PTH VERSION 0 - Path files for Live for Speed S2
=============


The nodes are given by a fixed point position (X, Y, Z) and a
floating point direction (X, Y, Z)

The node can be considered as a line perpendicular to its direction.

Outer and driving area left and right limits are given.


TYPES :
=======

1) X,Y,Z int : 32-bit fixed point world coordinates (1 metre = 65536)

X and Y are ground coordinates, Z is up.

2) float : 32 bit floating point number
