Cannot merge in this shape, and the failure is not what it looks like.

The macOS build loses every RenderContext method on CoreGraphicsContext at once. That is not an API change in piet 0.8: piet-coregraphics stayed on 0.6.2 and pins an exact piet, so the graph carries piet 0.6.2 and 0.8.0 together and CoreGraphicsContext implements the trait from the copy nothing else uses.

Taking both is a larger change than a bump. piet-coregraphics 0.8.0 requires core-graphics ^0.24; this tree pins core-graphics = "0.22" under cocoa = "0.24", so the pair needs a coordinated macOS stack upgrade with a real macOS build behind it.

#41 adds a Dependabot group so the pair arrives in one pull request instead of as a half that can never compile, and corrects the Cargo.toml note that said this cost applied only from piet 0.7.

OK, I won't notify you again about this release, but will get in touch when a new version is available. If you'd rather skip all updates until the next major or minor version, let me know by commenting @dependabot ignore this major version or @dependabot ignore this minor version. You can also ignore all major, minor, or patch releases for a dependency by adding an ignore condition with the desired update_types to your config file.

If you change your mind, just re-open this PR and I'll resolve any conflicts on it.
