This commit moves both the ImageStyleValue and LinearGradientStyleValue
to a common base class of AbstractImageStyleValue. This abstracts
getting the natural_width/height, loading/resolving, and painting
the image.
Now for 'free' you get:
- Linear gradients working with the various background sizing/repeat
properties.
- Linear gradients working as list-markers :^) -- best feature ever!
P.s. This commit is a little large as it's tricky to make this change
incrementally without breaking things.
Previously the clip rect was not relative to the top/left egdes
of the element, which lead to it being positioned incorrectly.
This fixes the clip-rect-auto-004 and clip-rect-auto-005 web
platform tests.
Previously absolutely positioned boxes could only have a % height if
their parent had a absolute height (a height in pixels, em, etc).
This broke some websites/demos such as the "Francine CSS oil painting",
which starts to appear after this commit.

The -webkit version of linear-gradient does not include the `to`
before a <side or corner>. The angles of the <side or corner>
for the webkit version are also opposite that of the standard one.
So for the standard: linear-gradient(to left, red, blue)
The webkit version is: -webkit-linear-gradient(right, red, blue)
Adding the `to` in the -webkit version is invalid, omitting it in
the standard one is also invalid.
Defer serialization of the concatenated strings until later. This is
used heavily in SunSpider's string-validate-input subtest, which
sees a small progression.
Instead of concatenating string data every time you add two strings
together in JavaScript, we now create a new PrimitiveString that points
to the two concatenated strings instead.
This turns concatenated strings into a tree structure that doesn't have
to be serialized until someone wants the characters in the string.
This *dramatically* reduces the peak memory footprint when running
the SunSpider benchmark (from ~6G to ~1G on my machine). It's also
significantly faster (1.39x) :^)
Converts Minesweeper's main widget to GML, polishes the custom
game window, formats the clock as human readable digital time, and
defers invoking Field's callback until the main widget has finished
relayout. Fixes inability to downsize the main window when shrinking
field size.
This patch replaces the concept of fixed resizees with opportunistic
ones which use the new SpecialDimension::OpportunisticGrow UISize.
This lets us simplify splitter resize code and take advantage of
the layout system's automatic calculations for minimum size and
expansion. Functionally the same as before, but fixes Splitter's
unintended ability to grow window size.
Assignments actually forward to window.location.href, as the spec
requires. Since the window object is implemented by hand, this looks a
little janky. Eventually we should move all this stuff to IDL.
This patch implements the "create a new browsing context" function from
the HTML spec and replaces our existing logic with it.
The big difference is that browsing contexts now initially navigate to
"about:blank" instead of starting out in a strange "empty" state.
This makes it possible for websites to create a new iframe and start
scripting inside it right away, without having to load an URL into it.
We can't rely on the caller to keep the code points alive, and this
was sometimes causing incorrect cache hits, leading to the wrong
emoji being displayed.
Fixes#14693
The way we've been creating DOM::Document has been pretty far from what
the spec tells us to do, and this is a first big step towards getting us
closer to spec.
The new Document::create_and_initialize() is called by FrameLoader after
loading a "text/html" resource.
We create the JS Realm and the Window object when creating the Document
(previously, we'd do it on first access to Document::interpreter().)
The realm execution context is owned by the Environment Settings Object.
The existing implementation of this AO lives in Interpreter::create(),
which makes it impossible to use without also constructing an
Interpreter.
This patch adds a new Realm::initialize_host_defined_realm() and takes
the global object and global this customization steps as Function
callback objects. This will be used by LibWeb to create realms during
Document construction.
A lot of code assumes that there's a current execution context. By
setting up a dummy context right after creating the main thread VM,
we ensure that such code can always run.
