James R. Barlow 8013fd50da 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.

James R. Barlow bb50501369 ghostscript: never use autorotatepages 
It looks like from the gs manual that this parameter is only respected for
vector devices so it never had any effect, but to stay on the safe side,
which it off.

James R. Barlow 1d09061130 Revert previous commit amd reject input images with alpha channel 
Decided on this for simplicity of old release branch.

Modifies baiona.png by stripping
alpha, adds baiona_alpha which
includes the alpha.

James R. Barlow 47885f4230 Remove initial qpdf.repair 
Since pikepdf is doing the work the initial repair takes time and gives
little benefit.

It turns out to not be worthwhile to
save the results of PdfInfo parsing,
since the time to save this seems to exceed the costs of recalculating
it since the "weave" code. At least
for small files.

James R. Barlow 7200623007 Fix installation for Python 3.7 
Need to use private fork of ruffus for Python 3.7. Backward compatible with Python 3.6 for ruffus 2.6.3

Disable locale checking for 3.7 since the various fixes in that release should make it unnecessary.

James R. Barlow 0029cc4fe7 optimize: fix PNGs that were reduced to 1-bit being inverted 
At some point the color gets flipped, we have to flip it again,
for mono.

Incidentally this exposed an unused
optimization. Should change the
first past to scan all images and
record monochrome xrefs, then optimize
JPEG and PNG, possibly adding
mono images to the monochrome
queue. Finally, do JBIG2 optimization.

James R. Barlow 94150f414a Remove qpdf.merge 
We no longer need to merge pages this way. Much of the functionality
was there to implement page splitting without hitting ulimit which
will be fixed in qpdf > 8.0.2. The tests were expensive to run.

Also remove pytest-timeout since it breaks the Linux build.

Since we are no longer splitting pages this is vestigial.
