Object size change?
Now, the transformation panel reflects the size of a shape plus the thickness of the outline if there is one.
For example, a rectangle of 100x100 with an outline (in the middle) of 1 displays a size of 101x101, 102x102 if the outline is external and 100x100 if the outline is internal.
It's a very confusing change! The previous behavior was much more talkative.
I understand that this reflects the actual size, including the outline thickness, but this should be an option. I did not see myself 3 decimal digits when I want a rectangle of 100x100! :)
