Excel's draw feature, usually has a bounding box that does not match
the real bounding box.

For example, imagine a "star" object with a shaded tail.  Imagine the
"shade" is very big, like larger than the star and it depends on the
size of the star.

So the bounding box is actually used to control the star, and the
shade changes according to this.

This makes sense.  So we would have an acetate-like canvas item in the
background of the bounding box to keep control of it.  Good idea.
