Graphic memory manager was changes so that it can work with any object that implements a specific interface (MemoryManaged). With this it will be possible to use other objects (that take a lot of memory) to be managed by the manager. It is also a first step to move memory managin responsibilities away from Graphic and move it into the specific objects instead (BitmapEx, Animation and VectorGraphic).
