public interface JaxoGrid
Grid: A grid "is" a collection of Points in the plane. An arbitrary point can be mapped to its closest point on the grid. This interface only knows about points on the grid, not about painting. In general, the grid is assumed to be infinite in all directions, not restricted to current bounding boxes or canvas size (of course, a specific grid could, e.g., claim that there are no grid points with negative coordinates).- Since:
