* Your code should draw a line from (x0, y0) to (x1, y1) using the color rgb into buf.
* You may assume that the points are within the buffer.
* To set a pixel at location (x,y) to color rgb just use
* buf.setRGB(x,y,rgb);
* hint: You will probably need to handle multiple cases. There are eight octants to may
* need to consider, but it can be solved using just two cases.
