Carl Schwan ab2f4ef8fa QTextDocument: Add support for responsive images
Add support for the max-width css attribute in image. This allows images
to be responsive: it adapts their size to the size of the QTextDocument
so that they never grow bigger than the QTextDocument pageSize.

This is implemented for the image handler used in QTextEdit and other
QtWidget text related classes.

[ChangeLog][QtGui][CSS] The max-width style can now be applied to
<img/> to set the maximum width in pixels or percentage.

Eskil Abrahamsen Blomfeldt 1593b1f6d6 Introduce optional smarter font merging with ContextFontMerging
This introduces an optional, slightly more expensive approach
to font merging which takes the full string into account,
instead of just going character by character.

This addresses the issue that you may sometimes get multiple fonts
to cover one string of text in a single language. With Chinese,
this is especially an issue because many fonts will only support
parts of the very large character set.

The new algorithm detects if the string was incompletely covered
by the font and tries the fallback fonts in order to find the best
match. This is obviously more expensive, especially if no perfect
match is found and we have to check all the fallbacks in the list,
but it is opt-in and only enabled if the ContextFontMerging flag
is set.

Eskil Abrahamsen Blomfeldt cba15d99f0 Add API to provide user-defined fallback fonts
When depending on Qt's font merging for providing glyphs for certain
languages, there are currently some drawbacks. For one, you will
typically get a system font which might not fit together with the
main font of the application.

In addition, you might get some glyphs from one font and other from
another (typically for Chinese where the character sets are so large
that fonts will often only implement parts).

And finally, you may get the wrong glyphs for writing systems with
regional differences, if your application is e.g. written in Japanese
and then run on a Chinese system, you might get Chinese versions of
characters which are shared between the languages.

Without language-based font matching in Qt, there's no silver bullet
for fixing this. This patch introduces API which makes it possible for
users to provide the solution themselves, either by selecting
application-provided fonts as fallbacks for certain scripts or by
hardcoding system fonts for a specific language.

[ChangeLog][Fonts] Added API to override default fallback font
families for specific scripts.

Shawn Rutledge 0281005a71 QTextMarkdownWriter: escape all backslashes
A literal backslash needs to be doubled so that the parser doesn't treat
it as escaping the following character when the markdown is read back.
In ca4774131b we tried to limit it to
backslashes that were not already escaped. In case someone really needs
a longer series of backslashes, it's more correct to escape them all;
but this comes with the risk that if they do not get un-escaped by the
markdown parser in some scenario, repeated round-trip saving and loading
could multiply them excessively. So we also add a lot of tests to try
to verify that this is safe.

Shawn Rutledge bf8167c5fc tst_QTextMarkdownWriter: test both ways of setting font characteristics
We have explicit QFont properties, and QTextFormat::setProperty().
Setting FontFixedPitch doesn't necessarily affect the view (QTextEdit or
Qt Quick Text/TextEdit); and setting the font to the one we get from
QFontDatabase::systemFont(QFontDatabase::FixedFont) is also unreliable,
because the "monospace" fallback might actually be proportional.
QTextMarkdownWriter checks for both to decide whether to use backticks;
so markdown writing works if an editor UI makes the format monospace
both ways to be safe. But in the opposite case that the main font is
actually a monospace font, it's always been broken.

The rest of the QTextCharFormat properties are generally working, to
the extent that they are applicable to Markdown. But we lacked explicit
test coverage: so far we were just reading Markdown or HTML and writing
Markdown to test the writer.

Also amend an old comment about writing underlines: writing was always
possible, and since f5c7799f59 reading is
supported too. So the underline support is symmetric (except that we
don't heed the QTextDocument::MarkdownFeatures argument to the writer
ctor: we probably should do that some day).

Shawn Rutledge bffddc6a99 Extract and re-write "front matter" in markdown documents
It's increasingly common for YAML to be used as metadata in front of
markdown documents. md4c does not handle this, so we need to remove
it ahead of time, lest md4c misinterpret it as heading text or so.

The --- fences are expected to be consistent regardless of the format of
what's between them, and the yaml (or whatever) parser does not need to
see them. So we remove them while reading, and QTextMarkdownWriter
writes them around the front matter if there is any.

If your application needs to parse this "front matter", just call
qtd->metaInformation(QTextDocument::FrontMatter).toUtf8() and feed that
to some parser that you've linked in, such as yaml-cpp.

Since YAML is used with GitHub Docs, we consider this feature to be part
of the GitHub dialect:
https://docs.github.com/en/contributing/writing-for-github-docs/using-yaml-frontmatter

[ChangeLog][QtGui][Text] Markdown "front matter" (usually YAML) is now
extracted during parsing (GitHub dialect) and can be retrieved from
QTextDocument::metaInformation(FrontMatter). QTextMarkdownWriter also
writes front matter (if any) to the output.

3. The DirectWrite font engine was not loading kerning pairs
   from the font, like the other engines (omission which was
   detected by the test)
4. Turning off antialiasing does not work with DirectWrite, so
   we fall back to GDI for this.

   was not supported.

Shawn Rutledge 3bd4c1b670 Avoid detection of heading in tst_QTextMarkdownImporter::thematicBreaks
In md4c 0.4.8, three or more hyphens immediately after text were seen as
a thematic break:

some text
---

But in 0.5.1 it makes the text into an H2 heading (even though this
style of heading would normally have the text fully "underlined" with
hyphens). The CommonMark spec 0.30 says

  If a line of dashes that meets the above conditions for being a
  thematic break could also be interpreted as the underline of a setext
  heading, the interpretation as a setext heading takes precedence.
  Thus, for example, this is a setext heading, not a paragraph followed
  by a thematic break:

  https://spec.commonmark.org/0.30/#example-59

So the new behavior seems more correct. But rather than testing so
deeply, just disambiguate by adding a newline, since Qt may be expected
to work with various versions of md4c, and such minor behavior
differences are not expected to come up often in practice.

QTextMarkdownWriter already adds a newline when writing such markdown.

Volker Hilsheimer 66b5803ab9 Adapt QRawFont to use QFont::Tag
Add an overload for fontTable (we can't deprecate the const char *
overload as it will be used for string literals, even if the tag-
overload would work), and use the tag type in the test instead of
QByteArray.

Volker Hilsheimer bde443801f QFont: add a tag type for features and other advanced properties
Instead of overloads and generic string literals with runtime checks,
use a dedicated Tag type for specifying the font feature. The Tag type
can only be instantiated with a string literal of exactly 4 characters
(plus the terminating null)l; longer or shorter literals result in a
compile time error.

Constructing a Tag from any other string type is possible through the
named fromString constructor, in which case we can only check the length
and warn at runtime.

The type's API is almost completely constexpr so that we can use it to
calculate e.g. enum values.

Eskil Abrahamsen Blomfeldt a890df0283 coretext: Support variable application fonts
Named instances of variable application fonts are exposed
automatically through CTFontManagerCreateFontDescriptorsFromData()
(and also for the URL equivalent).

The main change here is just to call this instead of the overload
which only returns the first font.

Note that this also updates the test: This is because the conversion
from CoreText normalized weight values to TTF values is not 100%.
In the CoreText code, we map Heavy (0.56) to ExtraBold, but ExtraBold
gets converted to 0.6, which is closer to the CoreText value for Black
(0.62).

To avoid hitting this inconsistency, the QtExtraBold has been changed
to Black weight instead, which resolves to the same on all platforms.

Shawn Rutledge 801b8304fb Add QTextDocument* constructor argument to QTextMarkdownImporter
QTextMarkdownImporter::import() took a QTD* as if it would be ok to
reuse one instance of QTextMarkdownImporter for repeated importing into
different documents; but in practice, we never do that: in fact it's
usually a short-lived, stack-allocated object, as in
 QTextMarkdownImporter(&doc, QTMI::DialectGitHub).import(input);
So it's less clumsy internally to require the document be provided to
the constructor: that way a QTextCursor can be constructed immediately
too, as part of the importer object rather than separately on the heap.

This is private API, unused outside qtbase.

Ahmad Samir 8e0281a8be tests/auto/: port Q_FOREACH to ranged-for, local const containers
These are local containers that are either:
- Already const and didn't need Q_FOREACH to begin with
- Can be simply made const, just by adding const keyword

In one case the unittest checked that the container's size is 1, so use
list.first() instead of a for-loop.

In files where Q_FOREACH isn't used any more, remove
"#undef QT_NO_FOREACH". Also remove those files from NO_PCH_SOURCES.

Drive-by changes:
- Remove parenthesis from one-line for-loops
- Make the for-loop variable a const& where a copy isn't needed

Marc Mutz 11d6932560 Mark all of Qt as free of Q_FOREACH, except where it isn't
The density of Q_FOREACH uses in this and some other modules is still
extremely high, too high for anyone to tackle in a short amount of
time. Even if they're not concentrated in just a few TUs, we need to
make progress on a global QT_NO_FOREACH default, so grab the nettle
and stick to our strategy:

Mark the whole of Qt with QT_NO_FOREACH, to prevent new uses from
creeping in, and whitelist the affected TUs by #undef'ing
QT_NO_FOREACH locally, at the top of each file. For TUs that are part
of a larger executable, this requires these files to be compiled
separately, so add them to NO_PCH_SOURCES (which implies
NO_UNITY_BUILD_SOURCES, too).

In tst_qglobal.cpp and tst_qcollections.cpp change the comment on the
#undef QT_NO_FOREACH to indicate that these actually test the macro.

Marc Mutz f2f8820073 tests: port assorted trivial uses of Q_FOREACH to ranged for loops
All of these fall into the trivial category: loops over (readily made)
const local containers. As such, they cannot possibly depend on the
safety copy that Q_FOREACH performs, so are safe to port as-is to
ranged for loops.

There may be more where these came from, but these were the ones that
stood out as immediately obvious when scanning the 100s of uses in
qtbase, so I preferred to directly fix them over white-listing their
files with QT_NO_FOREACH (which still may be necessary for some files,
as this patch may not port all uses in that file).
