Fix “deskew-rotate” bug.
...
Turns out this occurred in any case where pdf-renderer hocr was used
and a tesseract timeout or error occurred. We created a replacement
page based on the unrotated page dimensions instead of the input image’s
dimensions.

Refactor exit codes; test for missing tessdata
...
Some versions of tesseract installed by homebrew end up without a
functional tessdata folder, and tesseract is not helpful in this
situation, so add a new test to make sure our output is at least
indicative of the problem.
In the process of properly handling return codes I discovered
test_override_metadata triggers a NPE inside JHOVE probably due to the
Unicode character checking. This could be specific to my JRE (1.6.0_65,
Oracle) but it's probably JHOVE's fault. A valid PDF/A (per Acrobat)
is still generated.
