In case of path names for external files containing symbolic links the real path
and the logical path name may be different for the same file or directory.
LyX is using QDir::tempPath() to create the path name of the temporary directory.
The Qt implementation is free to return the logical or the real path name here and
it happens to be different for various platforms and versions.
The most stable and clean solution is to use the real path name consistently.

LyX relies on a a backing store to draw when running under macOS or
Wayland, because Qt arbitrarily overwrites parts of the workarea
before we paint (and we paint only the parts that need to be painted).
However it seems that this is also necessary on X11 when the WM theme
is translucid. Since there is no way that I know of to detect this
situation, this patch adds a LyXRC setting to manually select this
drawing strategy.
Note that using a backing store is not always a good solution, since
this disables subpixel aliasing.
At this point there is no UI for the variable.

Rather than that, keep it with a warning that it is not available.
Fallback procedure (which maintains security measures) is done in
the conversion step.
This prevents document properties being silently changed on sharing.

When switching class, it does not make sense to flag flex insets that
are undefined if they were already undefined before.
Part of bug #12163.
(cherry picked from commit 009efa195bf2837a007c0b070261b34a715b9b39)
Add code stolen from QBitTorrent and Qt Creator that properly enables
HighDpi handling.
The rules are:
1/ nothing needs to be done for macOS and Qt >= 6
2/ HighDpi support is set by default starting with Qt 5.6.
3/ Support for fractional scaling is added for Qt >= 5.14.
Hopefully fixes bug #12060.

The math color inset inherits the mode of the containing inset.
This mode is inferred by the kind of font in effect. Setting the
right mode allows to insert spaces where these should be allowed.
Another small glitch was that the selection was always parsed in
math mode, so that any space was swallowed, even if the inset would
allow them.
We lack the necessary font (cmb10) for drawing bold uppercase greek
letters. It would be overkill adding it for this sole purpose, so
adopt the same poor man's bold strategy used with \boldsymbol.
A reference can be directly inserted into mathed but cannot be pasted
because the pasted material is returned in plain text format. This patch
allows getting a string from the cut stack in a suitable format allowing
the math parser to actually create an InsetRef.

(cherry picked from commit 22ee249c3ea6426dbf24956ae36986e3ee6f81c0)
When hitting backspace in the first position of a cell in mathed,
if the cell is part of an array, the whole array is dissolved
and the sole cell content pasted in the containing environment.
But if the cell is part of an eqnarray or align math hull type, the
cursor is simply (and unexpectedly) taken out of the whole equation,
which is left unchanged.
This patch makes backspace equivalent to the cursor left key in those
cases, while leaving the behavior unchanged in all other ones.

It turns out that the code is the same in texted ans mathed and that
whatever is done in InsetTabular is not useful.
This means that we do not need to deal Text::dispatch idiosyncrasies
(in particular forcing the cursor to be visible).

The method horizontalAdvance() replaces width() starting with Qt 5.11.
To handle this, all direct calls to QFontMetrics::width() are replaced
by calls to GuiFontMetrics::width(), and the code for
GuiFontMetrics::width(QChar) uses horizontalAdvance on newer Qt
versions.

Private message by Michal Hoftich (tex4ht head developer):
oolatex is not recommended way to use Tex4ht for the ODT conversion.
It is better to use
make4ht -f odt mwe.tex
make4ht fixes some issues in ODT files
This is candidate for stable.

To do this, hard-coded test for xcb had to be replaced with a call to
platformName(). Since this method does not exist in Qt4, we emulate
it.
Note that Qt5 uses xcb bindings for X11 system, while Qt4 relies on
older X11 bindings. We return platorm == "qt4x11" in this case.

This amends ea81faa9 that only took into account the postscript format
and did not consider that without GUI an image is not available even if
if it is actually cached. In this case we load the image for obtaining
its dimensions in order to correct the clipping bounding box.
