fa4fc6fc4d Avoid some caret ghosts
When the caret is at end of row, if may happen that it is drawn after
the end of the row. In this case caret blinking will not work
properly. This patch extends the row background on the left and right
by Inset::TEXT_TO_INSET_OFFSET. This is only a hack that will not work
if the caret has a ridiculous width like 6.

Additionally, introduce some (disabled) debug code that numbers the
rows on screen by painting order.

Finally, make the code that detects whether the caret was in a given
row more precise (take boundary into account).

Fixes (mostly, see above) bug #10797.

4ecbff0019 Allow multiple calls to processUpdateFlags before redraw
The goal of this commit is to ensure that a processUpdateFlags call
that requires no redraw will not override a previous one that did
require a redraw.

To this end, the semantics of the flag argument is now different: its
value is now OR'ed with a private update_flags_ variable. This
variable is only reset after the buffer view has actually been
redrawn.

A new Update::ForceRedraw flag has been added. It requires a full
redraw but no metrics computation. It is not used in the main code
(yet), but avoids to compute metrics repeatedly in consecutive
processUpdateFlags calls.

The process is now as follows:
- if flags is just None, return immediately, there is nothing to do.
- the Force flag is honored (full metrics computation) and replaced
  with ForceDraw.
- the FitCursor flag is honored and removed from the flags.
- the SinglePar update is added if ForceDraw is not in flags and only
  the current par has been modified.

The remaining flags are only then added to the BufferView update
flags, and the update strategy is computed for the next paint event.

Finally the dubious call to updateMacros in updateMetrics has been
removed for performance reasons.

6bd158dcba Improve the logic of caret repainting
For some reason the existing code only considered the bottom row that
contained the cursor. There is no need for that, and actually it
caused painting problems in nested insets.

Tweak the logic of repaint_caret_row_ a bit: there is no need for
repainting when there is currently no caret on screen.

9bb41f0943 Update insets position in cache in more cases
This patch makes sure that, every time a ParagraphMetrics has its
position set, the inset positions for the insets held by this
paragraph are remembered too.

This is complementary to BufferView::updatePosCache, but I do not have
hard evidence that this is required other than to increase robustness.
It may help in some cases when scrolling the document (scrollbar,
cursor up/down, page up/down).

ef1d502070 Fix caret painting
The trick is to remember in BufferView what has been done at the
previous draw, so that the row that contained the caret can be
repainted if needed.

To this end, add an argument paint_caret to BufferView, although
painting the caret is not the job of the BufferView (at this point).

BufferView::needRepaint will act as an interface with
TextMetrics::drawParagraph to know whether the painting of a given
row should be forced.

Currently everything is done at the top row level, so that, if the
caret is in a large table, the whole table will have to be repainted.
It is not clear yet that this is necessary.

d222e0f48e three-stage drawing: add a nodraw stage
Normally the two stages of drawing are
1/ compute metrics of insets/rows/paragraphs/mathrow...
2/ draw the elements and cache their positions

Now the three stages are
1/ metrics
2/ nodraw: do not draw the elements, but cache their position
3/ draw the elements (and store again their position; it does not
   seems to hurt performance).

Revive the NullPainter: this replaces the setDrawingEnabled mechanism
with a painter that does nothing. The advantage is that updatePosCache
(renamed from setPosCache) does not need anymore to be invoked from
the frontend.

updatePosCache (the nodraw stage) is called at the end of
BufferView::updateMetrics.

e040ccb0e8 Collapsable -> Collapsible (part 1)
The current spelling is not strictly wrong, but flagged as unusual or
historical by some authorities. It is also found fault with many
spell checkers. Thus we decided to move to the more standard "-ible"
form once and for all.

See #10678 for discussion

This part only covers the usage in comments and the like. More to follow.

This will all also all be backported to 2.3.x, for the sake of backwards
compatibility (cherry-picking).

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.

8aaec85c8c Now Inset::dimension is only an access to cache
Up to now Inset::dimension was either a helper function to access
CoordCache, or... something else. This created problems to properly
use it.

In particular, the definition of InsetText::dimension created problems
for child classes. Removing this definition (actually renaming it to
dimensionHelper) allows to streamline the code.

b099d9ae15 Fix height of cursor inside insets
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.

Fixes bug #10478.

8f86ee74cd Make sure that math macros are updated at export time.
The math macros system is quite complex. Macros are updated during
metrics calculation, so a missing update is very likely to cause a
crash. This commit tries to assure that they are updated at export
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.

83d8e12cc1 Rename Cursor::setSelection(bool) to selection(bool)
The old name would be confusing wrt setSelection(), which does additional checks.
This one is a pure acessor, and the more complete methods are
* setSelection(), which avoids empty selections
* clearSelection(), which resets anchor, and sets word selection and mark more to false.

Most of the code should use these two instead of selection(bool), but this is for later.

5aa342ed75 Fix cursor position after redo
When document settings are modified, a command
  inset-forall Branch inset-toggle asign
is run to open as needed all branches. At the end of the said loop,
the cursor is reset to where it was. However, the cur_after undo
element member is not set because it already had a value.

To make this work as expected, it is necessary in LFUN_INSET_FORALL to
reset the cursor before ending the undo group and to insert a dummy
recordUndo call.
