Thanks Sven, I've found it here:

http://www.directfb.org/index.php/viewcvs.cgi/DFBSee/src/rotate.c?rev=1.6&content-type=text/vnd.viewcvs-markup

This provides a rotate_blit function:

void
rotate_blit (IDirectFBSurface *destination,
              IDirectFBSurface *source,
              RotationType      rot,
              int               x,
              int               y)

It's a software copy; there's no hardware blitting going on.  Perhaps 
this would be something useful to add to directfb itself?

I'm continuing to look at whether this can more efficiently be done 
during JPEG decoding.

Cheers,

Phil.
