+Returns the TikZ code that builds a path out of the current set object as a string formatted by the L<LaTeX::TikZ::Formatter> object C<$formatter>.
+The current evaluation context is passed as the L<LaTeX::TikZ::Context> object C<$context>.

+C<begin>
+
+Returns a L<LaTeX::TikZ::Point> object pointing to the beginning of the path, or C<undef> if this path has no beginning.
