Subject: Graph + GraphUI: Consolidate Vertex: Drop SVertex and factory, use
 Vec[234]f instead of float[] and remove unused VectorUtil methods

After Matrix4f consolidation and proving same or better performance on non array types,
this enhances code readability, simplifies API, reduces bugs and may improve performance.

GraphUI:
- Have RoundButton as a functional class to make a round or rectangular backdrop,
  i.e. impl. addShapeToRegion() via reused addRoundShapeToRegion()
