This change fixes problem that y position of blocks with
clearance might not include border_top and padding_top
by changing `place_block_level_element_in_normal_flow_vertically`
to accept y position without `border_box_top` and adding it
on the last step when clearance is already taken in account.

Since AK can't refer to LibUnicode directly, the strategy here is that
if you need case transformations, you can link LibUnicode and receive
them. If you try to use either of these methods without linking it, then
you'll of course get a linker error (note we don't do any fallbacks to
e.g. ASCII case transformations). If you don't need these methods, you
don't have to link LibUnicode.
DeprecatedFlyString relies heavily on DeprecatedString's StringImpl, so
let's rename it to A) match the name of DeprecatedString, B) write a new
FlyString class that is tied to String.
Previously, we would assume that all standard 14 fonts use a
TrueTypeFont dictionary. Now we render them in Type1Font as well,
given that it doesn't contain a PostScript font program.
While this subtable ID is supposed to be deprecated, it is used heavily
in PDF files.
It supports mapping one or two-byte values, with quite a large list of
encodings to tell you which one to expect.
For our use case, we ignore this encoding ID and just pick the first
subtable with this platform ID. Unsupported encodings will get caught
by Subtable::glyph_id_for_code_point() anyway.
By setting this hint, you indicate to OOPWV that the content inside will
scale itself to the viewport size. In such situations, it's fine for
OOPWV to reuse a scaled version of an outdated backing store while the
view is being resized.
Introduce `table_box()` function that returns table formatting
context root box casted to `TableBox` similar to how it's done
in other formatting contexts like `root()` in BFC and
`flex_container` in FFC. And replace `context_box()` calls
in TFC with calls to `table_box()`.
It is incorrect to skip anonymous block containers without
line boxes during block auto height calculation because there
might be table roots wrapped in anonymous table boxes after fixup
and their height should be taken in account so leaving just
condition to skip child boxes which margins are "collapsed
through" (`border_box_height() == 0`) sufficient to skip
anonymous blocks without lines but still consider table wrappers.
According to table fixup algorithm:
https://www.w3.org/TR/css-tables-3/#fixup-algorithm
around every table-root should be generated anonymous
box wrapper.
Also this patch implements important part of CSS 2.2
spec that is currently not present in CSS Tables 3
spec draft: https://www.w3.org/TR/CSS22/tables.html#model
that portion of computed properties should be moved
from table-root to table wrapper box. Without having
this part implemented height of absolutely positioned
table with `height: auto` won't be computed correctly.
Fixup rule that table roots need to be wrapped in anonymous
block boxes need to be implemeted instead of having `TableBox`
inherited from `BlockContainer`.
This trims the input bytes to the profile size stored in the file.
Alternatively, we could reject files where the stored size doesn't
match the handed in size. But ICC profiles can be embedded in other
files, and those could conceivably pad the ICC profile data some.
When using this mode on an AbstractScrollWidget, it was not honoring the
related "scrollbars enabled" setting.
If scrollbars are disabled, they should never be made visible by the
"unnecessary scrollbars" logic.
This produces a (truly) null DeprecatedString, which is not expected to
occur by CharacterData (where this string ends up).
Simply pass an "empty" DeprecatedString manually instead.
The `deprecated_format` helper is a thin wrapper to map results from
AK::vformat to a throw completion. This will let us try to throw on OOM
conditions rather than just blowing up.
Note it's called `deprecated_format` as we will likely end up adding a
method named just `format` to return `ThrowCompletionOr<String>`, when
we begin the migration from DeprecatedString->String for LibJS.
