Nico Weber ec739460e0 LibPDF: Add test for SampledFunction and fix bugs found by it ...

* SampledFunction now keeps the StreamObject it gets data from alive
  (doesn't matter too much in practice, but does matter in the test,
  where nothing else keeps the stream alive).

* If a sample is an integer, we would previously sample that value
  twice and then divide by zero when interpolating. Make sure to
  sample 1 unit apart.
