Fixing projection of bottom surfaces in MM segmentation and for
support blockers / enforcers.
All slicing functions shall produce consistent results with the same mesh, same transformation matrix and slicing parameters.
Namely, slice_mesh_slabs() shall produce consistent results with slice_mesh() and slice_mesh_ex() in the sense, that projections made by
slice_mesh_slabs() shall fall onto slicing planes produced by slice_mesh().
Before this commit, slice_mesh_slabs() projected bottom facing faces upwards to its coplanar slicing plane,
which is different from how slice_mesh() or slice_mesh_ex() work, leading to ignored support enforcer / blocker strokes.
