2acc4fc54c Improve spacing of BOX elements
Tweak the algorithm so that a BOX math row element can have some
spacing. To this end, MathRow::before/after do not look at the type of
an element for deciding when to skip it, but rather to its math class.

In the new setting, the spacing algorithm works on all elements, but
skips the MC_UNKNOWN elements as if they were not present. As a
consequence, the two element types BEGIN and END have been replaced by
a single DUMMY (they can be recognized from their class).

To simply the code, add a new `mclass' argument to the
MathRow::Element constructor (default is MC_UNKNOWN).

0f15dcc698 Rewrite handling of macro nesting in math rows
Macro nesting is now recorded into the macro inset itself. This allows
the ArgumentProxy inset to determine whether it is editable or not by
looking at its macro.

Remove code in the metrics and draw methods of ArgumentProxy: this
code is AFAICS not active anymore, since arguments are linearized into
math rows.

Use Changer idiom to change locally the values of MecticsInfo::base.macro_nesting.

e8f480e7c2 Fix display and output of math macros with optional arguments
This is a long standing issue, present since the new math macros
inception in version 1.6. It manifests as a display issue when a
macro with optional arguments appears in the optional argument of
another macro. In this case the display is messed up and it is
difficult, if not impossible, changing the arguments as they do not
appear on screen as related to a specific macro instance. It also
manifests as latex errors when compiling, even if the latex output
is formally correct, due to limitations of the xargs package used
to output the macros. Most probably, both aspects have the same
root cause, as simply enclosing in braces the macro and its
parameters solves both issues. However, when reloading a document,
lyx strips the outer braces enclosing a macro argument, thus
frustrating this possible workaround.

This commit solves the display issue by correctly accounting for
macros with optional arguments nested in the argument of another
macro, and circumvents the xargs package limitations causing errors
by enclosing in braces the macros with optional arguments appearing
in the argument of an outer macro when they are output. This means
that when loading an old document with such macros and saving it
again, the macro representation is updated and will have these
additional braces. However, as such braces are stripped by lyx on
loading, there is no risk that they accumulate.

c3e33b765e Match the font in MathMacro::metrics with the font in MathMacro::draw
This fixes the "bad keming" of math ERT (in fact wrong metrics) which recently
was worsened by InsetMathChar substitutions and their MathClass spacing.

Also fix a small inefficiency: always prefer:

  Changer dummy = (currentMode() == TEXT_MODE)
    ? pi.base.font.changeShape(UP_SHAPE) : Changer();

over:

  Changer dummy = pi.base.font.changeShape((currentMode() == TEXT_MODE)
    ? UP_SHAPE : pi.base.font.shape());

The former only records and restores a value when the condition is satisfied,
and does not cost anything otherwise.

  exponential blowup during the metrics phase for nested fractions (see

9a9a6a8c8f Skip drawing of markers in non-editable math data
There is no reason to reserve pixel space in macros replacement text,
which is not editable. This makes macros more compact and eases the
writing of lib/symbols.

* introduce new InsetMath::drawMarkers and friends that do nothing
  when nested inside a macro. This required to move macro_nesting
  inside MetricsBase, and to pass MetricsInfo & to metricsMarkers.

* keep track of nesting when drawing rows or macros.

f3f9b083d1 Only display a blue rectangle for editable empty insets
Empty insets should use a minimal amount of space, especially when
they are part of a built-in macro in lib/symbols.

With this change, blue rectangles signal actually editable places.
Empty macros in editable data are shown as grey boxes, but they do not
appear when further nested.

This is done by adding a new type BOX of MathRow::Element object and a
MetricsInfo::macro_nesting that keeps track of macros (and is reset to
0 in editable macro arguments).

bf56e2c8e1 Set correctly the spacing between atoms in MathData
* new MathRow class which contains the description of a MathData
  object in terms of math class and spacing

  + macros and their arguments used in the MathData object are
    linearized (replaced with their contents) so that all math insets
    are typeset as a string together. To this end, we introduce a
    method addToMathRow to InsetMath and MathData. This method allows
    to linearize recursively a MathData object.

  + It is then necessary to set manually the dimension and position of
    the macros and arguments.

  + the class class and spacing are computed using the MathClass helpers.

  The MathRow data is cached in the MathData object in a bufferview-dependent
  way (different dpi for different screens).

* delegate most of the work MathData::metrics/draw to MathRow metrics/draw.

  The case of draw is trickier, since many draw() methods rely on their
  metrics without any spacing added.

361bd53bc3 Introduce the notion of math class
This done according to the TeXbook. This class replaces the individual
isMathXXX() methods. The mathClass() method (currently unused) is
provided for the following insets:

 * InsetMathChar (with a revised list of affected characters)
 * InsetMathSymbol: the class is given by the `extra' field
   Operators defined in lib/symbols (e.g. \log) are MC_OP
 * InsetMathFrac is MC_INNER (except nicefrac and units)
 * InsetDelimiters is MC_INNER
 * InsetStackrel is MC_REL
 * The class of InsetScript is the class of the last element of its
   nucleus (yes, it is a hack, but doing it right is more work).

Remove the explicit spacing that was done in the different insets. The spacing
will be reintroduced properly in a forthcoming commit.

34ae9dc7f2 Avoid dataloss with \multicolumn
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.

e3c3719643 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.

8d5899aaf3 Fortify math insets against ulem commands
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.

129459a71b Take into account font changes when striking out display math formulas
Font changes are brought inside the \lyxdeleted macro, just before
outputting the latex code for the math inset. The inset writes a
signature before itself and this is checked by \lyxsout for recognizing
a display math. So, the font changes confuse \lyxsout, which also
swallows the first macro at the very start of \lyxdeleted. The result
is that the font changing command is not seen by latex and \sout is also
used to further strike out the formula already striked out by tikz.
This commit makes sure that the expected signature actually appears
just after the opening brace of \lyxdeleted. It also accounts for a
paragraph break occurring just before the math inset, in order to not
introduce too much vertical space, which is noticeable when using
larger font sizes.

c1bfaa5c76 Fix latex error when change-tracked deleted display math starts a new paragraph
LaTeX refuses to break a line when it is empty. But we have to start
a new line here, otherwise the whole displayed equation would be
typeset as it were inline with previous content. The solution is to
put a zero-length space just before the line break. Moreover, this
is the right thing to do, as it simulates the extra space that is
normally added in this circumstance.

261e7ae9ce Strike out (in the output) deleted display math with track-changes
Showing deleted display math by enabling "Show Changes in Output" was
only possible with dvi (through dvipost). Although LyX strikes out
such formulas on screen, it was impossible obtaining an output
directly using pdflatex (or other engines producing pdf) because
ulem cannot cope with display math material and gives errors.
The solution is to strike out by ourselves such deleted formulas.
I took into account several options. One of them would produce
an output similar to dvipost (which strikes out each element), but
would have required much more changes in the output routines.
Eventually, I opted for using tikz, which gives a more clean
output (as it requires to simply adding a preamble and a postamble
to the latex code of any displayed math, instead of a mark up
tailored to each particular math construct). The look of the pdf
output is similar to the way LyX strikes out the equations on screen.

The math macros system is quite complex. Macros are updated during

time, which also happens when the table of contents is updated.
Moreover, in order to circumvent a possible missing update, when
a math macro is detected we try to avoid using the sym_ member
of the MacroData class, as it may contain bogus values.

a6be519a81 Fix data loss with [ in first cell of aligned
If the first character in the first cell of an aligned math environment is
'[', and the environment does not use top or bottom vertical alignment,
then LyX did write the '[' unprotected so that it got misinterpreted as
optional argument, both when reading the .lyx file in LyX and when reading
the .tex file in LaTeX => data loss!
The fix is to output an empty optional argument in this case, which is
interpreted as default alignment both by LyX and LaTeX. It would also be
possible to output \[ in the first cell instead, but this would be more
difficult to implement.

This is the well known file locking problem: The TempFile class keeps the
created file locked for the own process, and this prevents the CAS to read it.

4b64aaf4ce This patch does two closely related things.
The main thing it does is integrate mouse-modifiers into the
FuncRequest machinery. Previously, these had to be passed
separately, which led to some ugly function signatures.

There was also an unnecessary form of the constructor, which
can now be removed.

No change of behavior is intended.

14fa2c7162 Remove using directives from headers
The only exceptions are:

- The purpose of the header is to drag in the used symbol, e.g. unique_ptr.h
- The used symbol is inside a class or a namespace other than lyx

The reason for this is that global 'using' statements effectively forbid to
use the used symbols in any other namespace in the whole program, since simply
adding or removing an #include of the corresponding header subtly changes the
name lookup. The namespace lyx is sort of global, so it should not have these
statements either.

3c6f2427c3 Tweak output from maxima
Maxima uses \it as a markup for multiletter variables. However,
it has been reported that since texlive 2016 using \it in math
mode produces an error, even though I was not able to reproduce.
Anyway, this can be avoided by replacing the old-style construct
"{\it ...}" with the new-style one "\mathit{...}".
The problem has also been reported upstream:
https://sourceforge.net/p/maxima/bugs/3181/
but this workaround will hold whatever the resolution.

b2b8733096 Remove a conversion to_utf8() inside FontSetChanger
This requires to change many docstrings into std::strings. The logic behind that
is that they represent a fixed set of math fonts, and therefore “string” means
here “poor man's enum” rather than text (this is consistent with MetricsBase).

Profiling of scrolling inside a document over macro-instensive areas:

Before the patch:
  44,1% BufferView::updateMetrics()
   -> 34,8% InsetMathHull::metrics()
     -> 9,8% FontSetChanger::FontSetChanger()
  28,4% BufferView::draw()

After the patch:
  35,3% BufferView::updateMetrics()
   -> 27,2% InsetMathHull::metrics
     -> 0,4% FontSetChanger::FontSetChanger()
  47,5% BufferView::draw()

FontSetChanger::FontSetChanger() is made 41x less expensive (with reference
BV::draw()) just by removing this conversion. The remaining 0,4% could be
squished by replacing the strings with a proper enum, but this is premature. Of
course, this only treats the symptoms: there is no good reason that this
function is called 45500 times over the time of 40 repaints.

e2bc7ffae3 RefChanger
RefChanger temporarily assigns a value to a non-const reference of any
kind. RefChanger provides a flexible and uniform generalisation of the various
scope guards previously derived from the old Changer class in MetricsInfo.h.

As before, a temporary assignment lasts as long as the Changer object lives. But
the new Changer is movable. In particular, contorsions are no longer needed to
change a private field. Special code can be moved into the appropriate classes,
and it is no longer necessary to create a new class for each specific use.

Syntax change:

   FontSetChanger dummy(mi.base, value);
-> Changer dummy = mi.base.changeFontSet(value);

New function for generating arbitrary Changers:

  Changer dummy = make_change(ref, val, condition);

Bugfix:

* Fix the display of \displaystyle{\substack{\frac{xyz}{}}} (missing style
  change).

c0ce79452f Introduce proper integer rounding function
This fixes a failing unit test with 32bit gcc 4.9.3 and -O2 optimization:
It computed 9953 instead of 9954 for Length::inPixels() of value 2342.
The reason for this is probably different rounding behaviour caused by storing
the unrounded value in a processor register (uses 80bit accuracy) vs. writing
it back to memory (uses 64bit accuracy). The unrounded value is very close to
9953.5 (which is not representable as an exact IEEE floating point value).

Apart from that, having a proper function for rounding makes the code more
readable, and has the nice side effect to make Length::inPB() work for
negative lengths as well.

Guillaume Munch
c9f7ce0a7a New LFUN tabular-feature (#9794)
The tabular-features LFUN was merged with "inset-modify tabular" when
simplifying the tabular dialog at b5049e7. This choice later indirectly caused a
few regressions (#7308, #9794).

I reintroduce tabular-feature to allow more flexibility for user
commands, whereas "inset-modify tabular" is now reserved for the tabular
dialog. In particular, inset-modify tabular is no longer caught by math grid
insets. The name tabular-feature is kept to avoid renaming icons.

Known issues:

* After successfully applying a tabular command, the cursor is truncated to the
  table.

* Note that the tabular dialog still has similar issues that are inherited from
  the achitecture of the dialog menu. For instance the pref change can be
  mis-dispatched to an inset inside a cell and cause an error, for instance:

    Lexer.cpp (934): Missing 'Note'-tag in InsetNote::string2params. Got
    tabular instead. Line: 0

  Maybe the inset-modify LFUN should be modified to treat commands coming from
  the wrong dialog (by checking the type) as unknown and undispatched so that
  the parent can get it. In that case a non AtPoint variant of inset-modify
  could be reintroduced in order to generalise tabular-feature. See:

bb344452c8 Consistency of ellipses across the UI
Use the function support:truncateWithEllipsis() to shorten a docstring with
... at the end. Actually we use U+2026 HORIZONTAL ELLIPSIS instead of "..." when
automatically shortening strings. This is to be consistent with Qt's own
truncation and is much nicer on the screen.

This includes the bugs #9575 and #9572 regarding broken text elision in the
outliner.

Known issues (non-regressions):

* TocBackend::updateItem() should be rewritten to update all TOCs. (#8386)

* "..." should be replaced with … everywhere else on the interface (including
  translation strings).

* We should prefer to rely on QFontMetrics::elidedText() to truncate strings
  with an ellipsis whenever possible, or an equivalent for the buffer view
  dependent on the font metrics. See the warning in src/support/lstrings.h.

d5a5fbb8ee Enhancements and bugfixes to the TOCs
* New TOC "math-macro". This means that math macros can now be accessed in the
  outline pane in their order of appearance or in alphabetical order, and can be
  searched using the filter.

* Lists of floats now show subfloats deeper in the navigation menu

* The arbitrary 30 element cut-off after which nothing is shown except "Open
  Navigator..." is removed. Menus now have no limit in size, so Qt may display
  them scrollable. In exchange, we always show "Open outliner..." at the
  beginning. I tested for performance issues with a rather complex document and
  it is fine; but this does not exclude corner cases with lots of TOC entries of
  a certain kind. If necessary, populating the navigation sub-menu should be
  delayed like the main menu.

* Elements that do not contribute to the output (e.g. in a note, a disabled
  branch) are now preceded with a symbol indicating this status. (The machinery
  was already there; I wonder why it was not implemented already.) I have chosen
  U+274E NEGATIVE SQUARED CROSS MARK.

* Fix the contextual menus in the outliner (bug introduced at 94e992c5).

* Toc item now move to the caption when present, but first center on the float,
  to prevent the situation where the caption is at the top of the screen and the
  contents of the float is off-screen above the caption.
  (Internally, the action of the toc items can now be customised)

after Undo, etc. in a document with math macros since 1.6.0. (Regression at
6aa54673 and 12314897)

I do not know the purpose of these calls, but the selection code has been worked
on since, and I cannot produce undesired behaviour after removing
them.

94e992c5ed Better construction of the TOC for floats and captions
We introduce TocBuilder for building TOCs that take into account both float
insets and their captions.

* Floats without caption are shown with their content.

* Floats with a caption are shown with their caption, but clicking the entry now
  correctly moves to the float and not to the caption.

* Subsequent captions produce additional entries in the TOC.

* Figures and subfigures are correctly ordered in the outliner.

* New TOC "senseless" for captions appearing alone (a bit like broken references
are still displayed in the menu and outliner).

* Disable LFUN_CAPTION_INSERT if there is already a caption in a listing

Known issues:

* Inconsistent output for includes located inside floats

* We should record the end of the float in addition of the beginning for a more
  accurate cursor -> outliner entry conversion

61145265fc Math commands used in text mode now always use the current selection as contents
(#9762)

* fixes a bug where this was already the expected behaviour of
  math-subscript and math-superscript but failed.

* corrects the behaviour where if there is \newcommand in the
  selection, then a corresponding macro template is introduced
  instead of a math inset.

  * fixes a bug where math-display, math-subscript and math-supscript
    would also introduce such a macro template in a way unrelated to
    their function. Now it only happens with math-mode without
    arguments.

  * fixes a bug where a text that does not denote a macro definition,
    e.g. "aaa\newcommandaaa", would produce \invalidmacro.

699a6db9fa Add some missing member variable initializations
These were all found by cppcheck. Even in constructors that are there "only
because of std containers" the class should be initialized correctly. You can
never know whether such an object does not get used, and then a nice crash
caused by dereferencing a NULL-pointer is better than undefined behaviour.
