewandowski, "Most recent changes to
 CameraPathEventHandler change path writing method. Now control points are
 written on the fly. But default stream precision is not adjusted as it used
 to and remains set to 6 digits (at least with VS 2008) so larger coordinates
 like positions on Earth Ellipsoid loose lots of fidelity. This patch fixes
 this issue. "
