Tucker Barbour 9fd9c7a51f Scale BoundingBox and Text elements to account for additional space. 
Here we are manually scaling the pt width used for the BoundingBox and
the Text element when manually adding whitespace to account for
limitations of the PDF.js viewer. This fixes an initial regression
noticed when selecting text elements in Chrome and PDFium. The width
of the Text element and BoundBox had not been adjusted for the
additional whitespace so the highlighting was offset slightly.

Tucker BarbourandCharles Forcey e6e34251c6 Add option to explicitly add interword spaces to HOCR pdf-renderer 
This commit includes an optional work around for limitations of the
PDF.js viewer described in
https://github.com/jbarlow83/OCRmyPDF/issues/133. Here is explicitly
add an addition space to text elements before drawing them on the PDF
canvas when using the HOCR renderer. This option does not apply to
other pdf renderers in OCRmyPDF and is turned off by default.

James R. Barlow 3de83627a9 Handle output to /dev/null or directory (#219) 
Previously we threw an exception if the output name was a directory (only after doing OCR) and would trigger a PermissionError on trying to flip permission bits of /dev/null due to shutil.copyfile implementation. Instead of copying file use shutil.copyfileobj which should also respect umask etc.

James R. Barlow 1dfc32d7e6 Preserve "text as curves" vector content 
Never updated the checking logic to deal with a pure vector file with no text that needs an OCR layer. This is doable, so allow it.

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.
