matplotlib-2.0.0b1 test errors on Windows #6523
Description
matplotlib-2.0.0b1 on 64-bit Python 3.5 for Windows errors on two tests.
It looks like updating the rcParams at runtime with the full path to ImageMagick's convert tool no longer has any effect during the tests (it still works outside the tests suite).
