bidi.lua:
- Revert "Alias everything to Bidi.nowrap() when in LTR UI,
as using LTR isolates seems uneeded when already LTR" (part
of a628714f) which was a wrong assumption: we need proper
wrappers for all things paths. Enhance some of these wrappers.
- Fix GetText RTL wrapping which was losing empty lines and
trailing \n.
- Wrap all paths, directories, filenames in the code with
these wrappers.
- Wrap all book metadata (title, authors...) with BD.auto(),
as it helps fixing some edge cases (like open/close quotation
marks which are not considered as bracket types by FriBiDi).
(Needed some minor logic changes in CoverBrowser.)
- Tweak hyphenation menu text
- Update forgotten SortWidget for UI mirroring
- KoptConfig: update "justification" index for RTL re-ordering,
following the recent addition of the page_gap_height option.
Allow TextBoxWidget new text direction/lang parameters to be
set on upper widgets, and propagate them all the way to it
(ScrollTextWidget, InputText, InputDialog, TextViewer).
Use specific non-default ones in some specific cases:
- Force LTR text direction when showing HTML and CSS, and
configuration files (in some plugins).
- Use Wikipedia server language and text direction when
showing an article.
- Use auto with Dictionary results, as we don't know the
dictionary language, and they may contain mixed content.
- Force LTR when showing some paths (still needs more of them)
TextEditor plugin: add 2 new options "Auto paragraph direction"
and "Force paragraph direction LTR".
Footnotes popup: grab HTML direction, and forward it
to MuPDF for proper display.
