-Subject: [PATCH] Fix multi.dot Graphviz regression test
-
-Commit d6602ad of 2018-12-01 fixed the regression test broken by commit
-2d55978 of 2016-07-01. This revealed that `test/graphs/multi.dot` was
-failing.
-
-`multi.dot` was introduced in commit 2b3f088 of 2010-11-07 together
-with many of the other tests still here today. It has not been touched
-since. It is a DOT-file containing two digraphs. The regression test
-compares the JPEG images rendered from the DOT-file by pydot with those
-rendered by Graphviz's dot directly.
-
-Commit 66734d2 of 2016-07-01 is the actual cause of the failure. It
-changed one of the render methods of the regression test,
-`_render_with_pydot`, from calculating a single hash for all the JPEG
-images to calculating separate hashes for each JPEG image and then
-concatenating those hashes in one long string. The other render method,
-`_render_with_graphviz`, still calculates a single hash over all data.
-For DOT-files that generate only one image the end result is the same,
-but because `multi.dot` has two graphs, it produces two images and this
-leads to comparing a string of two hashes with one single hash.
-
-I do not think the change in generating the hash was intentional, for
-the following reasons:
-- Commit 66734d2 states that its purpose was to adapt the test to an
-  API change in pydot. It does not mention a deliberate choice to
-  change the testing method.
-- There was no effort to change `_render_with_graphviz` to also produce
-  multiple hashes.
-- Except for easier debugging in case of a failing test with multiple
-  images (AFAICT, only `multi.dot`), I do not see much added benefit in
-  checking a concatenation of the hashes of all images vs. checking one
-  hash of all images together: In both cases the test will fail if one
-  or more images is rendered differently.
-- Given that there were many commits authored that same hour, including
-  commit 2d55978 which broke the regression tests, I suspect the author
-  did not run the tests for each individual commit, but only at the end
-  of that batch, and was therefore also not alerted of this change by
-  the test suite.
-
-Assuming that the change was not intended, this commit will now revert
-`_render_with_pydot` to the old behavior of calculating a single hash
-from all JPEG image data.
-
-Tested with Debian 9.9, Graphviz 2.38.0-17, Python 2.7.13-2 and 3.5.3-1.
