Screenshots for tests are taken in headless mode now, in which case the
window does not show up Dock.app. In addition, servoshell now supports
taking a screenshot in headed mode, in which case one can keep using the
browser after the screenshot happens. Hiding the window makes this
impossible. Given these two things, it seems that this functionality
isn't necessary any longer.
Testing: It's difficult to test this kind of system integration with
servoshell.

Mouse button events are sent in CSSPixel coordinates, but these need to
so they need to converted into device coordinates when creating an input
event for them. This isn't an issue for automated test because they
always use a scale factor of 1. This is a problem when running
interactively and not in headless mode.
Testing: This isn't really testable in an automated way, but is very
obviously
causes tests to pass when run with WebDriver and without headless mode.
Fixes: Part of #38087.

Instead of having every single embedder implement keyboard scrolling,
handle it in script in the default key event handler. This allows
properly targeting the scroll events to their scroll containers as well
as appropriately sizing "page up" and "page down" scroll deltas.
This change means that when you use the keyboard to scroll, the focused
or most recently clicked `<iframe>` or overflow scroll container is
scrolled, rather than the main frame.
In addition, when a particular scroll frame is larger than its content
in the axis of the scroll, the scrolling operation is chained to
the parent (as in other browsers). One exception is for `<iframe>`s,
which will be implemented in a followup change.
Testing: automated tests runnable locally with `mach test-wpt --product

This change removes the `DebugOption` (`-Z`) for touch event simulation
and moves the implementation of the feature to servoshell. The resaoning
for this is:
- This is really a servoshell feature and can be implemented on top of
the API. This moves more code out of the already too-complicated
renderer.
- I would like to consolidate `DebugOptions` into a `ServoLogOptions`
to collect all options for configuring Servo logging. This requires
moving away all of the non-logging options.
- Eventually touch event simulation will be able to reuse the fling
implementation from servoshell as we are actually simulating touch
events sent to the `WebView`.
Testing: This changes a conditional feature that's used for manual
debugging.
It is difficult to write tests for this as there are no servoshell tests
that
verify input handling.

Make several changes which should address panics and inconsistent
behavior around attempts to set extreme sizes:
1. Limit the minimum size of the `RenderingContext` to 1 pixel by 1
pixel. This should address problems where users of the API try to
directly set the size to a zero or negative dimension. In addition,
improve the documentation around `WebView::resize` to mention this.
2. Clamp values sent in the `WebViewDelegate::request_resize_to` method
to be at least 1x1. This prevents Servo from sending nonsense values
to embedders. Improve documentation in this method.
3. In servoshell:
- More consistently clamp inner and outer window size values.
- Clamp all resize values to the available screen size, so that
large screen sizes aren't processed directly.
Testing: This change fixes an existing WPT and adds two new API tests.

This includes some small refactoring and some small breaking changes as
listed below. Other than these I tried to keep the functionality exactly
the same but because in the old code the parsing and settings of
preferences was intermingled it was difficult to figure out.
Small Breaking:
- Size and resources-path were unused but appeared in the help.
- soft-fail and hard-fail: Soft-fail flag got removed because it is too
difficult to keep both. The default is now soft-fail and hard-fail can
be enabled.
- The help strings are obviously formatted differently now.
- -V does not work anymore but -v and --version.
Ideally, we want to have the ServoShellPreferences and Preferences be
directly the Argument structure but that needs a bit more discussion
because it would break backwards compatibility with the commandline.
This increases the binary size by ~280kb.
Testing: The testcases are still working but they do not cover much.
I added a unit test for the -p flag because it is the most difficult to
parse in general.
Fixes: This will fix a small number of various parsing misshaps. It will
also show if we are removing an option via unused lint.

Building on the preference observer work from #38649, we now
automatically install an observer when multiprocess mode is enabled.
This observer notifies the constellation of updated preferences, which
in turn notifies each content process so the changes will be reflected

Implment get window handles according to
[spec](https://w3c.github.io/webdriver/#dfn-window-handles).
- Window handles are supposed to identify `browsing context`. However,
based on `get window handle command` and `get window handles command`,
we only need to care about top level browsing context.
- Back then, we use a random generated uuid for eacch webview id, it is
not correct but still work because all commands depend on `webview id`
and `browsing context id`. The only case we need window handle is is
when webdriver gets window object with js script. Since the object is
converted to the id of window's document node, `get window handle`
should return the same thing.
Action run (with updated expectation):

Properly send `mouseleave` events when the cursor moves between
`<iframe>`s. This allows a better handling of cursor changes and status
text updates. Specifically, we do not need to continuously update the
cursor and the value can be cached in the `Document`. In addition,
status updates can now be sent properly when moving focus between
`<iframe>`s.
Note that style updates for `:hover` values are still broken, but less
so than before. Now the hover state on the `Node` is updated, but for
some
reason the restyle isn't taking place properly. This maintains the
status quo as far as behavior goes when hover moves between `<iframe>`s.
This change also adds a helper data structure to `Document` which will
eventually be responsible for event handling.
Testing: Cursor and status change are currently very hard to test as
the API test harness makes this difficult at the moment.

For current implementation, when a command may trigger a navigation,
webdriver only waits for document readiness state.
However, not all navigations make change in document.
This PR handles more cases for waiting for a navigation, and apply to
`element_click`.
- Before sending a command which may trigger a navigation, `webdriver`
sets `load status send` to `embedder`, `constelltation` and `script
thread` to listen to `navigation events`.
- Webdriver check if there is a navigation with `script thread`.
- If the navigation is loading a new url, webdriver checks if the
request is approved with `constellation`, then waits for document
readiness state.
- If the navigation is a hashchange, webdriver waits untill all new
generated dom events have been processed.
