Implement the HSL filters (called "non-separable blend modes" in the spec).
...
These cannot be implemented with the standard OpenGL blending functions, so we
have to do them manually in a shader, which requires a good deal of machinery
to create intermediate framebuffers and so forth.

Add support for multiple paint texture pages.

This avoids arbitrary limits on the number of images, gradients, etc. you can
have.

A lot of downstream consumers of `pathfinder_gpu` want to use colors without
the path stuff.

Use 2-lane instead of 4-lane SIMD types for 2D vectors.
...
Also, this commit rewrites the `add_fill()` method to stop using shuffle
instructions, which can be slow and make the code overly complicated. The
shuffle instructions have been removed from the various SIMD backends.

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.

Add Metal shaders, cross-compiled from the GLSL via SPIR-V.

The Metal shaders are checked into the repository for convenience, but they
should not be directly edited. Instead, edit the corresponding GLSL shader in
the top-level `shaders/` directory, and rerun `make` in there.
