Found it; screenshot attached. And now I remember where I saw the
hollow rectangles --- it wasn't in a document, but on the GUST
website.

@John: we have now found

* \fakewords: uniform black slabs with a thin line underneath to
suggest descenders
* Code to convert letters to filled rectangles
* An example of letters-to-outlined-rectangles in the TeXbook
* Outlined rectangles on the GUST homepage.

Was any of these the fake text you were remembering, or do you think
there is still something else? This seems a nice occasion to complete
the wiki's [[Dummy text]] article. (Which also mentions the ipsum
module for lorem ipsum text, by the way.)
