since a few months MiKTeX's package manager required the option "--admin" when calling it with admin privileges
- also register the .lyx22 file extension to be opened with the future LyX 2.2.4
Instantiating a single QSettings and using it for each ui element
can significantly shorten the time required to save the various
states at exit. The speed up can be better appreciated on *nix,
where the settings are saved on disk, rather than on Windows where
they are held in memory (in the registry).
Add sips as a fallback converter for Mac to provide preview of PDF graphics in LyX when pdftops is not installed.

We need to invalidate the BibTeX cache when undoing or redoing. I do
not like having to do it for every undo or redo. We should only have
to do it if we restored or deleted an InsetBibTeX. But there is no
way, so far as I can see, to do it that way. I tried.

Since TeXLive 2016, "fontspec" maps the ligature break command
\textcompwordmark to the ZWNJ character (U+200C).
This character is missing in many fonts (including the default: Latin
Modern) which leads to "Missing character" warnings in the XeTeX/LuaTeX
log file if a document using non-TeX fonts contains a ligature break.
LyX reports missing characters as error since fixing #9610.
In case of "invisible" characters, there is no data loss, in case of the
ZWNJ the functionality is kept: ligatures are prevented also if the ZWNJ
is missing in a font.
Therefore, a missing ZWNJ is now treated similar to missing characters
in "nullfont" (see [63f41711/lyxgit], bug #10394) and does not trigger
an error.

The previous redirection of the senseless option "bb" to "viewport" in
PDFLaTeX output has been removed in a recent graphics package update.
This breaks documents, since clipped graphics silently stop displaying.
This change restores the previous output by using "viewport" instaed of
"bb" for non-PS/DVI output, while leaving PS/DVI untouched (where "bb"
and "viewport" behave differently.
Fixes: #7910
The variable CPACK_DEBIAN_PACKAGE_RELEASE has to be in the form
of "^[A-Za-z0-9.+~]+$". We will use the abbreviated commit revision for now.
Without this change cmake 3.10 emits error.

In some cases, it is possible that the BufferPositionMap has
dangling pointers. We thus check whether the Buffer is loaded
before accessing it.
Fixes: #10766
(cherry picked from commit 4f50cbcfe4)
The code in InsetLabel::updateReferences code changes reference insets
in potentially several buffers. When recording undo, it is important
to use the right undo stack, otherwise crashes can ensue.
Once it is done, it is neccessary to create undo groups as needed.
This is done using UndoGroupHelper. This demonstrates a shortcoming of
UndoGroupHelper: if a buffer is encountered in two seperate
occasions, two undo groups will be created for this buffer. This is
not correct.
Fixes bug #10643.

It was not a good idea to rely on QTextLine::naturalTextWidth() to
compute a string width. The correct method is horizontalAdvance().
Also round the value to the nearest pixel, since this is what
QFontMetrics::width() does.
By contrast with the code in 2.3.x/master, this code had to be adapted
for Qt < 4.7, where horizontalAdvance() is not defined and
naturalTextWidth() has to be used instead. The fix is thus only
effective starting from Qt 4.7.
Fixes bug #10700 (and maybe others).

The renaming happened in 2013. Contrary to what is stated in the
babel-vietnamese manual, option "vietnam" does not work anymore.
Also, the special care is not needed anymore, since language options
are not hardcoded anymore in babel.
Fixes: #10743
We do not want the cleanup work to be interrupted by a buffer exception.
Spotted by coverity. See bug #9979 for discussion.

This is a consequence of 060a9664, although it is not clear why. The
contextMenuEvent code of the workarea should not delegate context
menu when it cannot honor it.
Also fix a small memory leak.
Fixes bug #10616.

This fixes an error in the preview generation with polyglossia
and bidi that prevents snippet generation (and consequently also
"math as image" xhtml output).
Fixes: #10716.
In some (not yet understood) situations, the paragraph metrics cache
is empty in generateSyntheticMouseEvent(). We just avoid a crash in
this case, but there is probably an underlying problem that deserves
being fixed.
Fixes bug #10324.

While 1c07c0dc was too strong and broke mathed, 4499680b is too
lenient and can accept insets (mathed/CommandInset, InsetInfo) that
have a positive nargs() but are not editable (because they encapsulate
something).
Therefore the best solution for now is to use editable() in text and
isActive() in mathed, until those two things are merged.
Part of #10667.
(cherry picked from commit 13c3c1485b)
This is a relic from IU (Inset Unification): editable() is for text
insets and isActive() for mathed. This needs to be cleaned up.
Part of bug #10667.
