This is an adaptation of the "misc/backgrounds.html" file in the
Serenity image. It tests a lot of background-related properties that we
otherwise have no tests for.
This makes use of the new Gfx::Path::text() to handle SVG text elements,
with this text is just a regular path, and can be manipulated like any
other graphics element.
This removes the SVGTextPaintable and makes both <text> and geometry
elements use a new (shared) SVGPathPaintable. This is identical to the
old SVGGeometryPaintable. This simplifies painting as once something is
resolved to a Gfx::Path, the painting logic is the same.
This removes the awkward hack to recompute the layout transform at paint
time, and makes it possible for path sizes to be computed during layout.
For example, it's possible to use relative units in SVG shapes (e.g.
<rect>), which can be resolved during layout, but would be hard to
resolve again during painting.
This is based on the border-radius.html demo page with text and most
assets removed. This has to be a screenshot based test as there's not
really something else that can be used for comparison.
This also makes the test a little incomplete as things like text
overflow clipping are not tested, but I'd like to avoid this test being
too brittle.
This fixes an issue where the value would be out of sync with reality
in anonymous wrapper block boxes, since we forgot to compute m_visible
after assigning the computed values to them.
Fixes#21106
This adds initial support for `open-quote`, `close-quote`,
`no-open-quote` and `no-close-quote`. We don't yet track the "nesting
level" so we always use the first pair of quotes from the `quotes`
property.
This fixes the sizing of the arrow icons displayed to the left of
parent sections on a table of contents on Wikipedia articles, which
are sized using the equation `calc(max(0.75em, 12px))`. Now, the icon
will not expand past the edges of the box they are within, avoiding
clipping the edges of the arrows.
These apply to any elements that have some kind of open/closed state.
The spec suggests `<details>`, `<dialog>`, and `<select>`, so that's
what I've supported here. Only `<details>` is fleshed out right now,
but once the others are, these pseudo-classes should work
automatically. :^)
Each ref test now links to its reference page with a link tag, in the
same format as WPT:
`<link rel="match" href="reference-page.html" />`
The reference pages have all been moved into a separate `reference/` dir
so that we can just treat every file in `ref/` as a test. There's no
filter to only look at .html files, because we also have a .svg file in
there, and there may be other formats we want to use too. But it's not
too hard to add one if we need it.
