    ...On page 7B-274, the macros "dw:with-output-recording-disabled" and
    "dw:with-output-recording-enabled" are mentioned, and could be promising.
    However, I was unable to find them in the documentation.  This appears to
    be a bug.

They are documented (very briefly) on page 7A-90.  However, remember
that output produced while in WITH-OUTPUT-RECORDING-DISABLED can't be
clicked on, so there's not much point to making it be a presentation.
The output recording disable facility is often used when you don't have
as much control over whether the output is done using presentations; for
instance, if you use FORMAT to display some non-recorded output.
Another use is when a presentation wants to be temporarily non-recorded;
for instance, if you drag a presentation with the mouse, you only want
the final location to be recorded, so you would disable recording while
dragging it, but re-enable when it is placed in its final position.  If
your sprite is continuously moving (that's my understanding of what
sprites do), then this might not be right for you.
