	    We don't have the code for format-graph-from-root here, so I
    have no idea how it's done... any clues out there?  Thanx!

There's a special kind of stream that buffers multiple pages of graphics.

The simplest way to access it is via dw:do-redisplay, as format-graph-from-root does.

Wrap dw:redisplayer around your code, and call
 (dw:do-redisplay <displayer> <hc-stream> :full-set-cursorpos :graphics :once-only t).
