A question from the client:

Freetype - why did you need to modify the externals at all, specifically freetype?

Let's make sure to document what changes are needed to Freetype, and ideally we should be able to use the unmodified externals version.

We would like this fixed before we merge the pull request to johnrobinsn/pxCore.
