More complicated than I wished for, but color handling in RTL is
particularly tricky.
The three versions are needed due to the differences between [pdf]latex,
xetex, luatex/luabidi and luatex/babel.
Graphics "height" is only the height above the baseline and thus not
what most people will expect. Also, using height can result in a
division by zero with rotation.
Use totalheight now since this means "height of the figure" (independent
of the baseline).
The custom options field can be used if height is really desired.
We handle this in conversion/reversion, respectively, so document
output will not change.
Hence, file format change.
Fixes: #9676
In particular, the directory frontends/qt4 is renamed to frontends/qt.
Many configurations file have to be updated. All mentions of qt4 in
the source have been audited, and changed to qt if necessary.
The only part that has not been updated is the CMake build system.
This effectively allow paragraph breaks in insets only for cosmetic
reasons (e.g., to align contents on different lines).
This is the last change necessary for an enhanced covington gloss support
(which uses the new covington gloss ui)
A branch inset modifies the layout of the internal structures in
which the text is organized. When a branch is active, it is as if it
was not there, but its only presence makes a paragraph which would not
be the last one to actually be the last one, or the check for the
language of the previous paragraph to fail because there is no
previous paragraph before the first one in a branch inset.
Oney way I found to tackle it, is tracking whether the typesetted
paragraphs are actually part of an active branch inset and acting
accordingly.
Instead of writing a metrics() method that mimics what draw() does,
re-use the draw code with a null painter.
This has the additional benefit of fixing InsetSpecialChar logo width
with EB Garamond. I have to admit that I do not know why it was too
large with the old code, but the new code is shorter/better anyway.
This code removes logowidth(). metrics() is moved to a different
place, but only the logo cases are touched.
It might be nice to do this also for other insets that allow editing.
To do that properly, we'd want to standardize how such insets call an
external (or internal) program, which I guess would mean a virtual
method corresponding to editIncluded. When it exists (i.e., isn't null),
then we could call it, and we'd only need one centralized method to do
that. But at the moment, we have editGraphics, etc.
The basic problem here is that rather than using an abstract syntax,
backend-specific param strings are produced in the listings dialog,
depending on whether listings or minted is used.
Of course this breaks if a user switches backends inbetween (s/he would
have to open and re-apply each and every listings inset!)
Do at least the most basic translations in InsetListings::latex().
A sane solution would imply the use of only one param syntax with
respective interpretation for each backend. But this would be a file
format change.
