The faces to test the points against.
The points to sort.
OptionaltoleranceHow close to a boundary a point may be to count as on it, in model units.
OptionaluseWhen true, a point outside the face's bounding box, grown by gapTolerance, counts as
outside without the exact test; a quick reject for many points far from the face.
OptionalgapHow far beyond the bounding box a point may lie and still get the exact test when
useBndBox is on, in model units.
OptionalkeepWhen true, points inside a face are kept.
OptionalkeepWhen true, points on the boundary of a face are kept.
OptionalkeepWhen true, points outside a face are kept.
OptionalkeepWhen true, points the kernel cannot place inside, on or outside a face are kept.
OptionalflatWhen true, the kept points of all faces come back in one list; when false, one list per face in the order given.

shapes.face.filterFacesPoints, which sorts each point as inside, on the boundary of or outside each face.
