Prototype of the callback to iterate through the operations of
a path.
For each operation, the callback is given the op itself, the points
that the operation is applied to in pts, and a weight for conic
curves. The n_pts argument is somewhat redundant, since the number
of points can be inferred from the operation.
Each contour of the path starts with a GSK_PATH_MOVE operation.
Closed contours end with a GSK_PATH_CLOSE operation.
