Let \(\triangle ABC\) be a scalene triangle. Let \(h_{a}\) be the locus of points \(P\) such that \(|PB - PC| = |AB - AC|\). Let \(h_{b}\) be the locus of points \(P\) such that \(|PC - PA| = |BC - BA|\). Let \(h_{c}\) be the locus of points \(P\) such that \(|PA - PB| = |CA - CB|\). In how many points do all of \(h_{a}, h_{b}\), and \(h_{c}\) concur?
