Thanks, but this doesn't seem to be a solution to my problem, because
the figures extend into the right margin always, and I want them to
extend into the outer margin (i. e. left margin on left pages, right
margin on right pages).

I'm now using the following semi-automatic solution, but there is one
problem left:  The alignment is not applied to tikz pictures.  Does
somebody have an idea how to resolve this?

Thank you and kind regards,
Joshua
