We fill up edited insets into cache when editing inset is triggered, but
this cache is never cleared up for dialogs unassociated with some inset
- thus when e.g. graphics dialog is open for completely new image the
old cache is (wrongly) used.

With Qt 5.11 at least, RtL text will be drawn RtL even when the
(undocumented) flag Qt::TextForceLeftToRight is applied to the
QTextLayout object. This creates selection issues for Hebrew text
marked as English.
The solution is to do the same as in breakAt_helper, that is prepend
the string with a direction override unicode character.
Doing this requires to introduce a TEXTLAYOUT_OFFSET constant that has
to be used wisely to account for this extra character.
Fixes bug #11284.
We used to need a hack to set the size of the layout combo, but
the code was changed in Qt 4.5 or so. Hence the appearance of this
bug in 2009. We can now just remove this hack, and all seems to
work correctly.
The filters for the layout combo and document class combo share a
problem: If you type "beam", e.g, in the latter case, then we will
show any document class that contains those letters, in that order,
but not necessarily consecutively. This is extremely confusing and,
as José put it, just weird. So let's fix it.
I'd call this a bug so would be happy to see this in stable, too.
This code has issues and there is no evidence that it improves performance.
Remove LyXRC variable \use_pixmap_cache and update rc format to 29.
Now the global pixmap cache is only used by GuiCompleter. Therefore
there is no need to reset it when fonts change.
If we were not ready to paint the screen, this does not mean that we
should give up on repainting, just potpone it.
I thought that it was bad to call update() in the paint event, but I
cannot find reference to this anymore and everything seems to work as
intended.
We do not know what to do with horizontal scrolling events, so we ignore them.
Note that the code has to be different between Qt4 and Qt5.
Fixes bug #11257.
This returns a localized version of a string (in the GUI language)
if available, removing trailing colons and accelerator marks.
This can be used to refer to dialog items in the docs in a portable way.
When searching for and item in the menu, also try to consider those that
require a BufferView (such as View/Update formats).
Also, be explicit for the default format in order to find it.
Fixes: #9851
