 The affine co-ordinates for a point describe a point in terms of its x and y
 position. The functions EC_POINT_set_affine_coordinates_GFp() and
 EC_POINT_set_affine_coordinates_GF2m() set the B<x> and B<y> co-ordinates for

 As well as the affine co-ordinates, a point can alternatively be described in
 terms of its Jacobian projective co-ordinates (for Fp curves only). Jacobian
