The methods described below can be used to add more details to drawings created by the following visualization methods:

Surface::VISUAL_FACE_LATTICE

MORSE_MATCHING (%Visual::Lattice::decorations)
Add the MORSE_MATCHING to the visualization of the face lattice of the surface.
FACES ("PROPERTY_NAME" or [ Faces ], %Visual::Lattice::decorations)
Add distinguished faces with different graphical attributes NodeColor and NodeStyle

Each auxiliary method always returns the visual object it was called with ($this), which makes it easy to build longer method chains of the kind: VISUAL->DIRECTED_GRAPH->VERTEX_COLORS .
