d3c54fbbde For —rotate-pages, rasterize preview at half DPI instead of 200 DPI 
Ensures that time is not wasted on previews at higher resolution than
the input as was sometimes the case

82cf010333 Error out if trying to produce PDF/A >200” due to Ghostscript limitation 2017-05-25 00:07:29 -07:00

6ff6c8614f —output-type=pdf now outputs /UserUnit PDFs at the correct size 
This currently distorts the output size because Tesseract assumes it
 knows the DPI better than we do.

Does not work for Ghostscript, because it emerges that Ghostscript
honors /UserUnit for rasterizing but not in pdfwrite (resolve/wontfix).

https://bugs.ghostscript.com/show_bug.cgi?id=690781

Ghostscript’s output would need to be patched in a PDF/A safe way for
this to work. Temporary route may be to block Ghostscript if
/UserUnit.

234183ecd2 Fix: Tesseract 3.04 is sensitive to order of configuration commands 
“txt hocr” is not acceptable and does not produce expected output .txt
while “hocr text” works fine, so switch the order everywhere.

Should fix #169

cb06359c0b Turn on Tesseract 4 cache in test suite 
Travis is too slow without it, and perhaps it’s overly paranoid to
never cache Tess4. Maybe nuke the cache occasionally to be safe…

c8a4cbcf17 Fix test suite breakage after sidecar feature added 
Forgot to update tesseract spoofers to account for change in tesseract
parameters.  Also the change to outputting multiple files in the collate
steps affected how ruffus passes information into downstream consumers
of those files.

1e7fbd4202 Fix issues with —pdf-renderer tess4 page skipping 
If tess4 renderer needed to skip OCR on a page it would end up
duplicating the page contents onto the new page, rather than creating
a blank OCR layer and placing it on the output page. This created
duplicated content in output files.

88ef2718f1 Reject high Unicode metadata at command line 
Ghostscript 9.21 does not seem to accept Unicode above U+FFFF. Previous
versions did, but it now exits with a rangecheck error (-15).

Reject on the command line for now. Complete fix would also need to
check input PDF’s metadata.
