Patrick Walton 487577a11b Add Metal support. 
This commit substantially reworks the `pathfinder_gpu` API to better support
modern APIs like Metal. It should open the door to `gfx-rs`, `wgpu`, Vulkan,
and D3D12 backends relatively straightforwardly.

A new example, `canvas_metal_minimal`, has been added.

Note that the new Metal shaders require a patched version of `spirv-cross` to
build properly. An upstream patch is forthcoming.

Patrick Walton a1b0df0a42 Rename `Point2DF` to `Vector2F`, `Point3DF` to `Vector4F`, and `LineSegmentF` 
to `LineSegment2F`.

Straw poll on Twitter suggested that these names were preferred.

Patrick Walton 9138e1e0bb Pass in the font context to the canvas rendering context constructor so that it 
can be reused.

Creating a system font source can do I/O on some platforms, so obviously we
don't want to do it every frame.

Patrick Walton e04cc273ee Add enough C bindings to recreate `canvas_minimal` in C. 
Closes #12.
