d32ea8d0dd Remove dead code from qpdf merge + PyPDF2 metadata patching 
I tried "qpdf merge + PyPDF2 metadata patching" first. The problem is
that PyPDF2 produces a 1.3 by default and generally I have less
confidence it.

New approach is to stuff the Document Info metadata in the first page
with PyPdf2, cross fingers and use qpdf to merge. It's not quite as
clean and might harm the first page, but it's better than shipping
files produced by PyPDF2.

5c99acf6d1 Experimental change to use qpdf to merge files (disables Ghostscript) 
All but one tests pass, test_input_file_not_a_pdf

Not sure if PyPDF2 metadata generation will mangle the first page.

ebe68de4ff Functional qpdfmerge with PyPDF2 for DocumentInfo block 
Tests mostly passing. For the moment this is the new default.

Although PyPDF2 produces a PDF-1.3 which will be wrong for some contents
and possible should be repaired with qpdf. Again.

Looks like it could work better to merge PyPDF2 and fix everything
with qpdf.

d257c83520 Most tests were failing at split_pages() 
It seems that ruffus sometimes decides to send a ['inputfile.pdf']
instead of a bare string.

d70e3d3753 ruffus exceptions: for clarity only, don't iterate strings 
It's a good habit to ensure any iterator test is explicit about
allowing or disallowing strings.

Errors seem to be related to either Ghostscript or leptonica? Maybe
-dSAFER?

fef35e4eb2 Fix handling of DPI for rare case of JPEG recompression after deskew/clean 
This test is exercised by page 4 of multipage.pdf. If all images are
JPEGs, and one of deskew/clean removes DPI information, make sure that
we can get the right information back and that the DPI stays square.

b3fcf24a26 Refactor DPI: fix regressions in test suite 
Some called functions are particular about the data format of DPI and
don't like to deal with the Decimal() returned by PyPDF2. Convert to
float and int where needed.

16e4d342d2 Bug fix: --force-ocr should still run on pages with no images 
Useful for people who want to reprocess text.

This also requires --oversample because DPI is undefined. To be fixed
in next commit.

636d1903b3 Ghostscript: do raster output with -dSAFER 
-dSAFER does not work when rendering PDF/A, because that needs to load
the ICC file, and -dSAFER prevents access to external files.

410111d6fb Bug fix: Monochrome images with ICC treated as full color images 
Issue #79.
User submitted PDF with ICC profile attached to the monochrome image
in the input file, which is not common but useful for PDFs that want to
define how light the paper is or how dark the black is. The code was
written to assume unusual images are full color unless it can prove
otherwise. Handle this simple case. Other ICC cases should be tested.

a45505cf1d Fix order of operations in matrix multiplication 
Issue #73. The order of operations happens to not matter for scaling
but does matter for translation. We only need scaling to find the DPI,
so the error was not noticed. Mainly useful to other uses of this
library.
