-- The input brush must have face windings.
-- The input brush must be a brush with faces that do not intersect.
-- The input brush does not have to be convex.
-- The vertex will not be moved if the movement either causes the
- brush to have faces that intersect or causes the brush to be
- flipped inside out.
- (For instance a tetrahedron can easily be flipped inside out
- without having faces that intersect.)
-- The created brush does not have to be convex.
-- Returns true if the vertex movement is performed.
