Note: We keep locale parsing and syntactic validation as-is. ECMA-402
places additional restrictions on locales above what is required by the
Unicode spec. ICU doesn't provide methods that let us easily check those
restrictions, whereas LibLocale does. Other browsers also implement
their own validators here.
This introduces a locale cache to re-use parsed locale data and various
related structures (not doing so has a non-negligible performance impact
on Intl tests).
The existing APIs for canonicalization and display names are pretty
intertwined, so they must both be adapted at once here. The results of
canonicalization are slightly different on some edge cases. But the
changed results are actually now aligned with Chrome and Safari.
Rather than removing LibLocale entirely, we will use it as a wrapper
around ICU (which has some C-like interfaces, and uses UTF-16 for its
string types). Using ICU will provide better web compatibility overall,
and will let us implement features we were previously unable to (e.g.
Intl.Collator requires data that is not in the JSON export of the CLDR).
This fixes https://html5test.com/ as previously an exception was being
thrown after trying to access this attribute which would then result in
a popup about the test failing (and none of the test results being
shown).
This AO can be used instead of CreateReadableStream in cases where we
need to set up a newly allocated ReadableStream before initialization of
said ReadableStream, i.e. ReadableStream is captured by lambdas in an
uninitialized state.
If we get a suggestion from fontconfig, we try those fonts first, before
falling back on the hard coded list of known suitable fonts for each
generic family.
The spec doesn't explicitly forbid calling this when the document
doesn't have a node navigable, so let's handle that situation gracefully
by just returning an empty list of ancestors.
I hit this VERIFY somewhere on the web, but I don't know how to
reproduce it.
This saves us the trouble of maintaining our own implementation,
and instantly brings us to full WOFF2 feature parity with others.

Before this change we were painting inner shadows lying outside of
viewport.
Improves painting performance on Github and Twitter where this command
is used a lot.
Also add a vcpkg command to ladybird.sh to ensure that vcpkg is setup,
and use a local binary cache for vcpkg build and install media to
avoid cluttering $XDG_CACHE_HOME.
This struct had all members in CSSPixels and DevicePixels, but only the
latter are needed for painting.
Shrinks PaintOuterBoxShadowParams from 144 bytes to 72 bytes.
