Worked on the rulers and zooming for CC today. Mainly, it now allows you to scale your image, to focus on specific areas. It also now can handle scrolling right and left, so you don't have to make your window larger than your pattern. The area that has the most trouble at this point is the rulers. They aren't quite in sync with the image, but that is tomorrow's primary goal (though it may take into Monday since Friday is my half-day).
