Do not take the optional arguments from the first paragraph, but from the
paragraphs whose layout have no arguments, consistently with the code in
InsetArgument::updateBuffer (i.e. what was shown on screen).
With these changes, equation numbers are shown properly on screen.
When setting is default, we guess the side using these two rules
* ams(art|book) and siamltex classes are leqno by default. This is
signalled because the classes provide "leqno" (in amsdefs.inc). If
there are other classes that do this in output, the relevant classes
should be updated.
* the language arabic_arabi also sets leqno by default. This is
currently hardcoded for lack of a better idea.
Besides, a few bugs are fixed:
* use mathrm instead of mathbf for numbers metrics
* set spacing between maths and labels in inches
This commit replaces the string math_number_before by a proper math_number enum.
Note that the _before naming was misleading. It was chosen at a time
when we were not sure whether leqno was always left or could be right
in RtL documents.
Note that the token in LyX document is still \math_number_before and
this should be changed.
Fixup for 19cc4a1f.
as discussed our support for the formula numbering side should be complete. There are document classes that uses left numbering as default and with the class option "reqno" this can be changed to right numbering. reqno requires the loading of amsamth.
Consider mathbin, mathrel and mathpunct as word separators. This makes
Ctrl+{Left,Right} more intuitive, quicker, and more different from {Left,Right}.
This takes into account all the feedback from the discussion on the general
list. Further feedback welcome.
Setting the default working directory to '.' is an invasive change
on Mac and Windows, where the current working directory of LyX when
LyX is started from the GUI is not a reasonable choice for the
default directory in e.g. the "save as" file dialog or the "open"
dialog. A similar situation could happen on Linux distributions (I'm
not aware of any, e.g., POSIX standard that defines that the working
directory of a binary started from GUI should be the home
directory). Thus, it is not clear this default is good on any
platform.
If the user wishes to have the behavior of '.', the description in
the "paths" preferences pane provides the information for making the
change.

This reverts commit 892593fbdc.
- Adds a currentZoom variable which holds the current zoom level.
- The zoom stored in preferences is used as default zoom level (default binding:
M+0).
- The currentZoom is saved and restored via QSettings.
- Adds LFUN buffer-zoom for (re)setting zoom.
This is done by two things:
1/ the equation returns LefAlign as display() value
2/ Inset::indent() return a value (in general 0) that should be added
on the left (or right in rtl) of the inset when it is flushed.
The code that uses these values is in TextMetrics::computeRowMetrics.
The current set of options to provide include names of
the find and replace internal buffers, something out of
reach for the user. Furthermore, options are provided
using a multi-line syntax, which cannot be entered
using the mini-buffer AFAIK.
Length::inPixels(MetricsBase const &) and VSpace::inPixels(BufferView
const &) should be moved respectuvely to MetricsBase and BufferView:
core file are not supposed to use GUI files.
This reverts commit d4ea07705a.
d4ea0770 lead to a compile error with gcc 4.6. The error is likely
due to that version's weak C++11 support.
This commit reverts d4ea0770 in order to preserve compilation with
gcc 4.6 for alpha1.
New special character to mark an optional line break
without inserting a hyphen (ZWSP). See #10585.
Corresponds to the Unicode character U+200B ZERO WIDTH SPACE
This isn't a “space”. It is an invisible character that can be used
to provide line break opportunities.
http://unicode.org/notes/tn27/
While the literal Unicode character can be used in the LyX
file, it is invisible in the GUI.
For visible feedback, the patch adds a new special character "allowbreak".
The small mark is inspired by LibereOffice.
A tooltip is added.
Use Length instead of HSpace for math_indentation and rename it to mathindent.
Get rid of the string version.
Rename (g|s)etMathIndentation() to (g|s)etMathIndent().
Remove the HSpace class altogether.
Some cleanups to parindent support to look like mathindent.
- remove quotes around length
- use "default" for default parindent, instead of an empty string
- Fix the constructor Length(string const &) so that an empty string
corresponds to an empty length (coherent with Length::asString()).
This reverts commit d568846e03.
Unfortunately the used alternative API LSCopyDefaultApplicationURLForContentType
is available with 10.10 and later only and cannot be used therefore. So there
is no alternative to deprecated calls ATM. LyX 2.3 should run on 10.7 at least.
When applying or saving Document Settings, LyX no longer opens or
closes branch insets. The intent of the previous code was to open
branch insets of a branch that is activated, and close branch insets
of a branch that is deactivated.
After some discussion [1], it was decided that the behavior intended
by the previous code was inconsistent with activating/deactivating a
branch in the context-menu of a branch inset, and the previous code
assumed a workflow of the user, rather than letting the user
separate opening/closing branch insets from activating/deactivating
them.
This commit modifies fd6cd728.

1.) The command check_layout exits with "0", even if the module contains errors.
The new module check_layout.cmake tries to compensate.
2.) Added default style to the test layouts when checking single modules.
Seemingly, when removing an argument from argv, and thus inserting
a null pointer to shorten the array, causes an assertion because
the null pointer is not a valid heap pointer (sic!)
Fixes bug #10440
When trying to do implement a LaTeX feature on screen, it is always
good to see how LaTeX does it, just in case it is easy to implement on
our side.
Then we have a correct output at all DPI sizes.
- LyX has new preamble tags. Although that they are not relevant for LaTeX they must be created by tex2lyx nevertheless
- also fix an issue that the formula indentation was always output
- update the tex2lyx tests accordingly
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.
This is a simplification of commit eb4a2a19, which has been reverted
at 01f0ab64a.
Fixes part of bug #10569.
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.
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
This allows to fix distclean properly, since we know that
subdir-objects is used. When it is the case, it is not a good idea for
a Makefile to use a source file which is under the control of another
one. This could not be made to work work with old automake versions
(<1.14).
Therefore we refer directly to object files in Makefile.am instead of
source files. The actually leads to less compilation in tex2lyx.
Update the code here and there to remove compatibility hacks. Update
documentation.
Re-enable the layout test and fix the Length test, which was ovewriting
memory in test_inPixels() because lyxrc did not had a correct layout.
As it was, the comparison buffer was sharing a DocumentClass with
one of the compared buffers. I don't fully understand why this was
causing a problem, since we use a shared_ptr. But this patch creates
a new DocumentClass for the new buffer.
This is preliminary work to make roots look more like in TeX output:
* correct font size for root order
* set minimum size of the root from the max ascent descent of the
font. This is what TeX does.
* fix drawing, and in particular horizontal size.
More needs to be done, in particular:
* handle zooming and dpi correctly by removing hardcoded pixel values.
* factor the code for the two types of roots in one.
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#10569.
Coverity flags this code as not handling exception that may happen in buffer().
My own analysis is that this can never happen because isBufferValid()
does check whether buffer_ is null.
Any insght appreciated. The commit should be expeanded to more cases, actually.
The RenderButton object now has this property. It is set depending on
the value of inheritFont() method that is currently only set for
InsetRef, InsetBibtex and InsetCitation.
Fixes bug #10258
There a some exceptions related to the fact that BOOST_ASSERT throws
an unhandled exception, which is fait enough. This is handled by
uploading a modeling file to coverity.
The second batch of issues are related to the use of lexical_cast in
convert.cpp. We use now a wrapper around boost::lexical_cast that does
not throw but return empty strings instead. I am not sure actually of
when lexical_cast could fail.
The special mode used by macros where the macro name is displayed as
grey text in a box is now one of the possible marker types for any
inset. The new code puts the macro name below the text, which means
that only the text below the current line will be moved. This makes
edition much more comfortable. The grey border around the contents has
been removed too.
The marker_type enum has been moved from Inset to InsetMath. A
markerMargin() function returns the horizontal margin required on each
side for the marker. Only the corner-type markers MARKER and MARKER2
need some.
A new BOX_MARKER enum value has been added and is taken care of in
afterMetricsMarkers (renamed from metricsMarkerVertical) and
drawMarkers.
The InsetMath::marker() macro now takes a BufferView pointer as
argument, so that the marker type can depend on editing state.
MathRow::metrics now makes changes to the MathRow object when needed.
The specific metrics/draw code in MathMacro has been removed and
replaced by assertions. Code in addToMathRow and marker is adapted to
reflect the cases where linearization is possible.
Rephrase positively the check box for the output of en- and em-dashes
and disable it when using non-TeX fonts. The state of the check box
is remembered, so that toggling the non-TeX fonts check box does not
cause information loss.
This commit fixes the regression introduced in 2.2 about the
output of en- and em-dashes. In 2.2 en- and em-dashes are output as
the \textendash and \textemdash macros when using TeX fonts, causing
changed output in old documents and also bugs (for example, #10490).
Now documents produced with older versions work again as intended,
while documents produced with 2.2 can be made to produce the exact
same output by simply checking "Don't use ligatures for en-and
em-dashes" in Document->Settings->Fonts.
When exporting documents using TeX fonts to earlier versions, in order
to avoid changed output, a zero-width space character is inserted after
each en/em-dash if dash ligatures are allowed. These characters are
removed when reloading documents with 2.3, so that they don't accumulate.
Handle name prefix (aka "von" part) as a separate entity, just like
BibTeX and Biblatex do. This allows to omit or reposition it in
accordance to the current style ("Goethe, Johann Wolfgang" or
"von Goethe, Johann Wolfgang" or "Goethe, Johann Wolfgang von" are all
valid and used).
LyX's name parser should now be on par with BibTeX's.
This patch removes explicit calls to stat() in the DepTable code. The
original motivation was to get read of a stat() invokation where the
error condition was not checked (spotted by coverity).
It is not clear that the optimization is a gain, but it is clear that
it has a cost: some elements of formulas will not be present in the
position cache.
Fixes bug #10520.
Using this global variable in the class is clearly a bug. If we wanted
to avoid doing it by mistake, the variable should be moved to the LyX
singleton.
Also add an underscore to the private variable formatlist_.
When we have a name with more than two parts, but no "von",
it was coming out as, e.g.:
Obama, Barack Hussain Obama
i.e., with the last name appearing twice.
Also adds a check for names without spaces, which would have given:
Pele, Pele
This was not the original issue at #10582, so that bug is still
open (though I cannot reproduce it).
The error is reported in the GUI, but for the terminal we must write
explicitly to STDERR.
For a specific example of this type of exception, see the previous
commit, 72c3dbd.
If an included file is not found, it seems impossible that the final
output would be correct. Before this commit, when exporting on the
command line, LyX would create the PDF and exit with a zero error
code so unless the user was monitoring the terminal output, they
would not know there is a problem.
This change is consistent with 1a374a93.
Introduce a distinction between being read-only and having the read-only flag. A
buffer is read-only if either it has been externally modified or if it has the
read-only flag.
Coverity complains that we might read strings that are arbitrary
large, and that this can be a security issue. This is a problem in
particular, when we feed these strings to from_utf8(), which coverity
flags as dangerous for some reason.
The best solution would be IMO to model from_utf8() properly, but I do
not know how to do that. Here I try a different solution, where I
cannot read a string larger than 64k from the file.
Let's see whether this removes part of coverity warnings.
Coverity does not find it obvious that p is never negative. Normally
it is the case (because the items have been filtered), but it is
better to play safe.
The added cmake-parameter is:
-DLYX_EXTERNAL_MYTHES=<value>
where <value> is one of
AUTO (Default) Search first on system for mythes (lib and include)
ON Use installed only (errors if not installed)
OFF Compile the provided source in 3rdparty
Instead of using a coverity annotation (that does not work) it is
better to really iinitialize the members of the object, just in case
somebody decides to actually use the DisplayPath() constructor.
Coverity correctly spotted that the existing code creates a temporary
map and returns a value from it. It is not possible to make the map
const& directly because operator[] may change the map.
Therefore, we use map::find instead.
When including files, LyX always searches the user and the system
directory, in that order. This means that when using local layout
files broken down into multiple includes, the various includes should
be specified with a path relative to the user layouts directory
(typically ~/.lyx/layouts), making this very impractical.
This commit allows including local files by specifying their path
as explicitly relative to the main layout file position, i.e., by
specifying their path with either "./" or "../". If the main layout
is not loaded from a local file, the usual search order is used,
even if the path are explicitly relative. So, for system layouts,
both "Input ./name.inc" and "Input name.inc" are equivalent.
It extended QToolBox with size calculation to fix UI issues with the previous
design of GuiCitation. Since it always needed some kind of hack and since
QToolBoxes do not appear so popular, it probably won't be used anymore.
Because latex allows to do so, and there is no easy way to achieve this.
This was apparently implemented to allow cycling between the various dash
types, but it was a bad idea bringing no benefit and causing griefs.
Previous fontspec loaded xunicode internally, for recent version, this
is no longer desired. However, we still need it for tipa emulation.
We use fontspec's trick to bypass XeTeX test with LuaTeX.
Now the selection is not done by the inset, but by the MathData
itself. This allows for some code simplification and avoids an
extra redraw.
Additionally, this fixes the selection inside macros, which was broken
by the new MathRow code.
Useful to cache copies of objects, including shared_ptrs. No risks of dangling
pointer, and avoid naked pointers in the source.
Fix memory leak when compiling with Qt5.
Now backspace and delete in text will select non-empty math and text insets
before deleting them. This is consistent with what happens in math already.
This is implemented for InsetText as well but can be disabled in case of
negative feedback.
This can be set for any sort of inset with the new virtual method
Inset::confirmDeletion.
New option "force" for the LFUN_*_DELETE_* commands, that bypasses the
confirmDeletion check.
The special mode used by macros where the macro name is displayed as
grey text in a box is now one of the possible marker types for any
inset. The new code puts the macro name below the text, which means
that only the text below the current line will be moved. This makes
edition much more comfortable.
The marker_type enum has been moved from Inset to InsetMath.
A new BOX_MARKER enum value has been added and is taken care of in
afterMetricsMarkers (renamed from metricsMarkerVertical) and
drawMarkers.
The InsetMath::marker() macro now takes a BufferView pointer as
argument, so that the marker type can depend on editing state.
MathRow::metrics now makes changes to the MathRow object when needed.
The specific metrics/draw code in MathMacro has been removed and
replaced by assertions. Code in addToMathRow and marker is adapted to
reflect the cases where linearization is possible.
From now on \kern and \mkern remain as ERT as long as the length is invalid.
Fixes#10539 (regression at 10c8d51b).
The only way to produce an InsetMathKern now is via parsing (i.e. file opening
or copy-paste). This is because there has never been any sensible way to input a
valid InsetMathKern, but this is another issue.
Since in InsetMathNest::cursorPos we do not know what is the value of
the row element before value of a given BOX, it does not make sense to
set the cursor at a given offset from the start of the MathData
object.
Therefore here we set the cursor in the middle of the MathData object,
which unfortunately may or may not be visually centered wrt the BOX.
The best solution would be to use the MathRow data here, but
unfortunately this is not completely trivial.
This patch replaces 7917ebcc4.
Horizontal space is now added for linearized macros too.
Vertical space handling is done in a separate method.
This is in preparation for handling of 'box' macro editing mode in
MathRow.
The current version was wrong for non-English dialogs, and even for
the English one, due to the translator commands that were not removed
for calculation (as in "Formats[[output]]").
Candidate for stable.
This adds support for the chapterbib package, but also adds ways to
produce this sort of multibib with biblatex and bibtopic (which are
both incompatible with chapterbib).
File format change.
InsetMathDelim does not need markers because the delimiters are
visually enough.
CommandInset (like InsetMathRef) does have cells, but they are hidden
(only for storage). Therefore the default InsetMath::markers() method
mistakenly added markers. In practice, the markers were never active
(since the cursor cannot go into the inset), but some space was
reserved for them.
This allows to somewhat simplify the text and avoid some uses of
Paragraph (in the long term, RowPainter should not have to access
these things).
At the same time do a small cleanup to RowPainter: rename
text_metrics_ to tm_, remove pm_ and width_.
The enum values BEG_MACRO/END_MACRO and BEG_AR/END_AR are replaced by a
single BEGIN/END pair.
The MathRow code now only knows about insets and math arrays.
New hooks (before|after)(Metrics|Draw) are run by the MathRow code
as needed. They are actually also used internally by the MathMacro
code.
The gain is that most traces of explicit macro handling (and
the MathRow::Element::macro member) have been removed from MathRw.cpp.
The next step will be to extend the tokenizing process to allow for
linearizing insets other than macros.
* Convert the kerning into a proper right margin for mathnormal, mathscr and
mathcal (fonts with \fontdimen2 == 0 as per rule 17 from TeXBook).
* Simulate the fact that characters in mathnormal fonts have a 0-width left
bearing.
* Implement subscript positioning in the case of rule 17 using negative italic
correction (kerning_).
File format change.
This allows for the relevant InsetCommand-based dialogs (such as
citation text before/after, Bibitem label, hyperlink name etc.)
to provide both the input of verbatim code or text that is transformed
to proper LaTeX code.
Some dialogs (Nomencl, Href) already had some methods (although they
could not be toggled), which are now centralized and streamlined.
The initial work of this patch has been done by Georg Baum (see
http://www.lyx.org/trac/attachment/ticket/2751/x.diff)
Fixes: #2751, #8227.
When using Qt stuff in breakAt, it may happen that the row is broken
after an hyphen (whereas the old code would only consider spaces).
The fact that we abuse the Row::right_boundary() property to detect when
a row should be flushed broke justification when a row is cut at an
hyphen.
Fix this by introducing a new Row::flushed() property and set it as needed.
The code that tries to decide whether it is worth splitting a given
text row element had a shortcoming: it did not take into account the
left margin of the new row that would be created.
The problem is that this left margin is not the same as the left
margin of the current row, because there can be for example
indentation effects.
To fix this problem, we pass the amount of available space on the
next row as a parameter of Row::shortenIfNeeded.
Note that there is no need to care about RtL row elements at this
point, since the bidi algorithm will be applied to the row
subsequently.
This avoids some duplicate code. Note that the return value of
Paragraph::getAlign had to be changed. I suspect it was set to char to
avoid reading one header file in Paragraph.h.
Whenever an argument delimiter is used inside the argument, the argument
needs to be grouped, that is
\cites({text (text) text})
or
\cite[{text [text] text}]
This fixes the original case reported in #2751 which is independent
from the general issue that the pre- and postnote field take literal
code.
Starting with Qt 5.6, setting the environment variable QT_SCALE_FACTOR
makes everything accordingly bigger. So, if QT_SCALE_FACTOR=1.2, all
text and GUI elements are rendered 20% bigger. However, if an application
does not account for this, everything will also look "blocky".
With this commit, all text and images will be scaled remaining sharp.
This works whether a HiDpi screen is used or not, but is mostly useful
with a HiDpi screen, as all GUI elements are more spaced apart and one
can use the mouse for selecting things without requiring a high precision.
These are biblatex-specific multicite commands that allow for multiple
pre- and postnotes, as in:
\cites(pre)(post)[pre1][post1]{key1}[pre2][post2]{key2}...
with an optional general pre- and postnote, which applies to the whole
list (like [][] in normal cite commands) and an optional pre- and
postnotes for each item, so that pagination can actually be specified in
multi-cite references, as in:
(cf. Miller 2015, 2; furthermore Smith 2013, 23-23; Jenkins 2012, 103,
also refer to chapter 6 in this book)
See the biblatex manual, sec. 3.8.3., for details.
File format change.
It seems that QTextLayout does not handle properly a single character
with 0 width. This breaks drawing of things like \not.
Actually the problem had been worked around already in lib/symbol. The
work around can therefore by removed now.
[additionally, remove extra spacing from \mapsto, \Mapsto]
Add a pixel gap around boxes.
When a box is invisible, its width should be null (but keep the weight
to avoid drawing problems (think empty sqrt in a macro).
Fixes missing outliner names in various situations. Now if the warning "Missing
outliner name" appears in the console, this correctly hints at an actual issue
with the layout.
Biblatex can be used with Japanese, but then, biber (not pbibtex) should
be used as processor.
I this context, bring the jbibtex UI in line with bibtex, allowing for
a selection of alternatives.
This is now set as default. It selects biber for Biblatex (with
fall-back to first bibtex8, then bibtex, if the former is not
installed), and bibtex for BibTeX-based engines.
With this, users do not normally need to care for the processor when
they switch cite engines.
The goal of this patch is to be able to properly remove the space
needed for markers in the case of insets that are inside macros and do
not need these markers. This was attempted at 9a9a6a8, but did not
work reliably.
To this end, the following simplifications are made:
* instead of drawing its own markers, each inset has a virtual method
marker() which prescribes either NO_MARKER, MARKER (normal bottom
marker) or MARKER2 (top and bottom marker). All explicit calls to
(draw|metrics)Markers(|2) are removed.
* the space necessary for the markers is now counted in the
before/above margins in the row structure. Therefore painting will
not happen at (x + 1, y), but just (x,y).
* the methods drawDecoration are removed.
* the helper methods InsetMath::(draw|metrics)Markers(|2) are removed
and replaced by a new function drawMarkers in MathRow.cpp.
Now the marker type is kept in the MathRow::Element object (and set to
NO_MARKER in not editable context) and the marker is accounted for in
MathRow::(metrics|draw).
Moreover, the extra pixel for the marker is taken on the before/After
space if possible. The marker will only require extra space when
before/after is 0.
See comment 168 of #8883 to understand what issues are fixed.
The rewrite of macro_nesting done at 0f15dcc6 was faulty, in
particular since the information should be available also at draw
time. To this end, we revert the patch of the said commit that removes
macro nesting information from MathRow::Element. In the next commit,
we will change the marker code so that MathRow::draw does not need the
nesting information.
Actually the code is now cleaner since the macro nesting stack of
MathRow::metrics can be removed.
When cloning InsetExternal, the tempname_ member of InsetExternalParams
has yet to be initialized. So, trying to remove it causes the warning
"QFile::remove: Empty or null file name".
No one seems to have been adding them `thematically', and it's too
hard to know how to do that, anyway. This at least makes it easier
to scan through the list.
I have verified, by re-generating LFUNs.lyx, that no significant
changes have been made here.
inset.
If the reference is "sec:mysec", then this will output just "mysec".
This is what is needed, e.g., to use refstyle's range commands, e.g.,
\secrangeref{mysec1}{mysec2}
You *cannot* use:
\secrangeref{sec:mysec1}{sec:mysec2}
even if those are the actual labels.
Eventually, I'd like to add native support for this, but I'm a bit
frightened of trying to make the reference dialog support multiple
selections.
This _must_ be increased for xhtml output of fullcite, else we get
fragmentary html code.
I am aware of the reason for this size limit (#8944) and have carefully
checked that this is not affected.
* ifentrytype:<type> whether we are a specific entry type (e.g. "book")
* export: export context (as opposed to dialog or workarea)
* second: whether we are in the second item of a list (useful when you
need to separate by " and " or ", and "
This entails a change of getAbbrAuthor to getAuthorList (the default is
still abbreviated with respect to MaxCiteItems, but the list can be, at
explicit request, shortened or full notwithstanding MaxCiteItems.
This will be used to transfer any single-cite related information from
anywhere to BiblioInfo (instead of the many strings and bools we use
until now).
This is a prerequisite for some forthcoming fixes and enhancements.
Copy-pasting $#\n$ from text to LyX gives the error message:
MathMacroArgument::MathMacroArgument: wrong Argument id
and it is not hard to get a crash soon after.
There are legitimate uses of # not followed by 1..9 in LaTeX and it is good to
parse them correctly when importing from LaTeX.
Following discussion on the list:
https://www.mail-archive.com/lyx-users@lists.lyx.org/msg103012.html
This defines a new behaviour for Ctrl[+Shift]+Arrow in math:
* Left/Right does not enter insets
* Left/Right jump groups of insets that have the same math class ("words")
* Enable Up/Down for consistency.
This was missing for macros defined in lib/symbols. This only affects the
equation splitting since global macros are always linearized. This fixes#10107.
Testcase: Define a math macro \AA, overriding the definition of \AA from
lib/symbols, then insert it in math mode.
* Before this commit: \text{\AA}, and \lyxmathsym{\AA} after deleting \text, but
displayed like \AA.
* After this commit: \text{\AA} is inserted, but one gets \AA after deleting
\text. The output is now consistent with the display and the meaning.
* Expected: only \AA is inserted. This is unfortuately not what one gets; for
this to work, the scope of the macros would need to be resolved upon creating
the inset.
About removing the changeEnsureMath in MathMacro::{metrics,draw} : as it is only
called in edition mode, it only happened for user macros for which no ensureMath
is needed anyway. ChangeEnsureMath should indeed be applied for global macros,
but since they are linearized there is no obvious place to call it.
