getRow method
Gets the row of the matrix
Implementation
Vector4 getRow(int row) {
final Vector4 r = new Vector4.zero();
final Float32List rStorage = r._v4storage;
rStorage[0] = _m4storage[index(row, 0)];
rStorage[1] = _m4storage[index(row, 1)];
rStorage[2] = _m4storage[index(row, 2)];
rStorage[3] = _m4storage[index(row, 3)];
return r;
