Drawing panel

Basic container for 2D drawing. A drawing panel is a view element able to display drawable objects within a rectangular region of the plane in which it defines a world coordinate system in user-provided coordinates. Drawables, or drawing elements, are graphical objects which draw themselves (in different forms) in a given position and with a given size within a drawing panel.
