Now that LengthStyleValue never contains `auto`, IdentifierStyleValue is
the only type that can hold an identifier. This lets us remove a couple
of virtual methods from StyleValue.
I've kept `has_auto()` and `to_identifier()` for convenience, but they
are now simple non-virtual methods.
Previously, whether trying to parse a `<length>` or `<dimension>`, we
would accept `auto` and produce a `LengthStyleValue` from it. This
would fool the `property_accepts_value()` into allowing `auto` where it
does not belong, if the property did accept lengths.
Of the few places in the parser that called `parse_dimension_value()` or
`parse_length()`, none of them were expecting it to accept `auto`, so
this fixes those too. :^)
Currently, `property_accepts_value()` always returns `true` if the
property is a shorthand. (This is a bug, and should actually be fixed
properly at some point...) This means that all identifiers are caught
here, including `auto`, which should be handled by the `flex-basis`
branch instead.
This works currently because `auto` is a LengthStyleValue, but that's
about to change!
This code assumed that `auto` was always stored as a LengthStyleValue,
which will not be true in the next commit. (And was not a safe
assumption to make anyway.)
This is a tiny bit messy because:
- The spec says we should expand this to `flex: <flex-grow> 1 0`
- All major engines expand it to `flex: <flex-grow> 1 0%`

This should not affect boot times on qemu, as that does not use
dynamic transfer delays in its adma code path.
On real hardware this could potentially double the data throughput,
decreasing load times.
While at it, pass the `--3way` option to give the user something to work
with. Otherwise, Git will just prepare the commit metadata and nothing
else. Note that this has a relatively low chance of working, since the
recorded blob hashes aren't known to a freshly imported repository.
This is far from perfect, but let's at least make an attempt at laying
out <svg> when encountering it inside another <svg>.
This makes https://awesomekling.substack.com actually load and render
instead of asserting. :^)
Negative accumulation on the right-hand side of the accumulation bitmap
would wrap around to the left, causing a negative start for certain
lines which resulted in horizontal streaks of lower alpha values.
Prevent this by not writing out of bounds :^)
Fixes#18394
An oval approximated by quadratic bezier curves ended up with 2048 line
segments when rasterized to a bitmap of around 35 by 35 pixels, which
seems a bit much. :^)
By increasing the tolerance by an order of magnitude, that same oval is
now split up into 512 line segments, which is still more than enough for
a high quality render.
This adds a checkbox to enable autoplay on all websites (disabled by
default) and a website list to enable autoplay on individual websites
(set to file:// URLs only by default).
The spec defines a Permissions Policy to control some browser behaviors
on a per-origin basis. Management of these permissions live in their own
spec: https://w3c.github.io/webappsec-permissions-policy/
This implements a somewhat ad-hoc Permissions Policy for autoplaying
media elements. We will need to implement the entire policy spec for
this to be more general.
Alphabetically sort everything (namespaces and forward declarations
within namespaces), and de-duplicate repeated namespaces (namely the
Web namespace appeared twice).
For the most part no behavior change, except that we now pass
-Wno-implicit-const-int-float-conversion and -Wno-literal-suffix
only to clang and gcc each in both lagom and serenity builds,
while we previously passed them to both in lagom builds (and
passed them to one each in serenity builds). The former is
a clang flag, the latter a gcc flag, but since we also use
-Wno-unknown-warning-option it doesn't really matter.
Previously SpinBox did not update on return or changes to the editor.
The widget had to lose focus or be manually incremented. This lets
the editor update on return and now always displays the most recent
clamped value. set_value_from_current_text() will also be useful to
programmatically set SpinBox within layouts whose default buttons
consume return key presses.
