* Use "const string&" rather than "string" in function calls when appropriate. * Use "const Point3D&" instead of "Pint3D" in function calls when appropriate. * Improved course calculation in calc_gc_course_dist() * Safer thread handling code. Vassilii Khachaturov: Dont use "const Point3D&" for return types unless you're absolutely sure. Erik Hofman: * Use SGD_(2)PI(_[24]) as defined in simgear/constants.h rather than calculating it by hand every time.

// ATCdisplay.hxx - class to manage the graphical display of ATC messages.
