When blinking the caret, it looks like a cool idea to only update the
small rectangle containing the caret. Actually it is an awful idea, since
the paint event will paint some rows, and these rows will not be
properly painted outside of the small rectangle. Unfortunately, the
painter will skip those "painted" rows on next paint events.
This leads to painting errors that depend on the ordering of "real"
and "caret" paint events. This is the reason why they only appeared
with split screens.
Quote of the day: ``The real problem is that programmers have spent far
too much time worrying about efficiency in the wrong places and at the
wrong times; premature optimization is the root of all evil (or at
least most of it) in programming.''

Eventually, all overridden virtual methods should be marked properly.
Currently, clang only warns about those in classes that already use
override in at least one place (which was the case dor GuiApplication).
We need to bail out here early since otherwise the cache is prematurely
set to valid even if it is invalid with the bibliography environment.
The following checks (for timestamps of bib files) are only targeted
at bib(la)tex.
We used to need a hack to set the size of the layout combo, but
the code was changed in Qt 4.5 or so. Hence the appearance of this
bug in 2009. We can now just remove this hack, and all seems to
work correctly.
We need to load the master document before applying the params, since
otherwise the TOC reset (and other things) happen before the master
has been loaded (and set as parent).

Fix assertion when checking if change in selection
The check for the iterator being in the same paragraph as the end of
selection was incorrect, because paragraphs in different cells could
have the same pit. We now additionally condition on having the same
idx.

Fix crash when selecting text with changes
When selecting text, in some cases a DocIterator could be forwarded
to a (non-existant) paragraph after the end. The critical part of
this fix is to break the loop at the correct place. The following
are additional improvements:
- increase readability by defining a bool named "in_last_par"
- use cur.selectionEnd().pit() instead of cur.selectionEnd().paragraph().id()
- use it.lastpos() instead of it.paragraph().size()
This commit fixes a regression introduced by 23de5e5e, and reported
at #11204.

Only show Accept/Reject Change options if relevant
In the context menu for a selection, we now only show the options
"Accept Change" and "Reject Change" if there is actually a change in
the selection. Similarly, in the toolbar, the buttons are only
enabled when there is a change in the selection.
The backslash is the escape character used in our parser. Hence,
when used as a path separator on Windows, it has to be itself
escaped or the path enclosed in either double or single quotes.
Windows users are maybe trained to quote paths containing spaces
but not paths with backslashes. So, we automatically escape the
backslashes when they are not already enclosed in quotes.
This is related to the fix for #9158 and the caching of bibfile
information. On Windows, it is incredibly slow to run kpsewhich,
which we do to check where files actually are, so as to get info
about them (e.g., timestamps). So we have started to cache that
as a map. The map is supposed to be invalidated when various
things happen, but an oversight was causing it to be invalidated
on every cut operation. This is because cutting uses a temporary
Buffer, and the operations on it were affecting the *global* cache
of biblio file info. (It makes sense to have a global cache, since
these files are not document-specific.) Basically, we have to update
the list of bibfiles in that temporary Buffer---but that is one of
the things that invalidated the cache. The solution is only to
invalidate the cache if the list of bibfiles has actually changed
(a sensible idea anyway). The only time that will happen in the
temporary Buffer is when the copied information contains a BibTeX
inset. That should be fairly rare.

Fix segfault after deleting monitor
The boost signal was sent synchronously, and so made the Qt signal to be posted
in FileMonitor::changed after the boost signal returned, so after the sender was
possibly destroyed.
The solution is to make the boost signal asynchronous using the Qt event loop.
With Qt 5.11 at least, RtL text will be drawn RtL even when the
(undocumented) flag Qt::TextForceLeftToRight is applied to the
QTextLayout object. This creates selection issues for Hebrew text
marked as English.
The solution is to do the same as in breakAt_helper, that is prepend
the string with a direction override unicode character.
Doing this requires to introduce a TEXTLAYOUT_OFFSET constant that has
to be used wisely to account for this extra character.
As of LaTeX2e 2018, characters are made active earlier, which results
in new expansion problems.
Following a suggestion of Markus Kohm (pc) and the TL mailing list [1],
we embrace non-ASCII input paths in \detokenize. This relies on e-tex,
but I think we can assume this is nowadays available everywhere.
When deciding how to strike out deleted math in change-tracking
mode, differentiate only on begin-of-line or not, and not on
after-paragraph-break or not.
The assumption that a new paragraph is always started after a
float seems to be not true and was causing this bug.
