Shearing process and an example of a bounded support function in $S^0(\mathbb B^2)$

We introduce a process, that we call "shearing", which for any given normal Loewner chain produces a normal Loewner chain made of shears automorphisms. As an application, and in stringent contrast to the one-dimensional case, we prove the existence of a starlike bounded function in the class $S^0$ of the ball $\mathbb B^2$ (in fact the restriction of a shear automorphism of $\mathbb C^2$) which is a support point for a linear continuous functional.
