When a raster image with an advertised pixel density different
from 72 dpi is included in a latex file, the output image dimensions
are scaled by the ratio 72/pixel_density. Hence, if a clipping
bounding box is specified, it has to be scaled by the same ratio,
otherwise the images will be clipped differently on screen and output.
Here we use the extractbb command (present in any TeX distribution)
to ask about the output dimensions of the image as dictated by the
pixel density and compute the scaling ratio by the knowledge of the
actual dimensions. If, for whatever reason, extractbb is not found,
everything goes as before, because the clipping bounding box will
simply not be corrected.
According to this page:
http://doc.qt.io/qt-5/cmake-manual.html
the way to replace use of qt5_use_modules() for module "_mod" and target "_target"
is to use
1.) cmake_minimum_required(VERSION 3.1.0)
2.) find_package(Qt5${_mod} CONFIG REQUIRED)
3.) target_link_libraries(${_target} Qt5::${_mod})
The last one sets all reguired libraries, compile flags and needed includes for the ${_target}
Completion uses a complicated async scheme based on timers to update
itself. This is probably not necessary anymore and is fragile to
event order changes.
This is what happens with the new painting scheme. Therefore the
asyncHideXXX() methods have to be made more robust and detect whether
completion state has changed by the time they are triggered.
When an image has to be loaded a second time and the cache
is not used or the image is not in the cache, its preview is
going to be regenerated again. Hence, if the same image
appears more than once on screen, avoid requesting simultaneous
generation of the same preview.

This exception in the regex constructor is only theoretical (our regex
are hardcoded), but this is creating coverity noise.
Additionally, revert the following commits that are not needed anymore:
6b6fa94c: Catch exceptions to please coverity
c2ed75fd: Fixup 6b6fa94c: coverity says there are more possible exceptions.
This commit is better viewed with 'git show -b'.
1.) Rename LYX_PATCH_VERSION to LYX_RELEASE_VERSION.
This matches the use in automake.
2.) Don't display LYX_DATE at configure time.
This value is evaluated later at build time
This is detected when an undo group is open and contains at east one
element. This means indeed that changes are in progress. Note that the
group is in general opened in GuiApplication::dispatch. The code there
is changed to ensure that the group is closed before updating the
screen.
This patch is experimental. It is expected to be replaced in master by
a more complete solution. It could in the meantime be backported to 2.3.x.
Fixes bug #11159.
As Kornel pointed out, it's possible to give a command sequence, or
multiple "-x" arguments, and carry out an operation without actually
giving LyX a filename argument. This will lead to cases like:
lyx -batch -x buffer-export
which don't do anything, but it's not catastrophic.
The reordering of the code was incorrect. The code calling Change::paintCue()
has to come last, since it depends on the change_drawn value.
Spotted by coverity.
