James R. Barlow 91b42cbfa8 Fix issue in sandwich renderer when skipping OCR on a rotated and deskewed page 
If OCR is skipped due to --tesseract-timeout or similar, and the skip page is rotated with /Rotate, and the skip page was deskewed or had other image processing, then the skip page was created with the wrong dimensions causing the output page to be cropped.

Omitted French because the rare 'oe' and 'ÿ' glyphs are not in Latin-1.
Basically steer people away from HOCR renderer but avoid a potential
disruptive behavior change.

James R. Barlow 2c24f67deb Rename “tess4” renderer to “sandwich” and make it default in Tess 3.05.01 
Tesseract 3.05.01 backported the textonly_pdf=1 which allows the use
of this superior PDF renderer prior to 4.00 alpha. This means that
the tess4 name is no longer accurate, so call it a sandwich because of
its merge-preserve characteristic. Preserve the tess4 name. Fix the
documentation and tests to reflect this.

Make it the default, because it’s better. It does not have the issues
the “tesseract” renderer does prior to Tess 3.05.00 with rendering
PDFs that Ghostscript corrupts, and it produces better output without
re-rastering.

Deprecate some old stuff to avoid the test suite growing obscenely
large.

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