The object replacement character (U+FFFC) is used to represent
inline objects such as images in rich-text. To enable this,
we have special handling of it in QTextEngine. For classes
where inline images are not supported, it will just be hidden
from the visual text, which is unexpected.
Instead of always special-casing it, we make this dependent
on whether the document layout has registered any object handlers.
If they have not, then there will be no visual representation of
the object, and it is better to show the glyph for it.
For anything based on QTextDocument, there will always be the
image handler, so U+FFFC will still have special handling there,
but for non-rich labels and plain text editors the glyph will
be shown instead.
Note that there was also a bug in QLineEdit, where the object
replacement character was always replaced by a space. This was
introduced in 2007, in a patch which replaced a !ch.isPrint()
with a check for "the most obvious non-printable characters"
to reduce the number of characters that were not shown. However,
U+FFFC is a printable character and would thus not have been
filtered by the !isPrint() condition, so I think this was a
mistake at the time. However, due to the special-casing of
the character in Qt, it would not have had any effect until
now.
This also changes the QTextLayout::cursorToXForInlineObject()
test to actually test proper inline objects, as this was
previously using a hack which depended on the inline object
code to be used even for plain QTextLayouts with no handlers
for these.
[ChangeLog][Text] The object replacement character (U+FFFC)
is now only filtered out in rich text controls, where they
represent inline objects. In other controls, its glyphs will
be shown as with other text.

Variant-selectors are special unicode symbols which are used to
modify glyph selection for the preceding character. For instance,
a regular symbol could be turned into a color emoji using VS16,
the emoji variation selector. In order for this to work, however,
the font that handles the selector has to handle the full pair of
characters, so that it can apply the correct substitution rules.
One specific example of this was on macOS, where an airplane
symbol + VS16 would match the symbol to the default UI font but
the VS16 to the emoji font. Since there string provided for the
emoji font did not have any preceding character for VS16, we just
ignored it.
To improve on this, we now detect variation selectors that have
been matched to different font engines than the preceding
character. When such a case occurs, we check if the selector font
also supports the preceding character, and if it does, we keep
the pair together and use the same font for both.
[ChangeLog][QtGui][Text] Fix some cases where a variation-selector
character would be ignored in font selection and the correct
variant of a character would thus not be selected.

This amends fccd419dd6.
If Harfbuzz failed on one of the items in a string and returned
zero glyphs, then we would exit the shaping loop. The mentioned
change fixed a crash related to this when the ignored character
was the only character in the string, but it occurred in a
subitem of a longer string, then we would return and fail to
lay out the rest of the string.
This popped up recently because an update to Harfbuzz has caused
it to return zero glyphs when applying the Apple emoji font to
an isolated variant character (see bug report). When we matched
the symbol to the main font and only the variant character to
the emoji font, we would get in this situation, and end up
exiting the shaping early.

This introduces a way to trace each entry in the glyph index
array to a specific index in the original text passed to
QTextLayout, as well as a convenience function to access
the original string from the QGlyphRun.
The index information is stored in the logClusters array internally
in Qt, but it contains the inverse information: For each
character in the output string, it contains an index into the
glyph array. In order to get the string indexes for each glyph,
which makes a lot more sense in the context of the QGlyphRun
API, we need to do a little search to construct the data.
To avoid adding unnecessary allocations, we make the new APIs
opt-in. If you do not specify anything, you will only get the
glyph indexes and glyph positions as before. However, you
can now specify exactly which parts of the layout to extract
using an optional flags parameter.
This also adds a manual test which can be very handy to
visualize QTextLayouts and how they are split into QGlyphRuns.

In Qt 5 style sheets, objects could be selected by an enum-type property
using the integer value of the enum value, e.g
QToolButton[popupMode="1"] { ... }
In Qt 6, the the new meta type system and QVariant implementation enabled
QVariant::toString to return the string representation of the enum value
instead for a property containing an enum. Since QStyleSheetStyle's
attribute matching is string based, this breaks the Qt 5 style selector,
and QCSS code instead needs to use e.g.
QToolButton[popupMode=MenuButtonPopup] { ... }
While the new syntax is arguably preferable, this is an unintentional
change that silently breaks style sheet code (no error or warning at
compile- or run-time).
To support Qt 5-style selectors, we have to change the StyleSelector
interface of the QCssParser API so that we can pass through what type
of value the attribute extractor should return; if an integer string "1"
is provided, then we need to compare the enum integer value; if the
string provided does not represent a number, then we need to compare the
name of the enum value.
Since the pure virtual attribute() method that needs to be implemented
to extract the attribute value of the node is implemented in modules
outside qtbase, add a second virtual method that takes the entire
QCss::AttributeSelector, which includes the value to match. Extractor
implementations can use it to evaluate which type of data to return for
an exact match. The default implementation calls the old attribute()
method so that existing StyleSelector implementations continue to work.
Make the respective change in the QStyleSheetStyleSelector, and simplify
the surrounding code. Adjust other StyleSelector implemnentations in
qtbase. As a drive-by, remove the superfluous virtual declaration from
those overrides.
Once submodules are adjusted to override this virtual function instead
of the (now no longer pure) virtual attribute() method, that method can
be removed.
