This means that users of Pathfinder will have to accept floating point
textures in order to get the advertised performance, but as they're well
supported on all modern GPUs I don't consider that much of a problem.

demo/client: Make WASD composable
...
Currently movement works in the direction of the latest key pressed.
Moving diagonally is not possible, and if you are pressing two keys
and release one, movement stops instead of switching over.
This keeps track of the key press state and updates the movement delta
accordingly, leading to much more natural/pleasant WASD navigation.
Note than onKeyDown is called multiple times when you press and hold,
so we must keep track of this state ourselves.

Implement path stroking using the FreeType stroker.
...
I'm not too happy with this, as I discovered a segfault in FreeType that doesn't give me confidence
in this as a solution for the long term. Additionally, this exposes the problems in the partitioner
with lack of winding fill rule, proper handling of self-intersections, and splitting of paths at
their extrema. (I believe these problems should be fairly straightforward to handle, but we just
don't handle them yet.)
