[Matplotlib-devel] Manylinux external library test case - matplotlib, tk

What would be better is if we can get rid of the compilation requirement,
but from Michael's comments in the past, it seems that this isn't possible
at the moment. The problem is that the compiled portion provides the image
buffer access, which seems to not be available at the python level. Perhaps
it might make sense to pursue submitting our code to the Tk/Tcl project so
that we might be able to drop this step at some point?
