The UV Edit (Reverse Z) handle is used by the UV Edit SOP to describe
the edit operations requested interactively.

It differs from the UV Edit handle in that the rz parameter is negated
when read from or applied to the operator parameter.

Parameters:

    handle_follow - Whether the handle follows the group.
    handle_p[x,y] - The handle's pivot location.
    handle_rz     - The handle's rotation value in degrees.
    input         - A group field.  The centroid of this group is used
                    as the default origin.
    px, py        - The pivot of the edit operation.
    rz            - The rotation of the edit operation, in degrees.
    sx, sy        - The scale factors of the edit operation.
    trs_order     - The translate/rotate/scale order.
    tx, ty        - The translate amount for the edit operation.
    xyz_order     - The order to apply rz in, thus, irrelevant.
