[Matplotlib-devel] image tests fail locally on my OSX system

[Eric Firing]

On my normal environment, OSX 10.12.6 on a Macbook Pro Retina, I am 
getting multiple image test failures that are *not* just the usual 
freetype problems.  (I am using 'export MPLLOCALFREETYPE=1' in my 
.bashrc.)  The failures are most visible in the diffs of the spectrum plots.

Is anyone else seeing this, or are others on OSX able to get all of the 
tests to pass?
