Using std::any from C++17 allows for proper type handling in the
parameter field, removing the need for casting to void* and then casting
the void* to the desired type.
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.
* Frames moved: cvpcb, cvpcb footprints frame, gerbview, pagelayout editor
This also introduces new EDITOR_CONDITIONS that are used to set the
conditions of very common editor settings.
Also, some IDs were converted to tools in the pagelayout editor.
It's a bit of a hack because they're statically initialized and
so we can't make use of the _() macro. We do still want it in the
code, however, because the string harvesting is based off of it.
