These used to be enabled in `serenity_compile_options.cmake` for
Serenity builds and were removed in 9b05fb98. This is a slightly more
conservative subset of those, with ones that are enabled by default
omitted.
This should prevent our code quality regressing in the long run.
Trying to build VulkanLoader from source is a giant headache of
unnecessary packages. Every modern distro has vulkan packages, let's
depend on those instead of trying to build something for both wayland
and X11.
Skia now uses GPU-accelerated painting on Linux if Vulkan is available.
Most of the performance gain is currently negated by reading the GPU
backend back into RAM to pass it to the Browser process. In the future,
this could be improved by sharing GPU-allocated memory across the
Browser and WebContent processes.
GPU painter that uses AccelGfx is slower and way less complete compared
to both default Gfx::Painter and Skia painter. It does not make much
sense to keep it, considering Skia painter already uses Metal backend on
macOS by default and there is an option to enable GPU-accelerated
backend on linux.
This large commit also refactors LibWebView's process handling to use
a top-level Application class that uses a new WebView::Process class to
encapsulate the IPC-centric nature of each helper process.
We currently build debug and release versions of vcpkg dependencies. We
will most commonly only need the release version, so let's default to
that to approximately halve our dependency build time.
VP9 continues to function, but this also allows AV1 to be decoded. With
this commit, H.264 is still non-functional, as the decoder requires
some extra initial data from the track definition in the Matroska file.
For SerenityOS, we parse emoji metadata from the UCD to learn emoji
groups, subgroups, names, etc. We used this information only in the
emoji picker dialog. It is entirely unused within Ladybird.
This removes our dependence on the UCD emoji file, as we no longer
need any of its information. All we need to know is the file path to
our custom emoji, which we get from Meta/emoji-file-list.txt.
There are a couple of differences here due to using ICU:
1. Titlecasing behaves slightly differently. We previously transformed
"123dollars" to "123Dollars", as we would use word segmentation to
split a string into words, then transform the first cased character
to titlecase. ICU doesn't go quite that far, and leaves the string
as "123dollars". While this is a behavior change, the only user of
this API is the `text-transform: capitalize;` CSS rule, and we now
match the behavior of other browsers.
2. There isn't an API to compare strings with case insensitivity without
allocating case-folded strings for both the left- and right-hand-side
strings. Our implementation was previously allocation-free; however,
in a benchmark, ICU is still ~1.4x faster.
This changes the Sanitizer configs to build all the vcpkg dependencies
with our specified CFLAGS and CXXFLAGS for ASAN and UBSAN.
Unfortunately, we can't yet enable actually compiling them with
sanitizers enabled, because this causes test failures that need to be
investigated.
This uses ICU for all of the Intl.PluralRules prototypes, which lets us
remove all data from our plural rules generator.
Plural rules depend directly on internal data from the number formatter,
so rather than creating a separate Locale::PluralRules class (which will
make accessing that data awkward), this adds plural rules APIs to the
existing Locale::NumberFormat.
