commit 13ef1642
Author: Armin Le Grand <alg@apache.org>
Date:   Wed Nov 21 13:23:01 2012 +0000

    For backward compatibility take mirrorings in setTransformation into account

    Also found an error in SdrObjCustomShape::TRGetBaseGeometry when MirrorY was used

    (cherry picked from commit 4116c33b)
