CHANGED: Environment variables defined outside of KiCad will no longer
be saved in the settings file. Paths can be configured via
the Configure Paths dialog and those changes will be saved in
the settings file if the new path is different from the default
and the path variable was not defined in the system environment.
On Linux, the documentation and help files are potentially installed to
a non-standard location (i.e., outside of /usr/share/doc/kicad/). This
can be the case when, e.g., multiple versions of KiCad are installed in
parallel. Making KICAD_DOCS available at run-time is the only viable
solution to allow the applications to find the help files in this case.
Fixes https://gitlab.com/kicad/code/kicad/issues/7874
Introduce a new advanced config variable `KICAD_LIBRARY_DATA` which can
be used to move templates, symbols, footprints, and 3dmodels out of
`KICAD_DATA`. If not defined, everything is kept as before.
To facilitate this, PATHS::GetStockEDALibraryPath() is added. This
allows to differentiate code paths looking for EDA library data vs. code
paths looking for plugins, demos, and the like.
Thanks to Aimylios for the hints and suggestions with regards to the
stock EDA library data path handling on Windows and MacOS.
It is not always useful to distinguish between the cases when KiCad is
run from the build or the installation directory. E.g., the libraries
are generally not available in the same path as the code. Make the
evaluation of KICAD_RUN_FROM_BUILD_DIR conditional to accomodate these
scenarios.
Bitmaps are now identified by an enum class instead of by pointers.
Bitmap loading and caching is now handled by a class in common, and
we no longer compile most bitmaps into the binary, so there is no
longer a bitmaps static library.
Instead, bitmaps are archived to a .tar.gz file which is installed
in ${KICAD_DATA}/resources/images.tar.gz
The source PNGs are checked in to Git as the original CPP files were,
so that people can build without the required dependencies to convert
SVGs to PNGs.
Initial support is also added for dark theme icons, although this
is not yet exposed in the GUI.
Stubs are present for multi-resolution image resources, but this is
not fully-baked yet and could use some refinement.
