Summary0009544: Vector projection function
DescriptionI didn't see anything like this in vtkMath, does it exist somewhere else? Or can this be added somewhere?

void Project(const double* A, const double* B, double* Projection)
{
    //find the projection of A on B
    double scale = vtkMath::Dot(A,B)/pow(vtkMath::Norm(B), 2);
    for(unsigned int i = 0; i < 3; i++)
        Projection[i] = scale * B[i];
}

A "ProjectVectorOnPlane" function would probably also be useful.
