Closes the current subpath in this path, if there is one, by implicitly
adding a line segment from the current point to the starting point of
the subpath.
The endpoint of that line segment becomes the new current point
and the starting point of the next subpath.
closepath
does not complain if the current path is empty or already closed.

| Example: |
The program,
import yoix.stdio.*;
Path p;
moveto(x, y) = printf(" moveto(%.1f, %.1f);\n", x, y);
lineto(x, y) = printf(" lineto(%.1f, %.1f);\n", x, y);
closepath() = printf(" closepath();\n");
p.moveto(100, 100);
p.rlineto(100, 0);
p.closepath();
p.closepath();
p.rlineto(0, 100);
p.closepath();
printf("Output before CTM change:\n");
p.pathforall(moveto, lineto, NULL, NULL, closepath);
p.CTM.scale(2, 2);
printf("\nOutput after CTM change:\n");
p.pathforall(moveto, lineto, NULL, NULL, closepath);
prints something like
Output before CTM change:
moveto(100.0, 100.0);
lineto(200.0, 100.0);
closepath();
lineto(100.0, 200.0);
closepath();
Output after CTM change:
moveto(50.0, 50.0);
lineto(100.0, 50.0);
closepath();
lineto(50.0, 100.0);
closepath();
on standard output.
Notice how the coordinates changed after we scaled the
CTM
associated with the path, and pay attention to where the second line
segment started and the fact that the unnecessary
closepath
disappeared.
