Transform shear (real xy, [real xz = 0, [real yx = 0, [real yz = 0,
[Function]
[real zx = 0, [real zy = 0]]]]])
Creates a Transform t locally and calls t.shear(xy, xz, yx, yz, zx, zy ). t is then
applied to all of the Points on points. The return value is t.
Point p0;
Point p1(1);
Point p2(1, 1);
Point p3(0, 1);
Path q("--", true, &p0, &p1, &p2, &p3, 0);

q.shift(1);

q.shear(1.5, 2, 2.5, 3, 3.5, 5);
