Write a routine to draw a square with a side length A centered on the display. The value of A should be given as an argument to the routine. Test this routine by drawing a picture with four squares of different sizes. Suppose that MOVE and LINE displays file instructions each take 4-bytes of storage. (i) How much display file storage is required for 1000 independent line segments? (ii) If the image is placed in a 1024 1024, 1-bit per pixel frame buffer, how much frame buffer memory is required. Show how reflections in the line y = x and in the line y = -x can be performed by a scaling operation followed by a rotation. Show that a rotation about the origin can be done by performing three shearing transformations.
