NEW IN 10.0.0

     BREAKING: a body is measured as its material.
     - GeoSolid3.GetVolume(), GetSurfaceArea() and GetCentroid(), each also within a tolerance, measure the faces with
       every opening cut out, the walls of the openings part of the surface, and TryGetVolume says whether the volume
       can be trusted: every opening cut out and the material closed. The cut is made once for a tolerance and kept by
       the body, and GetMassProperties and Measure3 measure the same cut. A body without openings, as every part
       GeometryHelper.TeklaConvert reads, is measured by its faces at once.
     - Removed: GeoSolid3.Volume, SurfaceArea and Centroid, which read the faces alone, duct and all; NetVolume, which
       took each opening's whole volume off, past the body or not; and GetNetVolume(). GetSignedVolume() is internal:
       TurnOutwards() gives the body wound outwards, its openings too.

     NEW
     - GeoTriangle2, the triangle of the plane, in the whole matrix of the plane, answered by Core.Triangle2.
     - TriangulateSurface on GeoPolygon2, GeoFace2, GeoPolygonArc2, GeoRectangle2 and GeoCircle2.
     - GeometryHelper.Meshing: ToMesh breaks a shape of the plane into a GeoMesh2, of triangles, of the cells of a grid
       as formwork panels or tiles are laid, of strips or of convex pieces, as MeshOptions says; and a shape of space
       into a GeoMesh3, its grid placed by MeshPlacement3. GeoRectangle2.Divide.
     - ToCells on GeoSolid3, GeoObb3 and GeoAabb3 cuts a body into a GeoCellGrid3 of closed GeoCell3s, by CellOptions3.
     - Measure3 measures volume, mass, centroid and area by the method asked, VolumeMethod Fan, Surface or FlatFaces,
       and Compare sets every method side by side.

     FIXED
     - A body wound inwards came out of the booleans, TryCutOpenings, TrySplitBy, TryGetContact and the clash check
       wrong; each turns its bodies outwards first.
     - Two slabs from Tekla Structures, one wrapping the other's corner at a slant of 0.32 milliradians, share a wedge
       of 15.79 million cubic millimetres, which the difference took none of and the common part lost an eighth of.
       Two planes are one now only where they stand together over what they cut, and a cell a plane could not cut is
       judged on both sides of it.
     - GeoSolid3.TrySplitBy, Section and the cells cut from a body: a plane parting a body without crossing it, through
       a corner, at a slant across an edge two faces share, beside a rim bridged across, through a face a hair out of
       flat; a hole on the rim of its piece came back as material.
     - GeoFace3 and GeoSolid3 Locate, Contains, DistanceTo and GetClosestPointOnBoundary read a face's holes in the
       plane of its boundary; a point of a body thinner than four point tolerances is placed by the solid angle.
     - Areas and centroids of GeoPolygon2 and GeoPolygonArc2 far from the origin; ConvexHull3 and GeoObb3.Fit on a
       hull with a tiny face; Merge3.CoplanarFaces on faces a hair turned; TriangulateSurface within a tolerance finer
       than the global one; GetMassProperties of a body its openings take whole.

     CHANGED
     - The package depends on no other package: Clipper2 2.0.0's clipping engine is compiled in, internal, and the
       package carries THIRD-PARTY-NOTICES.md. A project that used Clipper2 through GeometryHelper references the
       Clipper2 package itself now. Where its sweep fails, the plane gives no region and a warning.
     - Separating a body into pieces, IsClosed and cutting by a plane pair edges along the axis that leaves the fewest
       pairs: a drum of 4 096 sides took eleven seconds and takes four hundredths.
