Add a new Color category to the Filter menu. Add the Grayscale
filter under Filter->Color to turn the selected layer to grey colors.
Created GrayscaleFilter.h. Modify Filter.h to allow filters
without parameters.
This patch changes the HTML formatting (where to put newlines, etc...)
to better match commonmark's test cases. This has minimal effect of the
correctness of our markdown implementation, but makes it easier to test.
Changes:
- Use <em> instead of <i>.
- Newline before end of code block.
- <hr /> instead of <hr>.
- Newline before first list item.
- Newline between lines of a paragraph.
- Trim whitespace on lines of paragraphs.
Tests passed: 33/652 -> 87/652
Applets and windows would like to be able to know when the applet
area has been resized. For example, this happens asynchronously after
an applet has been resized, so we cannot then rely on the applet area
position synchronously after resizing. This adds a new message
applet_area_rect_changed and associated Event AppletAreaRectChange,
and the appropriate virtual functions.
GNU ld sometimes generates zero-sized PT_LOAD headers when running with
the "-z separate-code" option. Let's not choke on such headers, we can
just ignore them and move along.
It's possible for the module to request too many locals, we now reject
such modules instead of trying to allocate space for them.
The value itself is chosen arbitrarily, so future tweaks _might_ be
necessary.

They're mostly used in literal random data, so it isn't like
there is a high demand for it, but it's cool to have more complete
implementation anyway. :^)
This improves the look of tabs and their focus rects. In particular, the
concept of a "text rect" is removed, and whatever tab content area is
left over after the icon and close button are added is used as the area
to draw the text into. This approach is simpler than having a separate
text rect.
Shades are colors darker than the color, tints are colors lighter.
This is helpful in places where we need a bunch of similar colors
with some small differences.
The common thin-cap button look (1px highlight, 2px shadow) looks nice
on regular buttons, but the scrollbar didn't feel quite right.
This patch adds 1px of offset to the highlight, giving it a thick-cap
look (which I have named Gfx::ButtonStyle::ThickCap) :^)
Once canonical extensions are implemented, the number of:
if (optional_string.has_value() {
builder.append('-');
builder.append(optional_string->to_lowercase_string());
}
Will be quite large. This commit just adds a helper lambda to handle
this pattern to prevent this function from becoming even more enormous.
This is preparatory work to read locale extensions. The parser currently
enforces that the entire string is consumed. But to parse extensions,
parse_unicode_locale_id() will need parse_unicode_language_id() to just
stop parsing on the first segment that does not match the language ID
grammar. It will also need to know where the parsing stopped. Both of
these needs are fulfilled by GenericLexer.
The caveat is that we can no longer simply split the parsed string on
separator characters. So parse_unicode_language_id() now operates as a
small state machine.
This is needed so all headers and files exist on disk, so that
the sonar cloud analyzer can find them when executing the compilation
commands contained in compile_commands.json, without actually building.

This commit adds a new process method to all Decoder subclasses which
do what to_utf8 used to do, and allows callers to customize the handling
of individiual UTF-8 code points through a callback. Decoder::to_utf8
now uses this API to generate a string via StringBuilder, preserving the
original behavior.
This always subtracted the glyph width of a space, despite isspace
also accepting newlines and a few other characters. It now also uses
AK/CharacterTypes.h. :^)
Non-printable characters should always have a width of 0. This is not
true for some characters like tab, but those can be exempted as the need
arises. Doing this here saves us from a bunch of checks in any place
that needs to figure out glyph widths for text which can contain
non-printable characters.
This more clearly expresses the purpose of this flag. Since only
CSS::WhiteSpace::Nowrap sets this value to false and it does not respect
linebreaks, this made the most sense as a flag name.
This commit refactors the text chunking algorithm used in
TextNode::ChunkIterator. The m_start_of_chunk member parameter has been
replaced with a local variable that's anchored to the current iterator
at the start of every next() call, and the algorithm is made a little
more clear by explicitly separating what can and cannot peek into the
next character during iteration.
