I'm getting one test failure on v1.1.x (clean font cache, clean build):

FAIL: matplotlib.tests.test_mathtext.mathfont_stix_14_test.test

I thought maybe the recent ttconv commit could be playing a role here so i tested on f929f74 and still see it, so 70e9c33 does not appear to be implicated. It looks like a small pixel shift in some of the characters. Anyone else seeing this?

Also, I was trying to run the single test semantics on this, and tried a few variants of:

msierig@pinchiepie:matplotlib.matplotlib> python tests.py  matplotlib.tests.test_mathtext:mathfont_stix_14_test.test
E
======================================================================
ERROR: Failure: ValueError (No such test mathfont_stix_14_test.test)

    raise self.exc_class(self.exc_val)
ValueError: No such test mathfont_stix_14_test.test

Ran 1 test in 0.002s

What is the magic incantation for running this as a single test?
