Some content cause a lot of paint invalidations (e.g someone drawing to
a <canvas> repeatedly) and we don't need to spam the client about this.
Instead, accumulate a dirty rect, and send it once per event loop step.
This is in preparation for implementing JS scrolling functions, which
specify both x and y scrolling deltas. The visible behavior has not
changed.
Also, moved the "mouse wheel delta * 20" calculation to the
`EventHandler` since the JS calls will want to work directly in pixels.
This allows WindowServer to use multiple framebuffer devices and
compose the desktop with any arbitrary layout. Currently, it is assumed
that it is configured contiguous and non-overlapping, but this should
eventually be enforced.
To make rendering efficient, each window now also tracks on which
screens it needs to be rendered. This way we don't have to iterate all
the windows for each screen but instead use the same rendering loop and
then only render to the screen (or screens) that the window actually
uses.

To protect the main Browser process against nefarious cookies, parse the
cookies out-of-process and then send the parsed result over IPC to the
main process. This way, if the cookie parser blows up, only that tab
will be affected.
To implement the HttpOnly attribute, the CookieJar needs to know where a
request originated from. Namely, it needs to distinguish between HTTP /
non-HTTP (i.e. JavaScript) requests. When the HttpOnly attribute is set,
requests from JavaScript are to be blocked.
In single process mode, the browser will display a page's favicon in
both the location bar and tab. This adds the same support for multi-
process mode.
When a mousewheel scroll event isn't handled by the web content
itself (e.g. an overflowed box or similar), the event needs to get
passed back up to the OutOfProcessWebView.
This patch adds an IPC call for debugging requests. It's stringly typed
and very simple, and allows us to easily implement all the features in
the Browser's Debug menu.
This is a workaround until we can implement a proper <input type=text>
in terms of LibWeb primitives.
This makes google.com not crash in multi-process mode (but there is no
search box.)
