8a2a9dba2f Eradicated admesh from TriangleMesh:
TriangleMesh newly only holds indexed_triangle_set and
TriangleMeshStats. TriangleMeshStats contains an excerpt of stl_stats.
TriangleMeshStats are updated when initializing with indexed_triangle_set.

Admesh triangle mesh fixing is newly only used when loading an STL.
AMF / 3MF / OBJ file formats are already indexed triangle sets, thus
they are no more converted to admesh stl_file format, nor fixed
through admesh repair machinery. When importing AMF / 3MF / OBJ files,
volume is calculated and if negative, all faces are flipped. Also
a bounding box and number of open edges is calculated.

Implemented its_number_of_patches(), its_num_open_edges()
Optimized its_split(), its_is_splittable() using a visitor pattern.

Reworked QHull integration into TriangleMesh:
    1) Face normals were not right.
    2) Indexed triangle set is newly emitted instead of duplicating
       vertices for each face.

Fixed cut_mesh(): Orient the triangulated faces correctly.

58d8ab3dea Removed the PRUS format parser. WIP: admesh eradication:
stl_stats are newly only accessed by TriangleMesh::stats(),
most of the direct access to TriangleMesh::stl is gone with the exception
of parsing input files (3MF, AMF, obj).

1c76df89ea Fix of paint on supports don't work for object that has been scaled up #6718
The triangle-ray intersection function used a hard coded epsilon,
which did not work for triangle meshes, that were either too small
or too large. Newly the epsilon may be provided to the AABBTreeIndirect
search functions externally and IndexedMesh calculates a suitable
epsilon on demand from an average triangle mesh edge length.

0d70a2be69 Renamed create_face_neighbors_index() to its_face_edge_ids().
Renamed its_create_neighbors_index() / its_create_neighbors_index_par() to its_face_neighbors() / its_face_neighbors_par().
New variant of its_face_edge_ids() to create edge IDs from face neighbors.
Fixed some incorrect use of _NDEBUG, it should be NDEBUG.
PrintObject::slice_support_volumes() returns newly Polygons, which are cheaper than ExPolygons.
Updated SeamPlacer and SupportMaterial to use regions defined as Polygons, not ExPolygons.
TriangleSelector::get_facets_strict() returning a patch with T-joints retriangulated.
New slice_mesh_slabs() - slicing projections of a triangle patch into top / bottom layers of slices, for MMU top / bottom segmentation.
TriangleMeshSlicer - use 64 mutexes instead of one when scattering sliced triangles into layers. This makes a big difference on modern many core desktop computers.
When applying MM segmented regions to input regions, the split regions are now re-merged with 10x higher positive offset epsilon to avoid creating gaps.
When testing for existence of paint-on supports or seam, use a more efficient has_facets() test, which does not deserialize into the expensive TriangleSelector tree structure.
GLIndexedVertexArray newly uses Eigen::AlignedBox<float, 3> for efficiency instead of our double based BoundingBoxf3.
Improved MMU painting refresh speed by optimizing generation of the vertex buffers.
Refactored MMU segmentation - projection of painted surfaces from top / bottom.
	1) Parallelized.
	2) Using the new slice_mesh_slabs() instead of projecting one triangle by the other and merging them with Clipper.

4e11552da9 Spiral vase improvements and bugfixes.
Fixes Connecting / expanding Bottom Layers to Vase Perimeter #253
Fixes Slicing error in vase mode #452
Fixes Slicing Issue (Vase Mode, 0.6mm dmr nozzle) #1887
Fixes Top fill pattern isn't used in spiral vase mode #2533
Fixes Cisar's vase doesn't slice correctly, creates artefacts #3595

When the model is sliced, all the contours are newly oriented
counter-clockwise (even holes), merged and then only the largest area
contour is retained. In perimeter generator, if the largest contour
splits into multiple perimeters, newly only the largest area perimeter
is retained in spiral vase mode. These two changes solve #3595 and similar.

The infill is newly calculated only for the bottom solid layers
if the spiral vase mode is active (removes various unwanted infill
along the vase walls), and the last bottom solid layer is switched
to a top solid pattern (solves #2533).

The thin walls are newly enforced to be disabled in spiral vase mode,
and the "ensure vertical shell wall" is enforced in spiral vase mode
to extend the bottom of the vase to the vase hull (fixes #253).
