Without this setCurrentFont() is not correctly called on the
BufferView cursor and the cursor could appear in L-form.
Fixes bug #10686.

This issue was already addressed in the all_sel case. It only happens
at specific zoom and jusification values.
Fixes part of #8883.

The test added at 359aef92 was incorrect. Actually, Inset::editXY
returns the inset when it is edited and also when it is not, which
can be confusing. So if we are unlucky and the slices positions in the
text area and in the inner inset match, the code below triggers and
many bad things can happen.
Also improve the documentation of Inset::editXY and TextMetrics::editXY.
Fixes#10691.

Make sure to properly nest \begin{lang} and \end{lang} tags even
when no language package is selected. In this case, LyX assumes
that babel is being used, so the language names might be wrong
if the user arranged for using polyglossia in the preamble.
Nevertheless, we assure that the produced output is syntactically
correct, so that by adding proper preamble code a correct output
is still possible.
As it was, the comparison buffer was sharing a DocumentClass with
the buffer from which the document settings are taken.

It seems that the internal Qt5 caching does not work well here,
especially in the case of ancient Hebrew documents.

When an inset wants to use the whole available width, it is necessary
to take into account that some of this width may already be taken by
the end-of-paragraph (pilcrow) marker.
Fixes bug #10537.

getPosNearX, which is the only user of x2pos, should always return the
nearest position.
In editXY, there is a need to return the position where the inset
stands, but it is done using checkInsetHit.
Fixes part of bug #10569.

The code that looks whether neighbor block has a different direction
should look to the left or to the right depending on the direction of
the current block.
Fixes part of bug #10569
(cherry picked from commit e3d252cd62)
Instead of using complicated (and wrong) code, it is better to use
getPosNearX here.
Also simplify the code by removing temporary variables.
Fixes part of #10569.

With RtL text, the method can be non-monotonic wrt x value (which is a
Qt bug). To work around this, we check whether positions adjacent to
those returned by xToCursor look better. Depending on whether the new
x position is too small or too large, we look backward or forward for
a better solution.
The performance is probably not great, but this is only needed for
user interactions, so the performance penalty should not be a problem.
Fixes part of #10569.

the previous commit changed the LyX logo to be in English but that broke the PDF bookmark text and also the TOC. The solution is to use the real logo and a short title with \texorpdfstring
