Stop copying images every frame on CPU.
...
We can avoid reuploading them to the GPU every frame as well, but this is a
bigger, and easier, win for now.

Composite render targets using tiles, taking the Z-buffer into account.
...
We can do more tile-based optimization, but this should be enough to ensure a
correct rendering.
This temporarily breaks subpixel AA, but it should be fixable by modifying
`blur.fs.glsl`.
Closes #271 .

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.

Replace layers with render targets, which can be used as patterns.
...
This allows us to efficiently handle a lot of workloads that require multiple
HTML canvases, without CPU readback. For example, you can render paths to a
render target, then turn that render target into a repeating pattern that you
fill other paths with. Or you can render paths to a render target and then
composite that render target as a whole with a blend mode.
This introduces a new `DrawRenderTarget` render command that blits a render
target without any paths involved. This is basically just a hack that works
around the fact that our tiled renderer doesn't yet support effects that widen
the ink region (i.e. blurs). It can be removed once we have that support.

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.
