An arc moved only when its centre was in the window, so stretching a rounded end left the arc where it was or blew it up. Its ends now decide: both in move it, one in moves that end while the arc keeps its height (sagitta) over the new chord. Polyline arc segments keep their height the same way instead of their bulge, spline control and fit points in the window move, and 3D polylines and points stretch too. Old-style polylines were tested in X/Z. The preview moved the tessellated points that happened to be in the window, which bent arcs out of shape; it now draws the stretched entities through one shared function the commit also uses, via a new preview_entities hook, and hides the originals while it shows.
