Scan$-$convert lines using Bresenham$$s line algorithm.

Display$\_1$ of the sample program $$Lab$\_2\_$Shell$$ shows an example of drawing a line with a slope between $0$

and $1$ using Bresenham$$s line algorithm. Use this example to draw three additional lines defined below:

a line from $(0,200)$ to $(300,0)$;

a line from $(0,0)$ to $(200,300)$; and

a line from $(0,300)$ to $(200,0).$

Place your drawing code in the drawing function of Display$\_1($Display$\_1$::Draw$(...))$ in the sample program

$$Lab$\_2\_$Shell$.$ Your drawing results should show when the key $1$ on the keyboard is pressed.
