Qt assumes that ascent+descent is the bounding height of the
text, but for historical reasons, the ascent for some fonts
will not contain the diacritics. On Windows, the preference
is to use data from the OS/2 table which were explicitly
invented to work around this, but on other platforms we
are not respecting this table. This causes a text layout
that looks fine on Windows to have overlapping characters
on e.g. macOS.
To make vertical metrics (ascent, descent, leading) consistent
across all platforms, we don't blindly trust the values we get
from the underlying font system, but apply in the following order:
1. If OS/2 table exists and USE_TYPO_METRICS flag is set, we
use the typo metrics from OS/2 table
2. If OS/2 table exists and USE_TYPO_METRICS flag is not set,
we use winAscent/winDescent from OS/2 and the line gap from
HHEA table.
3. If no OS/2 table exists, we try to get ascent, descent and
line gap from the HHEA table.
4. If the HHEA table does not exist (not an SFNT), we fall back
to the system-provided metrics. (on macOS, we know the
system-provided metrics will match the data in HHEA, so we
skip parsing that table and use the data from CoreText if
there is no OS/2 table).

This patch adds a publicly callable qt6_add_plugin() API to create
plugins. This API is meant to cover cases such as the plugandpaint
example.
This patch also renames qt_add_plugin to qt_internal_add_plugin in order
to avoid clashes with the public API. To avoid breaking the existing
projects, a compatibility wrapper function is enabled by default unless
QT_DISABLE_QT_ADD_PLUGIN_COMPATIBILITY is specified.

Amends 402efef57b. The original patch
has a problem, namely that it directly calls QPlatformWindow::requestUpdate()
instead of going through QWindow::requestUpdate(). As there is a chance that
an update gets scheduled between the creation of the QPlatformWindow and this
extra, optional invocation of requestUpdate() at the end of QWindow::create(),
this becomes quite unsafe because QPlatformWindow, unlike QWindow, is not
graceful: it will just assert if there is a pending update still.
Solve the whole thing by storing the updateRequestPending flag of QWindowPrivate,
then resetting it, and then going through the safe, public
QWindow::requestUpdate() when our copy of the flag says so.

If the widget whose line control we are has its own locale setting,
then we should use that rather than the default UI layout direction.
Instead, the client of the QWidgetLineControl needs to handle the case
where auto-detection of the text direction can't be done based on the
content of the line control.
Fortunately, QWidget's handling of text direction handles setting to
auto gracefully as unsetting, on which it consults the parent widget
to set a sensible default.

Consider a negated feature config value like the following:
qt_feature_config("foo" QMAKE_PUBLIC_QT_CONFIG NEGATE)
If this feature was disabled, it would turn up in both,
enabled_features and disabled_features of module .pri files.
Also, QT_CONFIG would contain foo.
Expected however is that QT_CONFIG contains no-foo, and only
disabled_features contains foo.
Fix this by prepending a "no_" prefix to the value, similar to the
"no-" prefix in the qmake build. The qt_correct_config function was
adjusted to recognize "no_foo" and translate it to the qmakeish
"no-foo" config value.
Config values that start with "no_" but do not correspond to a feature
are left untouched. You can still have values like
"no_valley_too_deep" or "no_mountain_too_high".
