Edge Tracer

UPDATED!! Does a really impressive Edge Trace operation on a picture. It has 2 modes of Edge Tracing. B&W Edge Trace: Any pixel with a difference larger than the Edge Threshold Value is set to Black GrayScale Edge Trace: Also shows how much difference is there. Now has 2 modes of edge tracing. One is more accurate. The other produces finer and sharper edge traces though less accurate. (Thanks for your feedback Rang3r!!) Any comments for improvement?
