Module drawing 

The drawing utils for Plotter. Which handles the both low-level and high-level drawing.

For the low-level drawing abstraction, the module defines the DrawingBackend trait, which handles low-level drawing of different shapes, such as, pixels, lines, rectangles, etc.

On the top of drawing backend, one or more drawing area can be defined and different coordinate system can be applied to the drawing areas. And the drawing area implement the high-level drawing interface, which draws an element.

Currently we have two backend implemented:

• BitMapBackend: The backend that creates bitmap, this is based on image crate
• SVGBackend: The backend that creates SVG image, based on svg crate.
