Provide horizontal/vertical flip of graphic

Tom Sawyer draws pretty graphics. the following code:

package ‘ActionSuccession’ {
    item def Scene;
    item def Image;
    item def Picture;
    action def Focus{ in scene : Scene; out image : Image; }
    action def Sh{ in image : Image; out picture : Picture; }    
    action def TakePicture {
        in scene : Scene;
        out picture : Picture;
        bind focus.scene = scene;
        action focus : Focus { in scene; out image; }
        flow focus.image to sh.image;
        first focus then sh;
        action sh : Sh { in image; out picture; }
        bind sh.picture = picture;
    }
}

can be vizualized and after clicking “orthogonal layout” I get this picture:

personally I would prefer to have the in- & outgoing parameters on the left side of the Action “Take Picture”, Therefore: It would be nice to be supported in:

  • selecting some graphical elements

  • activate a “flip horizontally” or “flip vertically” function

    so that I get the “mirrored” graphic.
