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.
This will gracefully handle errors that prevent the file translation
by simply copying the file if they occur. This allows the build to
proceed and the logs to contain the error.
The BuildSteps folder now contains the CMake scripts that are
called during the build process as individual stages, while
the root CMakeModules directory contains the CMake files used
during the configuration phase.
