b7c098c3fa Avoid blinking change tracking cur for math inset.
Since there is a margin above and below the inset, there is no problem
for putting it higher.

Fixes bug #11684.

f6282dfec7 Be careful before using buffer parameters in colAlign
Make InsetGrid::colAlign a normal method and make it check whether
buffer is valid before using it. This avoids crashes as we have seen
in 2.3.3 (see e.g. #11686).

There is still an assertion so that failure is noticeable before release.

0cba074ecf Better mechanism for setting cell height
When computing a cell metrics, it is now possible to specify whether it
is tight (at least as tall as 'x') or not (as tall as the max height of
the font).

Use this to make sure that grid insets have large enough cells. It
will probably appear that other cells needn't be tight. Currently, the
only cell which is known to be tight is the nucleus of the root inset.
Others should be examined one by one. It might be that the default of
MathData::metrics tight parameter should be `false'.

Fixes bug #11050.

546a6a2a31 Do not draw inactive math corners when they have mathbg color
By default, inactive math corners are invisible. In practice they are
annoying because they are visible when selecting text, and they can
also overwrite some parts of the equation.

The code in Inset::drawMarkers2, which is only used for maths, is
moved to InsetMathHull. Moreover, the inactive corners are not drawn
when they have the same color as the math background. A better way to
achieve this would be to set the color to transparent, but we do not
support this yet.

8be0ec0db5 Fix issue with change-tracked deleted display math
- If a display math not starting a new paragraph is deleted, the
  current \lyxdeleted macro (if any) must be closed and a new one
  started, otherwise the display math will be shifted up.

- Use \linewidth instead of \columnwidth because the former will adapt
  to the reduced horizontal width in list environments, avoiding shifting
  to the right the diplay math.

9fe8190364 Make "devel mode" configurable at run time
Traditionally LyX behaves differently when the directive DEVEL_VERSION
is defined at compile time. This covers
* more detailed description of current position in status bar
* the help files are open in read/write mode
* more detailed debug output in the View Source panel

This patch introduces the new function devel-mode-toggle that allows
to use devel mode in stable releases, and vice versa.

The information is saved in the session file. The default is to
disable devel mode.

Remove all traces of DEVEL_VERSION in autoconf and cmake

e30f3d76d2 Bulk cleanup/fix incorrect annotation at the end of namespaces.
This commit does a bulk fix of incorrect annotations (comments) at the
end of namespaces.

The commit was generated by initially running clang-format, and then
from the diff of the result extracting the hunks corresponding to
fixes of namespace comments. The changes being applied and all the
results have been manually reviewed. The source code successfully
builds on macOS.

Further details on the steps below, in case they're of interest to
someone else in the future.

1. Checkout a fresh and up to date version of src/

    git pull && git checkout -- src && git status src

2. Ensure there's a suitable .clang-format in place, i.e. with options
   to fix the comment at the end of namespaces, including:

    FixNamespaceComments:                           true
    SpacesBeforeTrailingComments:                   1

and that clang-format is >= 5.0.0, by doing e.g.:

    clang-format -dump-config | grep Comments:
    clang-format --version

3. Apply clang-format to the source:

    clang-format -i $(find src -name "*.cpp" -or -name "*.h")

4. Create and filter out hunks related to fixing the namespace

    git diff -U0 src > tmp.patch
    grepdiff '^} // namespace' --output-matching=hunk tmp.patch  > fix_namespace.patch

5. Filter out hunks corresponding to simple fixes into to a separate patch:

    pcregrep -M -e '^diff[^\n]+\nindex[^\n]+\n--- [^\n]+\n\+\+\+ [^\n]+\n'  \
        -e '^@@ -[0-9]+ \+[0-9]+ @@[^\n]*\n-\}[^\n]*\n\+\}[^\n]*\n'         \
        fix_namespace.patch > fix_namespace_simple.patch

6. Manually review the simple patch and then apply it, after first
   restoring the source.

    git checkout -- src
    patch -p1 < fix_namespace_simple.path

7. Manually review the (simple) changes and then stage the changes

    git diff src
    git add src

8. Again apply clang-format and filter out hunks related to any
   remaining fixes to the namespace, this time filter with more
   context. There will be fewer hunks as all the simple cases have
   already been handled:

    clang-format -i $(find src -name "*.cpp" -or -name "*.h")
    git diff src > tmp.patch
    grepdiff '^} // namespace' --output-matching=hunk tmp.patch  > fix_namespace2.patch

9. Manually review/edit the resulting patch file to remove hunks for files
   which need to be dealt with manually, noting the file names and
   line numbers. Then restore files to as before applying clang-format
   and apply the patch:

    git checkout src
    patch -p1 < fix_namespace2.patch

10. Manually fix the files noted in the previous step. Stage files,
    review changes and commit.

f1dd80f464 Proper GUI feedback for leqno option
With these changes, equation numbers are shown properly on screen.
When setting is default, we guess the side using these two rules

* ams(art|book) and siamltex classes are leqno by default. This is
  signalled because the classes provide "leqno" (in amsdefs.inc). If
  there are other classes that do this in output, the relevant classes
  should be updated.

* the language arabic_arabi also sets leqno by default. This is
  currently hardcoded for lack of a better idea.

Besides, a few bugs are fixed:
* use mathrm instead of mathbf for numbers metrics
* set spacing between maths and labels in inches

fa2dcd37a2 Show properly on screen "indented" maths.
This is done by two things:
1/ the equation returns LefAlign as display() value

2/ Inset::indent() return a value (in general 0) that should be added
   on the left (or right in rtl) of the inset when it is flushed.

The code that uses these values is in TextMetrics::computeRowMetrics.

89662a6852 Re-implement math markers logic.
The goal of this patch is to be able to properly remove the space
needed for markers in the case of insets that are inside macros and do
not need these markers. This was attempted at 9a9a6a8, but did not
work reliably.

To this end, the following simplifications are made:

* instead of drawing its own markers, each inset has a virtual method
  marker() which prescribes either NO_MARKER, MARKER (normal bottom
  marker) or MARKER2 (top and bottom marker). All explicit calls to
  (draw|metrics)Markers(|2) are removed.

* the space necessary for the markers is now counted in the
  before/above margins in the row structure. Therefore painting will
  not happen at (x + 1, y), but just (x,y).

* the methods drawDecoration are removed.

* the helper methods InsetMath::(draw|metrics)Markers(|2) are removed
  and replaced by a new function drawMarkers in MathRow.cpp.

Now the marker type is kept in the MathRow::Element object (and set to
NO_MARKER in not editable context) and the marker is accounted for in
MathRow::(metrics|draw).

Moreover, the extra pixel for the marker is taken on the before/After
space if possible. The marker will only require extra space when
before/after is 0.

See comment 168 of #8883 to understand what issues are fixed.

7f6f56f40a Get rid of Inset::setDimCache
This helper method is used to set the inset dimension cache at metrics
time. However this is already done by the metrics code itself
(MathRow::metrics, TextMetrics::redoParagraph), so that there is no
need to do this same work again in a different place.

Also, InsetPhantom::metrics is removed, since it does not do anything
interesting.

This commit comes with a mild risk attached (it might be that some of
these calls were useful after all!), but all of this is fixable.

02e82157ec Get rid of Inset::setPosCache
This helper method is used to set the inset position cache at drawing
time. However this is already done by the drawing code itself

Note that the inset positions are still set in InsetTabular::draw for
each cell.

these calls were useful after all!), but all of this is fixable.

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.

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.

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.

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).
