e449e70e38 Simplify Changers interface
In fact having an extra parameter "bool cond" is no longer useful because it can
now always be emulated with a ternary operator:
	Changers dummy = cond ? do_change() : Changer();

ffb865d6e8 Clean up and fixes to fractions metrics and drawing
* Factor code for easier maintainance.

* Avoid computing metrics several times. This duplication explained the
  exponential blowup during the metrics phase for nested fractions (see
  b2b87330). This happened in particular when using lyxproofs which heavily uses
  nested \dfracs for on-screen drawing.

* Call MetricsBase::changeScript instead of MetricsBase::changeFrac for
  \nicefrac and \unitfrac.

a9eb87a89d Correct computation of math font size
Move math style to FontInfo and compute the font sizes for scriptstyle and
scriptscriptstyle according to standard proportions: 0.73 and 0.55.

This is simpler and more accurate. It also fixes the font size of
${\scriptscriptstyle {\textstyle A}}A$ which exposed the limitations of the
previous approach.

f643ae7007 Merge branch 'betterspacing'
The purpose of this branch is to improve the spacing in math equations

* do not use hardcoded pixel values, but math units that depend on
  zoom and dpi. This should be good for HiDPI systems.

* implement as much as possible the math typesetting algorithm
  described in Appendix G of the TeXbook.

One typical example of the spacing algorithm is that ``-a'' has no
spacing, contrary to ``a + b''. This reflects the unitary/binary
minus that will indeed happen in typeset output.

Together with the better character substitution that has already been
implemented by Guillaume, we get a nice improvement of mathed looks.

What makes this code complicated is that it handles macros properly:
the spacing inside the macro will depend on the values of the
arguments and the elements that are before and after the macro.

As a result, many definitions in lib/symbols are now just copy/pasted
from the relevant sty file. In particular, it is now possible to make
use of \mathrel, \mathbin, etc. macros to specify spacing.

This merge is a starting point. Remaining work includes

* proper handling of sub/superscript nucleus and of font-changing
  insets (as is done in the TeX algorithm).
* proper typesetting of fractions

Thanks to Guillaume for extensive testing.

7335ee8ea3 Cleanup of lib/symbols
Try as far as possible to use the same definitions as in the LaTeX files.

An example of that is the definition and subsequent use of \joinrel,
\relbar and \Relbar.

This is mostly Guillaume's work.

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.

f6df4e7985 Implement computation of spacing according to the TeXBook
This implements the relevant math typography rules described in the
Appendix G of the TeXbook. More precisely, for each atom

  + the class is computed by implementing rules 5 and 6 of Appendix G

  + the spacing is computed according to the table p. 170

This code is not used at this point.

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.

15fd79201e lib/unicodesymbols tests and fixes.
Test unicodesymbols for most supported input encodings with Kornel's addition to ctests.

Add required "forces" to unicodesymbols:
* utf8x does not support all characters supported by LyX
* several 8-bit encodings map characters to math-mode commands - force replacement in text-mode so that LyX can wrap them in \\ensuremath.

Fix a misalignment (wrong replacements) in the Cyrillic Unicode block.

Use \\mathscr for Mathematical Script characters in Mathematical Alphanumeric Characters (in line with the characters in other unicode blocks.

ad7e2435cf Fix display of some math symbols
* Fix spacing in lib/symbols after recent commits about math spacing, as well as
  older spacing issues (e.g. \Join).

* InsetMathKern now uses the same em value as other math length commands.

What is nice is that the kerning amount now matches the ones found in the
packages definition (modulo 10mu that lyx currently adds between relations).

fb264663d8 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.

Fixes bug #6570.

50ccbd2eab Always prefer breaking at word boundaries
An overlong word containing a hyphen could be broken anywhere, instead of after
the hyphen.

Example: compare the line breaking of

   aaaaa-aaaaa-aaaaa-aaaaa

with

   aaa aaaaa-aaaaa-aaaaa-aaaaa

(with a very narrow window)

This also improves Chinese text in some situations (#10299)

b30f8d3c4b 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.

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.

It turns out that Cursor::getFont() does not return a fully realized

5d85a42bf0 QString only uses UTF-16, not UCS-4
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.

3374b8548b 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.
