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.
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.
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.
