Add functional "redo OCR" feature
...
Needs argument validation and some other changes. Needs testing
with mixed-content PDFs.
Only really works for pure invisible text at the moment.

Work around loss of Unicode DOCINFO in Ghostscript 9.24+
...
Ghostscript no longer supports UTF-16-BE-hex strings as a way of
supplying Unicode data in pdfmark so we have lost this functionality too:
http://git.ghostscript.com/?p=ghostpdl.git;a=commit;h=e997c6836d243ab37fe3a5f0d57974af95eb5eac
For users this means setting --title, --author, etc. will not work if gs
9.24 is installed, but if the file has existing metadata it might work.
For now we enforce police-state-strict ASCII, until there's time to
implement proper metadata editing. Relevant tests set to xfail.

Draw preview image at full resolution
...
As reported in #281 and confirmed by the test file in #279 , downsampling
the preview adversely affects quality of image rotation especially for
small font sizes and marginal scans.
Full size gets rotation accuracy. This makes rotation a little inefficient
since it rasterizes twice - to be addressed later.
