public abstract class ShapeDrawer
extends Object

Base class for all shape drawer, classes which must designer on canvas the shape.
A tile is always a square and for some shapes is divided in 4 sections and not all sections are designed.
A tile is designed as following:

 +---------+---------+
 |         |         |
 |         |         |
 |         |         |

Depending on shape, the parts can be designed or not.
