Removed unnecessary 'offset' added to quad graph. This code could cause the position of the

karts to be incorrect just after crossing the lap line. Problem was that the center point
of the first quad line (which by definition is on the line) would be considered to be not
on the line due to floating point errors (i.e. 0.5*(A+B) would not be on the line between
A and B).
