The refactor of the border painting mainly to handle:
1. Single border with minor border radius.
2. Different border widths and border colors joined situations.
This refactor only apply to solid border.
The main differece is to use Path.fill to paint each border,
not fill_rect anymore. There's a special case need to consider.
The Path.fill will leave shared edge blank between two borders.
To handle this, we decide to combine the borders with same color
to paint together.
When specifying either `background-position-x: right` or
`background-position-y: bottom` without an offset value no
EdgeStyleValue was created.
However, the spec says the offset should be optional.
Now, if you do not provide an offset, it creates the EdgeStyleValue
with a default offset of 0 pixels.
Works for fills and strokes (using colors, gradients, or patterns),
along with images.
fill_rect() has been updated to use fill_path(), which allows it to
easily transform the rect, and already supports opacity.

The translation to the bounding box location is handled by the gradient
transform, also doing it here breaks things.
This fixes the MDN <radialGradient> example.
The creator of this site is most definitely not going to enforce his
copyright, yes, but it's still a bad idea to keep around an unlicensed
copy of someone else's work. We no longer use it to 'test' anything, so
let's just remove it entirely.
bmpsuite on GitHub is licensed under the GPLv3:
https://github.com/jsummers/bmpsuite/blob/master/COPYING.txt
However, we did not "conspicuously and appropriately publish on each
copy an appropriate copyright notice", therefore we probably were in
violation with GPLv3 paragraph 4, "Conveying Verbatim Copies".
Let's just remove this entirely, because Ladybird can just access
the original pages instead.
At the time of writing, `bmpsuite.html` and the HTML response from the
linked URL are byte-identical.
This partially implements CSS-Animations-1 (though there are references
to CSS-Animations-2).
Current limitations:
- Multi-selector keyframes are not supported.
- Most animation properties are ignored.
- Timing functions are not applied.
- Non-absolute values are not interpolated unless the target is also of
the same non-absolute type (e.g. 10% -> 25%, but not 10% -> 20px).
- The JavaScript interface is left as an exercise for the next poor soul
looking at this code.
With those said, this commit implements:
- Interpolation for most common types
- Proper keyframe resolution (including the synthetic from-keyframe
containing the initial state)
- Properly driven animations, and proper style invalidation

Previously, `Heap` would store serialized data in blocks of 1024 bytes
regardless of the actual length. Data longer than 1024 bytes was
silently truncated causing database corruption.
This changes the heap storage to prefix every block with two new fields:
the total data size in bytes, and the next block to retrieve if the data
is longer than what can be stored inside a single block. By chaining
blocks together, we can store arbitrary amounts of data without needing
to change anything of the logic in the rest of LibSQL.
As part of these changes, the "free list" is also removed from the heap
awaiting an actual implementation: it was never used.
Note that this bumps the database version from 3 to 4, and as such
invalidates (deletes) any database opened with LibSQL that is not
version 4.
This is to allow testing autoplay, poster images, etc. without having to
stash local changes to the page. This also changes the URLs used on the
page to be relative to the page itself, to allow the page to load both
on Serenity and Lagom.
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 fixes a bug in the CSS Grid when there is a column and/or row gap,
as previously it would take the index of the incorrect column when
finding the `AvailableSize`.
There is a mild complication in the GridFormattingContext as the
OccupationGrid does not take into account the gap columns and rows that
later appear in the `Vector<TemporaryTrack>` columns and rows. The
PositionedBoxes are kind of a connection between the two, and so it's
now more explicit whether you would like to refer to a column by its
position taking into the gap columns/rows or not.
