This lets the user zoom in and out on a web page using the View menu or
keyboard shortcuts. This does not implement zooming with ctrl+scroll.
In the future, it'd be nice to embed the zoom level display inside the
location toolbar. But to do that, we will need to invent our own custom
search field and all of the UI classes (controller, cell, etc.) to draw
the field. So for now, this places the zoom level display to the right
of the location toolbar.
This lets the user choose a color scheme which differs from the active
system theme. Upon changing the color scheme, the scheme is broadcast to
all active tabs, and will be used in new tabs.
We can easily add hooks to notify the browsers of these events if any
implementation-specific handling is needed in the future, but for now,
these only repaint the client, which we can do in ViewImplementation.
Storing the backup bitmap is the same across Browser and Ladybird. Just
peform that work in LibWebView, and handle only the implementation-
specific nuances within the browsers.
This also sets the default callback to do what every non-Serenity
browser is doing, rather than copy-pasting this callback into every
implementation. The callback is still available for any platform which
might want to override the default behavior. For example, OOPWV now
overrides this callback to use FileSystemAccessClient.
This adds an alternative Ladybird chrome for macOS using the AppKit
framework. Just about everything needed for normal web browsing has
been implemented. This includes:
* Tabbed, scrollable navigation
* History navigation (back, forward, reload)
* Keyboard / mouse events
* Favicons
* Context menus
* Cookies
* Dialogs (alert, confirm, prompt)
* WebDriver support
This does not include debugging tools like the JavaScript console and
inspector, nor theme support.
The Qt chrome is still used by default. To use the AppKit chrome, set
the ENABLE_QT CMake option to OFF.
