/**
* 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:
* do_line_to_things (data[1].point.x, data[1].point.y);
* break;
* case CAIRO_PATH_CURVE_TO:
* do_curve_to_things (data[1].point.x, data[1].point.y,
* data[2].point.x, data[2].point.y,
* data[3].point.x, data[3].point.y);
* break;
* case CAIRO_PATH_CLOSE_PATH:
* do_close_path_things ();
* break;
* }
* }
* cairo_path_destroy (path);
