Use imroved Arc API (arc can only represent a circular section, and setting
two endpoints could cause problems with endpts and center colinear and radii
from center to two endpoints differing). New API uses a center, start point,
normal and sweep angle. Also change Line to support polylines: protocol is
changed to require a Tcl list for point coordinates instead of a fixed 2
endpoints.
