How do I automatically fit objects to the size of a drawn canvas?

In previous versions of Word it was very easy to make the canvas fit exactly
the objects drawn on the canvas. I just clicked on a "rectangle" in the upper
left corner, just above the canvas and the canvas adjusted to fit the drawn
objects exactly. No extra white spaces around them and/or the canvas grew to
fit all objects.

In the new Microsoft Word 2007 I can't find the "rectangle" or any other way
of adjusting the canvas size in this way to precisely fit the drawn objects.

If I try to change the size of the drawing in word the size of the whole
drawing changes including for example unecessary space to the right and that
is not what I want.
Anyone know how to fit the canvas to the objects?
