The bake is covered in the libslic3r suite, but nothing carried its
result through the slicer - where a mesh it cannot use shows up as a
crash or as a print with no toolpaths, which is what was reported on
macOS and Linux.
Paints a cube, bakes it as the gizmo commits it (mesh replaced, hull
recomputed, paint cleared), slices it and checks the G-code has
toolpaths and layers. Once under its budget and once capped, since a
capped bake also goes through the simplification and the repair.
