By combining --linearize with --compress-streams=n, we ensure that no
new compressed data will appear in linearized output, which makes the
output independent of zlib's output. There are other tests to ensure
that linearization works correctly with compression. This commit
involves changing some test outputs and test code as well just
updating test suites.
This comment expands all tabs using an 8-character tab-width. You
should ignore this commit when using git blame or use git blame -w.
In the early days, I used to use tabs where possible for indentation,
since emacs did this automatically. In recent years, I have switched
to only using spaces, which means qpdf source code has been a mixture
of spaces and tabs. I have avoided cleaning this up because of not
wanting gratuitous whitespaces change to cloud the output of git
blame, but I changed my mind after discussing with users who view qpdf
source code in editors/IDEs that have other tab widths by default and
in light of the fact that I am planning to start applying automatic
code formatting soon.
