It turns out that Qt font selection via style name is broken on
Windows (QTBUG-101436). As we use our own style name for discriminating
our math fonts and applying proper kerning, we need a fallback method.
With this commit we check for the family name when the style name does
not match. In computing the kerning we also consider the right bearing
reported by the font instead of the width of the enclosing bounding box,
as this produces better results (see bug 13087).
Fixes#13087.

Each token could be delimited by quotation marks or not. The previous
regexes only considered this for two tokens and hence produced wrong
matches for cases such as
\Format gnuplot "gp, gnuplot, plt" "Gnuplot" "" "" "" "vector" "text/plain"
where the extension list wasn't parsed as a single token.

Previously, the tooltip was assigned during updateBuffer. But then
we could not determine the value for forward references.

There are several reasons to do it this way, among which is odd
behavior of the TOC filter if we put anything else there. This also
allows for filtering of the references themsevles in a natural way.
The change, I think, was really an unintended consequence of other
changes connected to showing formatted references in the work area.

This trivial patch makes scrolling-by-selection smoother by dividing
the step size and the time between steps by 8 when generating
synthetic events in work area.
The scrolling speed is unchanged, but the result is visually better.

\boxed{} is the only box in LaTeX that contains math. It is amusing
that the example file that we had for ticket #13609 should not have
been a problem since there is no reason to force <mtext> there.

This commit addresses two issues:
1/ the embarassing one: the member SetMode::old_text_level_ was
declared as bool instead of int. This means that is was definitely
not a proper backup variable!
2/ a robustness issue: replace two consecutive test for isTest() by a
boolean veriable that is used twice. This makes sure that <mrow>
cannot be output without the corresponding </mrow>.
Part of bug #13069.

Instead of generating code and parsing it to add <mtext>...</mtext> at
the right spots, this commit honors the text mode setting that was
already present in the codebase to generate it automatically.
This is the work of two helper methods in MathMLStream:
* beforeText() notices when the stream is in text mode and that a
<mtext> has not yet been generated. In this case it inserts it, so
that raw text can be emitted afterwards.
* beforeTag() checks whether a <mtext> needs to be closed at this
point, and does it if needed.
To make this work, the code now tracks the nesting level in the
stream, and compares it the what the level was when text mode has been
enabled using the SetMode helper function.
In order to avoid later bugs, member os() that allows to access the
underlying stream of MathMLStream is removed. This required many <<
operators to become friends of MathMLStream.
In InsetMathBox, rename splitAndWrapInMText() to mathmlizeHelper(),
which is not just a method that sets text mode inside a <mrow>
element.
In InsetMathFont and InsetMathHull, the explicit generation of nesting
in <mtext>...</mtext> can be removed now.
Fixes bug #13069.
(cherry picked from commit 216a6fb348)
This is preparatory work for fixing ticket #13069.
Remove direct accesses to the underlying stream of MathMLStream in
InsetMathChar, InsetMathSpecialChar, and in all << operators other
than MathMLStream << docstring. This will allow to add a hook later in
this operator.
Move default values of MathMLStream private members to their definition.
Get rid of line_ member, which is not used.

When using system colors it may happen (on windows 11 in particular)
that the background color is actually translucid. This is not
something we are prepared to handle and it creates ghosts on screen.
The fix is easy: the alpha channel of the colors is set to 255.
Fixes bug #13084.

The recordUndo() call is very wrong, since we may be inserting over a
selection covering several paragraphs (undo itself works at paragraph
granularity).
recordUndoSelection() is the right operation in this case. It is
equivalent to recordUndo() when there is no selection.
