Adds to self the segment of path from start to end.
If start is equal to or after end, the path will first add the
segment from start to the end of the path, and then add the segment
from the beginning to end. If the path is closed, these segments
will be connected.
Note that this method always adds a path with the given start point
and end point. To add a closed path, use gsk.path_builder.PathBuilder.addPath.
