Vertex3D: app finished!
Vertex3D: fix region size.
Vertex3D: Add the new 'Grid' bitmap option!
beginnings of support for drawing the Region in Vertex3D app.
re-add center to Vertex3D
Re-write Vertex3D to provide similar functionality to Fragment3D (displaying the center and region bitmaps still missing)

Progress with Vertex3D
Vertex3D: add configurable center
Vertex3D almost finished - there's still a problem when parts of Cubes get culled if the Object gets Deformed or Distorted to the left (curiously only the 'left' direction seems to trigger this!)
Skeleton of the new App: Vertex3D. So far just a copy of Matrix3D.
