Implement Liang-Barsky Line Clipping algorithm. Your algorithm should take inputs: starting and ending coordinates of the line and xwmin, xwmax, ymin, and ymax of the clipping window. The output: the line is completely visible or partially visible or completely invisible. 1. you can use opengl to draw the line and the dlipping window. 2.] Check for the case when the line intersects with the corner of the clipping window
