Make insertInset use a temporary cut-and-paste area.
This is a long wanted feature, although it does not go all the way to
fix #6604 (private-cut/private-paste).
Additionally, it fixes a crash that can happen when using undefined
branches. This is done by making the action when pasting unknown
branches configurable.

On-screen justification: stretch in proportion with the em, up to a limit
1) Distinguish expanding characters from separators, to fit with Qt's notion of
expanding character which comes from the Unicode std. CountExpanders() is moved
to FontMetrics to fix a discrepancy with the duplicate implementation from 598f7e4a.
2) Make these expanders stretch on-screen proportionally to the em of the font.
If a row mixes large and small text, LyX let us see which spaces are set in the
bigger font.
3) Now that the stretch is defined in ems, add a limit such that an expander
never stretches more than 1.5em to avoid weird and hard to read justified lines.
4) Add a return boolean to setSeparatorExtraWidth for future use.
When \multicolumn{ncol}{align}{content} is parsed and the ncol
parameter is not a numeric value, this parameter is swallowed
and replaced with '1'. Hence, if the file is subsequently saved
a dataloss would occur. With this commit, \multicolumn is not
interpreted when ncol is not a numeric value and is left as is.
It turns out that Cursor::getFont() does not return a fully realized
font in some cases. This patch uses real_current_font instead, which
seems better anyway.
I suspect that all uses of getFont() should be removed, but this is
not code that I know well.
This means that, when a string contains high-plane Unicode characters,
the length of a docstring and the corresponding QString will be
different: Qt will encode these characters using several 16bit
characters.
We have additionally to take into account QTBUG-25536, which implies
that sometimes qstring_to_ucs4(toqstr(s)) !=s. It is not clear whether
this bug can be a problem in other places.
Fix usage of multiple varieties of the same polyglossia language.
1. We must always output all (diverging) options, including
default options; if not, default options might get overwritten.
2. Do not output options in \setotherlanguage, since we might have
multiple "other languages" varieties from the same language (such
as naustrian, nswissgerman). And the options are output for the
language switches anyway.
Hence, LaTeXFeatures::getPolyglossiaLanguages() does not have to record
varieties. This was not done correctly anyway, since the map allowed
for one entry per language only.
Don't print useless messages while parsing math macros
Math macros can be displayed on screen by providing a different
representation than the one used for latex output. This representation
is actually used by lyx even while it is being updated. This leads to
printing useless error messages on the terminal. For example, a macro
parameter has to be entered as \#1 and, if the macro is already used in
a math inset, lyx prints on terminal the error message "Math parse error:
missing token after \\" as soon as one hits the \ key, followed by
"MathMacroArgument::MathMacroArgument: wrong Argument id: -48" as soon as
one hits the # key. So, this is not a useful information and simply
clutters the terminal output. On the other hand, the input is sanitized
even if one stops input after hitting either \ or #, so that no further
messages are issued. Hence, those error messages are simply pointless.
Factor out common code used to underline/strike out math
Also use the exact amount of vertical space TeX adds after a
math display (instead of 1ex) for vertically shifting the box.
We have to use \belowdisplayshortskip here, instead of
\belowdisplayskip, because the math formula is typeset by alone
in a box, and thus there is no following line.
* with Qt5, it seems that QFontMetrics::width does not return the
correct value for some Arabic text; this patch uses QTextLayout
instead to compute a string width
* Likewise, the undocumented layout flags TextForceRightToLeft and
TextForceLeftToRight do not work with Arabic text; this patch uses
unicode override characters instead.
It might be that the two issues are related. In any case, they do not
happen with latin text where right-to-left direction is enforced. And
they do not happen with Qt4.
Additionally, remove some dead code in GuiFontMetrics::pos2x().
Correctly track ulem commands with change tracking
LyX assumes that everything in \lyxdeleted is struck out by ulem
and increases the corresponding counter. However, deleted display
math material is struck out using tikz. As we also take into
account the deletion of underlined display math (in order to
properly position such material vertically), we have to take
care that the count is correct.
No newline is written after \begin{document}, such that
the afterParbreak method would return false. This misleads
the code that outputs a display math in an ulem command
to emit a newline command instead of \noindent, causing
latex errors. This occurs only if the math is at the very
start of a document, without anything before it.

support for Amharic, Asturian, Kannada and Khmer
- fileformat change
- I could not update the tex2lyx test files because of bug #10440
- maybe the lyx2lyx routine could be improved but since a document can also begin with another layout than "Standard" I could not use the lyx2lyx function put_cmd_in_ert
It should be now possible underlining or striking out any kind
of math inset containing any math construct indigestible to ulem.
While this was already possible for inline math insets, they could
have break if an aligned environment was used, for example.
This is now possible also for diplay math. Even if this can be
nonsensical and not visually perfect, at least no latex errors
should be generated if one tries to.
