Previously this stored the position of each visual line break, meaning
that all the text would always be painted. By storing each visual
line's Utf32View, we can skip over parts of the text, such as for code
folding.
This only becomes a problem with folding, since arbitrary lines may be
invisible, meaning we try to apply a span for an invisible line N, on
line N+X instead, causing occasional crashes.
This check means we can remove the loop that skips spans occurring at
the end of the line.
This commit moves the implementation of getopt into AK, and converts its
API to understand and use StringView instead of char*.
Everything else is caught in the crossfire of making
Option::accept_value() take a StringView instead of a char const*.
With this, we must now pass a Span<StringView> to ArgsParser::parse(),
applications using LibMain are unaffected, but anything not using that
or taking its own argc/argv has to construct a Vector<StringView> for
this method.
That is, return ErrorOr<int>, handle fallible ops with TRY() and accept
a Main::Arguments.
Note that we do not populate the argc/argv members of Main::Arguments,
so all accesses have to go through .strings.
This currently allocates in .parse(), but that's better than making the
caller do the exact same before passing us the values.
Note that this is only temporary to aid in conversion, a future commit
will remove this and switch to requiring the users to allocate the
vector instead.
With the GC heap conversion, the functionality of legacy platform
objects was broken. This is because the generated implementation of one
of them was used for all of them, removing functionality such as
deletion.
This re-adds all functionality, where questions such as "does the
object support indexed properties?" is instead answered by virtual
functions instead of by the IDL generator checking the presence of
certain keywords/attributes.
The name "initial containing block" was wrong for this, as it doesn't
correspond to the HTML element, and that's specifically what it's
supposed to do! :^)
Before, the shading of the Presenter icons was the wrong way round and
the external contrast was not as good as it could be. This has been
rectified and the icons are now light on the left- and dark on the
right-side. Also, they now use the same gray colors as other system
icons, making them sit much more nicely together, and have been
generally improved.
Using char causes bytes equal to or over 0x80 to be treated as a
negative value and produce incorrect results when implicitly casting to
u32.
For example, `atob` in LibWeb uses this decoder to convert non-ASCII
values to UTF-8, but non-ASCII values are >= 0x80 and thus produces
incorrect results in such cases:
```js
Uint8Array.from(atob("u660"), c => c.charCodeAt(0));
```
This used to produce [253, 253, 253] instead of [187, 174, 180].

Defining it as a direct property causes it to have no getter/setter
function, which causes an empty Optional crash when attempting to
access such getter on a cross-origin iframe.
Fixes amazon.com crashing on this particular crash.
Turns out that, if we don't use functions that ensure reading until the
very end of the buffer, we only end up getting the very beginning of
samples and fill the rest with uninitialized data.
While at it, make sure that we read the data that is little endian as a
LittleEndian.
We are currently setting the physical mouse position to the visual
cursor content location. In a line containing only a multi-code point
emoji, this would set the cursor to column 1 rather than however many
code points there are.
