Patrick Walton 42289eec6e Fix Metal memory management and the `canvas_metal_minimal`, `canvas_nanovg`, 
and `macos_app` examples.

`winit` does not create an autorelease pool, so the Metal backend had not taken
the presence of one into account. Now the Metal backend creates and flushes
autorelease pools as necessary.

Closes #334.
Closes #376.

Patrick Walton f607b607b0 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.

Patrick Walton 0f35d9c817 Add an embedded resource loader that places resources directly in the binary. 
This is useful for WebGL and for downstream crates.io use.

Emmanuel Gil Peyrot 6ce416e77c Bump all outdated dependencies 
I’m pleasantly surprised that none of these required any (visible) code
change, but tests pass so let’s go with that. :)

Patrick Walton 2db43797c3 Split colors out into their own crate. 
A lot of downstream consumers of `pathfinder_gpu` want to use colors without
the path stuff.

Patrick Walton 431dcf3d2e Rename `pathfinder_geometry::basic` to simply `pathfinder_geometry`, and move 
the remaining code in that crate to a new crate, `pathfinder_content`

The old hierarchy was confusing.

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.
