I've just updated our GSoC pages with the following.
Port the font-rs rendering engine to FreeType
Raph Levien has developed font-rs[1], an experimental font
renderer written in the Rust programming language. A blogpost
describes some of its features in more detail; of particular
interest is that it is much faster than FreeType's anti-aliasing
rendering module.
The gist of this project would be to port the Rust code to C and
to integrate it into FreeType, providing it as an alternative
rendering engine that eventually might replace the old one. It
would be necessary to investigate how this can be done, and
whether it is feasible at all. In case a port doesn't make sense
(for whatever reasons) it should be investigated whether the ideas
of the code can be used to re-implement the rasterizer in C.
Difficulty: medium (if porting) to high (if reimplementing).
Requirements: Rust, C, Unix build tools. Potential mentors:
Werner Lemberg, Alexei Podtelezhnikov, Toshiya Suzuki (FreeType).
