Glyphy, a text renderer implemented using OpenGL ES2 shaders:

Glyphy uploads typeface vectors to the GPU and renders text in real time, performing perspective correct antialiasing.

 

Maybe this could be useful for the Engine Josh.

Ok this is pretty cool. I sugested that Limit Theory (a awesomely looking and upcoming space game) to implement SDF:

After a couple of months he did it! With better font render quality and performance than the old solution (through SFML):

Here is the result (30:01 in to the dev video ... the link point to that part of the video ):

 

I think you should do what he did. Implement SDF your self and do not use third party stuff.
