James R. Barlow fe14cb57c0 Fix ruffus exception output 
I found this issue in ruffus 2.6.3
https://github.com/bunbun/ruffus/issues/65
also discussed here
https://github.com/bunbun/ruffus/pull/67

ruffus 2.6.3 RethrownJobError don't follow the normal conventions and
so its exception causes problems when they cross process boundaries.
This change carefully examines the various forms of ruffus exception
objects that can appear in 2.6.3 and parses them more carefully. It
also removes any direct posting of the exception to the logger because
this triggers another serializing of the exception object, mutating it
further.

James R. Barlow 5b7c8cf5d3 Remove check for /ImageMask 
/ImageMask means the the image is a stencil mask for a grayscale or
color image. From issue #63 a user has a PDF apparently with only a
stencil mask and no other images. According to PDF spec you're supposed
to use masks to help draw other images rather than draw masks
explicitly, although drawing masks is not forbidden.

In the event that the image mask is higher resolution than the input
 image, the composite image should be drawn at the highest DPI to a
ccurately capture the effect of the mask. It looks like the right to
 do is take masks into account rather than ignore them (a holdover
from earlier, less robust versions), or don't treat it different.
