  Comments: Initialize GLUT window, callbacks, and pixel draw buffer.

            The program initializes program for drawing lines. The
            user can operate the line tool using the following
            interface:

	    Mouse buttons

	         left -- triangle vertex points 
		 right -- line vertex points
		 
	    Keyboard input

                 c,C -- clear pixel buffer
		 
                 r,R -- change red amount of draw color
                 g,G -- change green amount of draw color
                 b,B -- change blue amount of draw color

	         l,L -- display line test patterns
	         t,T -- display triangle test patterns
	         s,S -- toggle smooth shading

		 <,> -- decrease / increase number of steps for line and triangle test cases
		 q,Q,<esc> -- quit line draw tool
