When using Qt stuff in breakAt, it may happen that the row is broken
after an hyphen (whereas the old code would only consider spaces).
The fact that we abuse the Row::right_boundary() property to detect when
a row should be flushed broke justification when a row is cut at an
hyphen.
Fix this by introducing a new Row::flushed() property and set it as needed.

The code that tries to decide whether it is worth splitting a given
text row element had a shortcoming: it did not take into account the
left margin of the new row that would be created.
The problem is that this left margin is not the same as the left
margin of the current row, because there can be for example
indentation effects.
To fix this problem, we pass the amount of available space on the
next row as a parameter of Row::shortenIfNeeded.
Note that there is no need to care about RtL row elements at this
point, since the bidi algorithm will be applied to the row
subsequently.

They are shown on screen by arrow or pilcrow symbol and cause a line break.
They are still not handled in LaTeX output, though.

Whenever an argument delimiter is used inside the argument, the argument
needs to be grouped, that is
\cites({text (text) text})
or
\cite[{text [text] text}]
This fixes the original case reported in #2751 which is independent
from the general issue that the pre- and postnote field take literal
code.
It seems that QTextLayout does not handle properly a single character
with 0 width. This breaks drawing of things like \not.
No status line needed as this amends 24648404.
PLEASE work in branch for the doc files. There is no reason not to release improved manuals with the next bugfix release. Only new features of LyX 2.3 are only for master.
When cloning InsetExternal, the tempname_ member of InsetExternalParams
has yet to be initialized. So, trying to remove it causes the warning
"QFile::remove: Empty or null file name".

The QTextLayout handling is terribly slow on Qt 4.8.7, but some
caching has been added in Qt5 that makes it much faster. For some
reason, it is not that slow with Qt 4.8.1.
Caches are introduced for the three following methods
* width(doctring), controlled by CACHE_METRICS_WIDTH. This cache already
existed, but the code has been cleaned up
* getTextLayout, controlled by CACHE_METRICS_QTEXTLAYOUT (disabled by
default on Qt5, which does its own caching). This is used for pos2x
and x2pos and now for drawing of text too. The previous code used a
trivial caching scheme of the last used QTextLayout, but now they
are properly kept in a QCache. Moreover, the cacheEnabled() property
is enabled for these QTextLayout object (not sure what this does).
* breakAt, controlled by CACHE_METRICS_BREAKAT. This is the only user
of QTextLayout which did not have some kind of caching already.
For some weird reasons related to Argument-dependent look-up, the
qHash(docstring) function has to be defined in std namespace, since
lyx::docstring is actually std::basic_string<wchar_t>.

Subject: [PATCH] Add "Swap & Reverse" to math delimiter dialog
When "Keep matched" is unchecked, a button becomes enabled to "Swap &
Reverse" the left and right delimiters. This is expected to be of use
with line-wrapped equations featuring one or more set of delimiters that
break across the lines. When "Keep matched" is checked, the button is
visible but disabled.
The most common use case is expected to be the user entering a pair of
unmatched delimiters on the first line of an equation (e.g., "(" and
"(None)"), entering the inner text, going to the next line, and
inserting the opposite set of delimiters (e.g., "(None)" and ")").
This button will negate the need to find the correct corresponding
combination. However, it relies on the dialog's memory of the previous
unmatched set.
This change addresses Ticket #10457
-----------
Modifications by spitz to the original patch:
* Only enable the button if an unmatched pair is selected
* Consider l7n when locating the string "(None)"
* Add an accelerator and a tooltip to the dialog
* Simplify the code a bit
The XHTML entries were added in the wrong field, if they are given we need
extra xhtml requires. The order is inconsistent, there are discussions on the
list about that but for now I'll use the existing order to fix the export tests.
The format of the lib/symbols file does not support "" for empty strings.
One would have to use x for fields that are not set (this is a hack), but
actually we know how to fill the extra field.
