Rasterific is a Haskell rasterization engine (a vectorial renderer) implemented on top of JuicyPixels. Rasterific bases its text rendering on FontyFruity.
The renderer design is based on the Nile / Gezira renderer from the STEP project from the VPRI institute. The interesting thing about this renderer is the conciseness of it's implementation, providing antialiased rendering in the way.
