As english isn't my native language I'm not sure to find the right words.
Manual says it "computes the width of an object" (see:
http://lilypond.org/doc/v2.19/Documentation/extending/callback-functions.html
).
With "my" words I'd say that it'll help you to add or reduce the space
before and/or after a grob.
Cheers,
Pierre
