With Qt 5, our code did not correctly detect when icons were
available and thus tried to use nonexistent icons.
QIcon::hasThemeIcon(theme_icon) returns true when theme_icon is
empty. We now rely on the behavior that QIcon::isNull() returns true
if the icon is empty.
The same code is used with Qt 4 and Qt 5.
The old text was incorrect and came from the 2.0 release. LyX works fine if
the default python interpreter is python 3, as long as python 2 is available
as well.
Building LyX does also work with python 3, but since I did not check all
special build steps with both cmake and autotools, I kept a note about
possible problems.
This is used when scaling graphics previews. It is also used on a rare occasion
to scale instant previews when the user's configuration mixes low-dpi and
high-dpi monitors (#10114).
The aim of the tutorial is to explain how to use LyX and not special LaTeX issues with \frontmatter, non-TeX fonts etc. Therefore the preamble should kept clean.
With this change, it becomes possible to run the following commands:
inset-forall Separator:latexpar char-delete-forward
inset-forall Separator:parbreak inset-modify separator plain
The first one deletes all latexpar separators. The second one turns parbreak
separators into plain separators. This is safe, flexible, and avoids adding a
new LFUN.
As such, it shall be protected in moving arguments, such as sections.
Fixes bug #10092.

Those two functions used two different hackish and buggy
implementation to know when the function is disabled. Replace that by
asking the containing inset whether it accepts inserting display math
inset.
Fixes bug #10033.

The Reproducible Builds effort (https://wiki.debian.org/ReproducibleBuilds) in Debian (at least) means that 'ar' is built in deterministic mode as default: all timestamps are set to 0.
This is not compatible with the use of the 'u' flag, and therefore ARFLAGS has to be changed from 'cru' to 'cr'.
This gets rid of the harmless but annoying warning
ar: `u' modifier ignored since `D' is the default (see `U')

When in a tabular cell, "this" is just a lone InsetText, while cur.inset() is the whole tabular. This makes a big difference, especially when one wants to count cells.
Fixes bug #9954.

We ensure that configure.py is called by python2, regardless whether 'python'
is python 2 or 3. Therefore we can simply call TeXFiles.py with the currently
running interpreter. This fixes configuration on systems where 'python' is
python 3.
The old name conflicted with the newly introduced Inset::isTable.
Now the meaning is as follows.
* Inset::isTable() is true when the inset is composed of lines and columns
* InsetMathHull::allowsTabularFeatures is true when the current type of hull allows for tabular-like functions.

inset-select-all has 3 levels
1. select current cell
2. select all cells
3. select inset from outside.
The second level makes sense for tables (text and math), but not for things like a math fraction.
Introduce a new method Inset::isTable() that allows to detect this case properly and skip level 2.
