James R. Barlow 36a53a7b37 Weave: Unconditionally rotate and scale the text layerThis solves two issues. First, the text layer can end up being adifferent size, probably if the DPI is not an integer; scaling helps itfit slightly better. Second, other printable text on the page can end uphorizontally scaled or misaligned if we don't all of our drawing in aq/Q pair. 2018-05-10 19:03:31 -07:00
James R. Barlow 0a5982a902 PyMuPDF tweaks: don't clean 
In MuPDF 1.13 clean might be unreliable, so explicitly don't do it,
even though it doesn't cause trouble in 1.12.

James R. Barlow b8f3ead541 Remove tesseract renderer entirely 
Grafting lets us work with older Tesseract versions as if they could use
sandwich, so there is no point in keeping it. It's been deprecated for a
long time now anyway.

James R. Barlow e0bb898f29 Remove hocr debug renderer (-g) 
The fact that this produces additional pages makes it a maintenance
burden. hocr can be debugged using hocrtransform.

James R. Barlow 8a9f174f63 Fix XMP validation issue with /CreationDate 
Related to previous validation issue. If the /CreationDate had no
timezone, Ghostscript also creates invalid metadata. Work around this.
Also fix up PDF date decoding, and transcode dates to standardize them.

Passing is invariant with this change.
