Patrick Walton 6a7c013e61 Make the hints a uniform instead of a buffer texture.
Saves a good bit of memory traffic during vertex shading.

Patrick Walton 157292175b Use instanced rendering in the 3D demo.
This massively decreases the load time and memory usage in exchange for more draw calls.

Patrick Walton 70ab2d55f3 Don't count resolution time in the benchmark.
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.

Manish Goregaokar 9a0fa96d4f
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.

Patrick Walton c36896e337 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.)
