%Docstring
Construct a circular string from arrays of coordinates. If the z or m
arrays are non-empty then the resultant circular string will have z and
m types accordingly.
This constructor is more efficient then calling
:py:func:`~QgsCircularString.setPoints`.
If the sizes of ``x`` and ``y`` are non-equal then the resultant
circular string will be created using the minimum size of these arrays.
.. warning::
It is the caller's responsibility to ensure that the supplied arrays
are of odd sizes.

%Docstring
Creates a circular string with a single arc representing the curve from
``p1`` to ``p2`` with the specified ``center``.
If ``useShortestArc`` is ``True``, then the arc returned will be that
corresponding to the shorter arc from ``p1`` to ``p2``. If it is
``False``, the longer arc from ``p1`` to ``p2`` will be used (i.e.
winding the other way around the circle).
