* Create common web view registry and unify title setting
* Consistently use space-separated naming for webview titles
None of the modified titles seem to be in use by add-ons, so we are not bound to the current naming.
The old naming was likely following camelCase as the name was also acting as a key for saveGeom, which is no longer the case.
* Update webview_did_inject_style_into_page example
* Add docstring to addon-targeted method
* Change AnkiWebView.origin to property
* Fix dupe enum value
* Tweak method name
* Add semicolon
* Rename `AnkiWebViewOrigin` to `AnkiWebViewKind`
* Use submodule imports in aqt
* Use submodule imports in pylib
* More submodule imports in pylib
These required removing some direct imports to get rid of import cycles.
The enum changes should work on PyQt 5.x, and are required in PyQt 6.x.
They are not supported by the PyQt5 typings however, so we need to run
our tests with PyQt6.
This adds Python 3.9 and 3.10 typing syntax to files that import
attributions from __future___. Python 3.9 should be able to cope with
the 3.10 syntax, but Python 3.8 will no longer work.
On Windows/Mac, install the latest Python 3.9 version from python.org.
There are currently no orjson wheels for Python 3.10 on Windows/Mac,
which will break the build unless you have Rust installed separately.
On Linux, modern distros should have Python 3.9 available already. If
you're on an older distro, you'll need to build Python from source first.
