SimpleDraw is a new 2D graphics drawing product. We are asked to write the core engine of the graphics system.
You must create software that implements the abstraction of a drawing. A drawing is defined as a 2D space that contains an unlimited number of drawing primitives. There are 2 drawing primitives defined:
1. An ellipse
2. A rectangle
Your software must represent a drawing containing an unlimited number of drawing primitives. Each primitive has a location (x, y coordinate) and a size (width, height). The drawing should be able to determine the size of the total drawing and should be able to display the drawing in the following format:
Drawing Name: Drawing 1
Total number of primitives: 59
Total size: 1020, 2780
Primitive 1: Ellipse
Location: 0, 10
Size: 100, 400
Primitive 2: Rectangle
Location: 30, 78
Size: 500, 800
.....
Primitive 59: Ellipse
Location 100, 600
Size: 300, 333
