Comment 14 for bug 481506

Hi,

I am attaching a similar change for the Star shape too.

I am also evaluating if showing the center of rectangles and spirals would make sense too, for consistency.

Finally I'll see if showing the center of the bounding box for any selections (i.e. in src/seltrans.cpp) makes sense, for symmetry with the rotation center.

Any comment is welcome.

Ciao,
