As y'all may have seen, I've been working on building manylinux wheels for matplotlib

I have an automated build script for matplotlib 1.5.1, that adds a version of PR #6442 to enable tkagg.

Thanks to Thomas' help over at #6469, these wheels are passing all tests on a fresh install into travis-ci containers.

Olivier Grisel has installed and tested on his Ubuntu 14.04 machine. I have also installed and tested on a Debian Jessie VM.

I think these wheels are now ready to deploy on pypi. Do y'all agree? Is there anything else I should build into these wheels (see the build script link above)? Are there any other tests I / we can do?
