BUG: Old texlive-full debian package causing cropping issues with jpg files
Crops / processes jpg images incorrectly sometimes. When the file is png it isn't occuring.
This is XeTeX, Version 3.14159265-2.6-0.99992 (TeX Live 2015/dev/Debian) (preloaded format=xelatex)
loads LaTeX2e <2014/05/01>
while on my mac its at LaTeX2e <2015/01/01>
So I think the stable debian package used in the current docker image is still on the stable https://packages.debian.org/jessie/texlive-full and should have the contents of https://packages.debian.org/stretch/texlive-full for this to be over.
