Calculate a "preferred aspect ratio" based on the value of
`aspect-ratio` and the presence of a natural aspect ratio, and use that
in layout.
This is by no means complete or perfect, but we do now apply the given
aspect-ratio to things.
The spec is a bit vague, just saying to calculate sizes for
aspect-ratio'ed boxes the same as you would for replaced elements. My
naive solution here is to find everywhere we were checking for a
ReplacedBox, and then also accept a regular Box with a preferred aspect
ratio. This gets us pretty far. :^)
https://www.w3.org/TR/css-sizing-4/#aspect-ratio-minimum is not at all
implemented.
Having this here instead of in ReplacedBox means we can access it when
figuring out what the "preferred aspect ratio" is.
There's some inconsistency between specs about what this is called, but
they're moving towards referring to this as "natural width/height/
aspect-ratio", so let's copy that terminology.
Anywhere that `<number>` appears in the grammar, `calc()` that resolves
to a number is valid, including inside the `<ratio>` grammar.
Thankfully, a calculation that produces a number cannot rely on any
context information for the calculation, so we can resolve them
straight away and just pretend they were a `<number>` the whole
time. :^)
`foo.is(Token::Type::Delim) && foo.token().delim() == '!'` becomes
`foo.is_delim('!')`, which is a lot less verbose. I really should have
done this ages ago.
These are superseded by headless-browser running these tests in a single
process, and aren't used by CI anymore. It's a bit confusing having them
still around so let's be rid of them.
The implementation of painting for SVG text follows the same pattern
as the implementation of painting for SVG geometries. However, instead
of reusing the existing PaintableWithLines to draw text, a new class
called SVGTextPaintable is introduced. because everything that is
painted inside an SVG is expected to inherit from SVGGraphicsPaintable.
Therefore reusing the text painting from regular text nodes would
require significant refactoring.
These 4 fields were made `Atomic` in
c3f668a758, at which time these were still
accessed unserialized and TOCTOU bugs could happen. Later, in
8ed06ad814, we serialized access to these
fields in a number of helper methods, removing the need for `Atomic`.
The `<style>` element is allowed to be in the SVG namespace, so we now
support this element.
It has the same behaviour as the HTML namespace `<style>` element as
described in the spec.
"The semantics and processing of a ‘style’ and its attributes must be
the same as is defined for the HTML ‘style’ element."
I opened smolkling.webp in Photoshop, added a layer mask with a vertical
gradient, replaced the leftmost column with completely transparent
pixels (because the leftmost column is vertically predicted with the
horizontal filter too), and saved it as webp. That wasn't enough to
get a horizontal filter for the ALPH chunk though, so I also ran
cwebp \
-alpha_filter best \
smolkling.webp \
-o Tests/LibGfx/test-inputs/smolkling-vertical-alpha.webp
That did the trick.
I opened smolkling.webp in Photoshop, added a layer mask, and
scribbled a shape vaguely looking like the letter "C" on it.
I then saved it as a lossy webp and that was enough to end up
with filter method ¯\_(ツ)_/¯

(Looks like doing the same with a vertical or diagonal gradient
_also_ produces a webp file with filtering_method 1, i.e. horizontal.)
Prior to this commit, PropertyOwningCSSStyleDeclaration::serialized()
did not include custom properties, which lead to an incomplete
`cssRule.cssText` result.
This commit makes that class also serialize the custom properties and
place them before the regular properties in the rule text.
We began parsing SVG documents as HTML years ago in commit 05be648. This
was long before we had an XML parser, and actually violates the spec.
Since SVG documents have a MIME type of "image/svg+xml", the spec
mandates the document should be parsed as XML.
One impact here is that the SVG document is no longer "fixed" to include
<html>, <head>, and <body> tags. This will have prevented document.title
from detecting the document element is an SVG element.
Currently, if an SVG document is parsed, we enter the root <svg> element
twice - first when its node is appended, and then immediately after the
call to append its node. Prevent this by only ever entering nodes from
the appropriate location inside the call to append the node.
On macOS, CMake incorrectly tries to add and/or remove rpaths from files
that it has already processed when it performs installation. Setting the
rpaths during the build process ensures that they are only set once, and
as a bonus, makes installation slightly more performant.
Fixes#10055.
This broke in c2e24a2fa1 where the boot
drive was removed from `SERENITY_MACHINE`. We now add the boot drive to
the common Qemu arguments, so it gets included in the aarch64 run
configuration as well.
We were incorrectly returning a "specified size suggestion" for flex
items with a definite main size where that main size was also automatic.
This led to us incorrectly choosing 0 as the automatic minimum size for
that flex item, instead of its min-content size.
The PNP IDs data file was recently updated with an accidental duplicate
entry (HONOR Device Co., Ltd.). Rather than breaking everyone's build,
let's just ignore duplicates.
Generated iterator prototypes already have the IteratorPrototype as
their prototype, but we were incorrectly hijacking them and rerouting
to ObjectPrototype.
Regressed in cfe663435e.
