- * cairo_path_data_t:
- *
- * #cairo_path_data_t is used to represent the path data inside a
- * #cairo_path_t.
- *
- * The data structure is designed to try to balance the demands of
- * efficiency and ease-of-use. A path is represented as an array of
- * #cairo_path_data_t, which is a union of headers and points.
- *
- * Each portion of the path is represented by one or more elements in
- * the array, (one header followed by 0 or more points). The length
- * value of the header is the number of array elements for the current
- * portion including the header, (ie. length == 1 + # of points), and
- * where the number of points for each element type must be as
- * follows:
- *
- * <programlisting>
- * %CAIRO_PATH_MOVE_TO: 1 point
- * %CAIRO_PATH_LINE_TO: 1 point
- * %CAIRO_PATH_CURVE_TO: 3 points
- * %CAIRO_PATH_CLOSE_PATH: 0 points
- * </programlisting>
- *
- * The semantics and ordering of the coordinate values are consistent
- * with cairo_move_to(), cairo_line_to(), cairo_curve_to(), and
- * cairo_close_path().
- *
- * Here is sample code for iterating through a #cairo_path_t:
- *
- * <informalexample><programlisting>
- * int i;
- * cairo_path_t *path;
- * cairo_path_data_t *data;
- *
- * path = cairo_copy_path (cr);
- *
- * for (i=0; i < path->num_data; i += path->data[i].header.length) {
- * data = &path->data[i];
- * switch (data->header.type) {
- * case CAIRO_PATH_MOVE_TO:
- * do_move_to_things (data[1].point.x, data[1].point.y);
- * break;
- * case CAIRO_PATH_LINE_TO:

- * break;
- * case CAIRO_PATH_CLOSE_PATH:
