PointState

A degenerate state representing a single point

Used to explicitly control where shapes disappear to or appear from during M→N morphing transitions. Unlike implicit zero-states, PointState gives users full control over: - Exact disappearance location (x, y) - Opacity behavior during transition - Visual representation (nothing rendered at t=1.0) During morphing, shapes smoothly collapse to (or expand from) the point location. The opacity can be set to 0.0 for fade-out effects, or 1.0 to maintain visibility until the final moment.
