James R. Barlow 4986afca28 hocr: Refactor use of text object 
We don't need to declare the font on each word.

No improvement for removing trailing space or adding \n

James R. Barlow 2b6004a82b hocr: Make words on line use the line height 
Seems to improve the behavior and appearance
of selected text a fair bit.

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 2dff3e07ce Drop libxml2 dependency 
It seems that Python's internal XML parser is good enough to do the job.

James R. Barlow 6b9adef684 Don't create inline images in output PDFs 
...except that Ghostscript will sometimes turn out of line images into
inline images on its own, possibly if file size is small.
