These are now properties of insets that can be operators :
InsetMathSymbols, InsetMathDecoration (for over/underbrace) and
InsetMathMacro (for its contents).
Each of these has a limit_ member that allows to remember a limit
forcing and a member defaultLimits() that indicates what to do in the
absence of such forcing. Moreover the write() method calls
writeLimits().
This allows to simplify the definitions of integrals in lib/symbols by
defining the integrals as macros of their "op" version, as it is done in
the style files.
Also, many hardcoded assumptions can now be removed.
The handling of LFUN_MATH_LIMITS is now done in InsetNest, which tries
successively to apply the limit change to (1) the character after
cursor, (2) the character before cursor and (3) the character at the
end of the inset (useful for script insets?)
The new code allows to define
\newcommand\int{\intop\limits}
but not
\newcommand\makelimits#1{#1\limits}
It is also possible to type explicitly \limits or \nolimits to modify
a symbol.
Includes a test case useful for some of the previous commits (notes in abstract, PI escaping, counter warnings).
Still missing: marginal and side notes. Shouldn't they be ported to InsetMarginal?
The goal is to reproduce the change of size of operators like \sum wen they
are in display style.
The syntax of the symbols file has been extended to allow for two code
points (like 80|88 for \sum). In this case, the second one will be
used in display style.
Update the symbols file to handle all bigops from cmex, esint, wasy and
stmaryrd.
Let the code for math symbol inset handle symbols which can change size,
using the information from the symbols file.
Update the user-facing strings in modercv's layout according to the
documentation of the cventry command in moderncv.
