This allows clipping your drawing by any path you like! To do this
all painting has been wrapped around a new draw_clipped() helper
method, which handles the clipping before/after painting.
Note: This clipping is currently missing support for intersecting
clip paths.
This adds CanvasPathClipper and ScopedCanvasPathClip. These allow
clipping the canvas by some arbitrary path.
This initial implementation is fairly naive, with a good few
allocations, though this can probably be improved in future.
Note that the default value of the attribute is true. We were previously
autoplaying videos as soon as they loaded - this will prevent that from
happening until the paused attribute is set to false.
This ports MouseEvent, UIEvent, WheelEvent, and Event to new String.
They all had a dependency to T::create() in
WebDriverConnection::fire_an_event() and therefore had to be ported in
the same commit.
It's not totally clear to me when all of these states are supposed to be
set. For example, nothing in the HTMLMediaElement spec says to "set the
readyState attribute to HAVE_ENOUGH_DATA". However, this will at least
advance the readyState to HAVE_METADATA, which is needed for other
useful attributes for debugging.
The spec for loading a media element is quite huge. This implements just
enough to parse the attribute, fetch the corresponding media object, and
decode the media object (if it is a video). While doing so, this also
implements most network state tracking and firing DOM events that may be
observed via JavaScript.
Some elements, like HTMLMediaElement, must have a unique task sources
for every instance of that element that is created. Support this with a
simple wrapper around IDAllocator.
This is something we're supposed to do according to the HTML spec.
Note that image loading is currently completely ad-hoc, and this just
adds a simple DocumentLoadEventDelayer to the existing implementation.
This will allow us to use images in layout tests, which rely on the
document load event firing at a predictable time.
At the end of HTML::EventLoop::process(), the loop reschedules itself if
there are more runnable tasks available.
However, the condition was flawed: we would reschedule if there were any
microtasks queued, but those tasks will not be processed if we're
currently within the scope of a microtask checkpoint.
To fix this, we now only reschedule the HTML event loop for microtask
processing *if* we're not already in a microtask checkpoint.
This fixes the 100% CPU churn seen when looking at PRs on GitHub. :^)
This solves an awkward dependency cycle, where CalculatedStyleValue
needs the definition of Percentage, but including that would also pull
in PercentageOr, which in turn needs CalculatedStyleValue.
Many places that previously included StyleValue.h no longer need to. :^)
Setting the `data` of a text node already triggers `children changed`
per spec, so there's no need for an explicit call.
This avoids parsing every HTMLStyleElement sheet twice. :^)
We now select between nearest neighbor and bilinear filtering when
scaling images in CRC2D.drawImage().
This patch also adds CRC2D.imageSmoothingQuality but it's ignored for
now as we don't have a bunch of different quality levels to map it to.

When scrolling the page, we may need to flush any pending layout
changes. This is required because otherwise, we don't know if the target
scroll position is valid.
However, we don't need to *force* a layout. If the layout tree is
already up-to-date, we can use it as-is.
Also, if we're scrolling to (0, 0), we don't need to update the layout
at all, since (0, 0) is always a guaranteed valid scroll position.
This fixes a few issues I noticed when playing around with radio
buttons. Previously radio buttons would uncheck checkboxes with
the same "name" attribute, uncheck inputs across different forms,
and treated no name attribute as a group.
This now implements the radio button group check from the HTML spec.
