The setting of insets positions was done twice in updateMetrics.
When one of the paragraph is a huge branch, this can be very expensive.
This leads to a 17% improvement on updateMetrics time on a scrolling test.
Part of bug #12297
The idea of single par update is to try to re-break only the paragraph
containing the cursor (if this paragraph contains insets etc.,
re-breaking will recursively descend).
The existing single paragraph update mechanism was tailored to work
only at top level. Indeed changing a paragraph nested into an inset may
lead to larger changes.
This commit tries a rather naive approach that seems to work well: we
need a full redraw if either
1/ the height has changed
or
2/ the width has changed and it was equal to the text metrics width;
the goal is to catch the case of a one-row inset that grows with
its contents, but optimize the case of typing in a short paragraph
part of a larger inset.
NOTE: if only the height has changed, then it should be
possible to update all metrics at minimal cost. However,
since this is risky, we do not try that right now.
Part of bug #12297.
if the undo element we want to add only changes stuff that was already
modified by the previous one on undo stack (in the same group), then
skip it. There is nothing to gain in adding it to the stack.
The typical use case is when doing a search and replace in a large
document that does many replacements in each paragraph. In this case,
the same paragraph would be stored repeatedly.
Fixes bug #12564.
Qt::ImAnchorRectangle has only been introduced in Qt 5.7. Since it is
used to answer a query from the IM machinery, there is no need for
it with older Qt versions.

This was completely broken: the IDs have been escaped in the LyX file
(which they absolutely shouldn't) but not in all LaTeX output (which
they should).
\ was transformed very early to \textbackslash{}, but then the following
routines escaped braces in the string, so we wrongly ended up in
\textbackslash\{\} and "\{} in the output
This makes things much simpler.
But at least with the latest macos tools (Sonoma and XCode15) a bundle
refuses to run if it 's not signed properly.
Both issues are solved with the patch included and have now been tested
with Qt5.15 and Qt6.7.
For completeness: I've checked the font-emph shortcut issue and, as
reported in the ticket mentioned, ^CmdE works with Qt5.15 but not with
Qt6.7. However the sequence ^C E does work. I don't know whether this is
intended as a workaround for this issue or was already implemented.
