- Floating point gives too much trouble for pixel-perfect connections.
- Rectangle marcher test uses new inner and outer radius.
  This changes the affected set pixels and coverage of pixels.
- Use a Position2D to pass the center point into Marching Rectangles.
- Add a relative Position2D for specifying the starting pixel with MarchingRectangles.
- Handle empty graphics in the solver by allowing -1 as value for a variable.
