It’s time to add curves to the graphics engine. Everything will work as before, we will have three more shapes to draw.

1. Add the following commands to the parser
   • circle: adds a circle to the edge matrix - takes 4 parameters: cx, cy, cz, r
   • hermite: adds a hermite curve to the edge matrix - takes 8 parameters: x0, y0, x1, y1, rx0, ry0, rx1, ry1
   • The curve is between points (x0, y0) and (x1, y1).
   • rx0, ry0 and rx1, ry1 are the rates of change at each endpoint * bezier: adds a bezier curve to the edge matrix - takes 8 parameters: x0, y0, x1, y1, x2, y2, x3, y3
   • This curve is drawn between (x0, y0) and (x3, y3).
   • (x1, y1) and (x2, y2) are the influence points for the curve.
2. For help creating your own image, you might want to use the following graphs:

3. Makefile specifications:
   • If you look at skill 1, you will see that a 4 involves having multiple targets that may not be directly related to building your project. One initial suggestion is to have a clean target that gets rid of unwanted temporary compiler/interpreter byproducts. In addition, you must have the following targets:
     • The default target should run (and appropriately compile etc.) the test script that I have provided.
     • custom: This target should run your program like the default target, but should use your custom image script instead.
