However, according to cairo documentation:
The behavior of cairo_close_path() is distinct from simply calling cairo_line_to() with the equivalent coordinate
in the case of stroking. When a closed sub-path is stroked, there are no caps on the ends of the sub-path. Instead,
there is a line join connecting the final and initial segments of the sub-path.
The correct fix will be possible when cairo introduces methods for moving without
ending/starting subpaths, which we will use for skipping invisible segments; then we
will be able to use cairo_close_path here. This issue also affects ps/eps/pdf export,
