When the cursor in RTL text, icons for "depth-increment" or
"layout-toggle Enumerate" look wrong.
To fix this, the lfun "bidi" is introduced. "bidi ltr func" behaves
like "func" in LTR text, but is unknown in RTL text. "bidi rtl" does
the opposite. This allows to add two icons, but only have one icon
available. When no document is available, only LTR is assumed.
To make this work, the handling of unknown functions in toolbar has
been changed so this these functions can change dynamically their
existence.
The icon themes `default', `oxygen' and `classic' have been updated
accordingly.
Fixes bug #4451.
The last 20 applications are saved now and accessible both via the lfun
(textstyle-apply n) and the toolbar (via button menu)
Fixes: #7133
This also changes the default icon and toolbar position of the action,
as requested in #11427
Now that we have module support for literate programming, it is possible to do a noweb cleanup. This is basically a patch from Kayvan Sylvan:
- get rid of literate-xxx classes
- rename Scrap to Chunk, since this is the name noweb doc uses (Scrap is from nuweb)
- update lyx file format and add lyx2lyx support for gettting rid of literate-xxx classes
- update documentation
On the top of it, update tex2lyx to
- avoid creating files with literate-xxx class
- fix conflict between parsing << as a quote and parsing it as a Chunk
- create Chunk layouts instead of Scrap ones.
