Oh, I see. I'm sorry I don't know what is going wrong. Different
versions of cairo/pango could be relevant, possibly.
I doubt it is going to matter, but if you change the expression on
line 932 in collects/mrlib/image-core.rkt:
(send dc draw-text (text-string np-atomic-shape)
(real-part p)
(imag-part p)
#f 0 θ)
by turning the #f into a #t, does that change anything?
