When only anchors of a path or compound path move, the area an edit changed is now the box of the segments that start or end at a moved anchor (and the line that closes an open subpath's fill at a moved end), before and after, grown by the farthest the strokes reach. The canvas then draws that part of the frame again instead of the whole object. Objects with a non-solid paint, dashes, a width profile, arrowheads, a brush, effects or an opacity mask still count whole. At 1600 x 1200, single-threaded, the frame after one anchor of a filled closed path moves takes 16.6 million CPU cycles instead of 56.4 million with 50,000 anchors, and 65.6 million instead of 180.0 million with 200,000 anchors.
