Handling has been improved by changing the way
that lateral and longitudinal forces are combined.
Camber forces are now handled correctly. Cars can
be set to shift to neutral instead of stalling.
Engine torque curves may be specified by a set of
control points. Preliminary support for pit lanes
has been added. Skew calculations have been fixed
and documented.
