VALUES-4 defines the internal representation of `calc()` as a tree of
calculation nodes. ( https://www.w3.org/TR/css-values-4/#calc-internal )
VALUES-3 lacked any definition here, so we had our own ad-hoc
implementation based around the spec grammar. This commit replaces that
with CalculationNodes representing each possible node in the tree.
There are no intended functional changes, though we do now support
nested calc() which previously did not work. For example:
`width: calc( 42 * calc(3 + 7) );`
I have added an example of this to our test page.
A couple of the layout tests that used `calc()` now return values that
are 0.5px different from before. There's no visual difference, so I
have updated the tests to use the new results.
This makes it possible to do arithmetic on them without having to
resolve to their canonical unit, which often requires context
information that is not available until the last minute. For example, a
Length cannot be resolved to px without knowing the font size, parent
element's size, etc.
Only Length currently requires such context, but treating all these
types the same means that code that manipulates them does not need to
know or care if a new unit gets added that does require contextual
information.
Level 4 drops the limitations of what types can be a denominator, which
means `<calc-number-sum>`, `<calc-number-product>` and
`<calc-number-value>` all go away.
Upon opening already opened file, the cursor was previously not
set to the correct line and column. With this patch, it should
be correctly set.
Fixes a bug where ctrl+clicking a function declaration would not
jump to the line if the file containing the function is already
open.
This is not documented yet, but the preferred style is getting both
upfront instead of inlining various kinds of calls in places that use
the realm and vm.
Previously, the condition was reversed, so we would stop immediately on
a file that has at least one working chunk, and we would infinitely loop
on a file with no chunks.
read_webp_first_chunk() sensibly assumes that if decode_webp_header()
succeeds, there are at least sizeof(WebPFileHeader) bytes available.
But if the file size in the header was less than the size of the header,
decode_webp_header() would truncate the data to less than that and
happily report success. Now it no longer does that.

No behavior change.
(Well, technically mix() uses the other simple implementation of lerp
and the two have slightly different behavior if the arguments are of
very different magnitude and in various corner cases. But in practice,
for ICC profiles, it shouldn't matter. For a few profiles I tested, it
didn't have a measurable effect.)
By this point of time, we already have x86-64 support and have removed
i686 support too.
Since we are not the only OS project to remove 32-bit support entirely
and 64-bit computing is the norm for modern personal computers, there's
no need to explain this as it's obvious "why we are 64-bit only".
This is a remnant from when we didn't have a `read_value` and
`write_value` implementation for `AK::Endian` and instead used the
generic functions for reading a span of bytes. Now that we have a more
ergonomic alternative, remove the helper that is no longer needed.
PR #18166 introduced the ability to parse ECC certificates. If we
now fail here the reason is mostlikely something new and we should
prevent this rabbit hole from happening.
Some refactoring of our root ca loading process:
- Remove duplicate code
- Remove duplicate calls to `parse_root_ca`
- Load user imported certificates in Browser/RequestServer
TextEditor, HackStudio and SQLStudio now print the current line and
column number, as well as the number of currently selected words, with
thousands separators.
TextEditor also uses thousands seperators for the current word and
character count.
StartingStateHandler and SeekingStateHandler were declaring their own
`bool m_playing` fields (from previous code where there was no base
class).
In the case of SeekingStateHandler, this only made the logging wrong.
For StartingStateHandler, however, this meant that it was not using
the boolean passed as a parameter to the constructor to define the
state that would be transitioned to after the Starting state finished.
This meant that when the Stopping state replaced itself with the
Starting state, playback would not resume when Starting state exits.
Now that these are kind of working, lets add a layout test to prevent
future regressions :^)
This test is the same as the previous example (it is copied, though
that seems to have been done for other tests, e.g. Acid 1).
This is needed for hit testing the directional arrows on the Street
View office tour, and generally makes SVG hit testing more precise.
Note: The rough bounding box is hit test first, so this should not
be a load more overhead.
This also combines the viewbox mapping into the same transform and
reuses some code by using Path::copy_transformed() rather than manually
mapping each segment of the path.
