(display-size) gives you the display-size of the value FO, but the
display-size of a displayed flow object is the width of the container it is
filling.  For example, if you have a displayed external-graphic inside a
simple-page-sequence, the display-size for the graphic will be the width of
the page less the sum of the left and right margins.

Anywhere you can use a length-spec, you can use a length. You don't need
(make-length-spec 500pt); just use 500pt.
