- Integrate pdf-tools.cc with the rest of the code
-- What if an input page specifies /Rotate?

- What should do modulo(half) with an odd number of tuples? Improve, or at least document.
+- Modulo with last tuple incomplete: sometimes, not padding the last tuple can be useful

+- Better range syntax for "from N to end" or "the whole document"
+- nup: allow stacking ("1 3 5 7" "2 4 6 8")
