False Positive (V2.1)

[Arseniy Masyuk]

Hello,

I think there is a false positive message:

CWE: 571
Condition 'alpha>=1' is always true

on the following code:

i2d::CVector2d CLine2d::GetNearestPoint(const i2d::CVector2d& point) const
{
double alpha = GetCastAlpha(point);

if (alpha <= 0){
return m_point1;
}
else if (alpha >= 1){
return m_point2;
}
else{
return GetPositionFromAlpha(alpha);
}
}

Because alpha can be between 0 and 1 as well.

PS: thank you for the great software!
