Finder, Open With, a drop on the Dock icon and `open -a` failed with "VectorCraft cannot open
files in the PDF document format":
- The release Info.plist declared no document types, so Launch Services refused the files before
the app saw them. Info.plist.in now declares every format File › Open reads (the engine's
OPEN_EXTS; a test keeps them in step): VectorCraft owns its own documents and templates and is an
alternate for the others, so it takes over no other app's files. `cargo xtask bundle` now fills
in the same template instead of its own, shorter plist.
- macOS delivers such files as open-document events, not arguments. winit 0.30's application
delegate has no `application:openURLs:`, so AppKit fell back to NSDocumentController, which
refuses every file of a non-NSDocument app (the error in both issues). The new
`open_documents` module adds that method to the delegate's class when the app is about to finish
launching (before AppKit delivers launch files), queues the paths and wakes the UI, which opens
them with `io::open_path` like command-line files; errors go to the status bar too.
New direct macOS dependencies `objc2-foundation` 0.3 and `block2` 0.6 were already in Cargo.lock
(through winit, muda and rfd). The module allows `unsafe_code` for the Objective-C runtime call.
Fixes#354
