I think you can use the Scheme function chain-assoc-get to get the value
of any property.  In fret-diagrams.scm I used the function to get the
value of 'top-fret-thickness.

(chain-assoc-get 'top-fret-thickness props 3.0)

This code returnd the value of 'top-fret-thickness if it is defined in
the alist-chain props.  If 'top-fret-thickness is not defined, it
returns the value of 3.0.
