A GraphicsPath is a representation of a geometric path, essentially
a collection of lines and curves.  Paths can be used to define
areas to be stroked and filled on a GraphicsContext.

.. class:: GraphicsPath(GraphicsObject)

   A GraphicsPath is a representation of a geometric path, essentially
   a collection of lines and curves.  Paths can be used to define
   areas to be stroked and filled on a GraphicsContext.

   .. method:: __init__(self)


   .. method:: AddArc(self, x, y, radius, startAngle, endAngle, clockwise=True)

      Adds an arc of a circle centering at (x,y) with radius, from
      startAngle to endAngle.


   .. method:: AddArcToPoint(self, x1, y1 , x2, y2, radius )

      Adds a an arc to two tangents connecting (current) to (x1,y1)
      and (x1,y1) to (x2,y2), also a straight line from (current) to
      (x1,y1)


   .. method:: AddCircle(self, x, y, radius)

      Appends a new closed sub-path as a circle around (x,y).


   .. method:: AddCurveToPoint(self, cx1, cy1, cx2, cy2, x, y)

      Adds a cubic Bezier curve from the current point, using two
      control points and an end point.


   .. method:: AddEllipse(self, x, y, w, h)

      Appends an ellipse fitting into the given rectangle as a closed sub-path.


   .. method:: AddLineToPoint(self, x, y)

      Adds a straight line from the current point to (x,y)


   .. method:: AddPath(self, path)

      Appends the given path to this path.


   .. method:: AddQuadCurveToPoint(self, cx, cy, x, y)

      Adds a quadratic Bezier curve from the current point, using a
      control point and an end point.


   .. method:: AddRectangle(self, x, y, w, h)

      Adds a new rectangle as a closed sub-path.


   .. method:: AddRoundedRectangle(self, x, y, w, h, radius)

      Adds a new rounded rectangle as a closed sub-path.


   .. method:: Clone(self)

      Return a new path initialized with the current contents of this path.


   .. method:: CloseSubpath(self)

      Adds a line segment to the path from the current point to the
      beginning of the current sub-path, and closes this sub-path.


   .. method:: Contains(self, x, y, fillStyle=wx.ODDEVEN_RULE)

      Returns ``True`` if the point lies within the path.


   .. method:: GetBox(self)

      Return the bounding box enclosing all points on this path.


   .. method:: GetCurrentPoint(self)

      Gets the current point of the path, which is conceptually the
      final point reached by the last path operation.


   .. method:: GetNativePath(self)

      Returns the path as a ``cairo.Path`` object.


   .. method:: MoveToPoint(self, x, y)

      Begins a new sub-path at (x,y) by moving the "current point" there.


   .. method:: Transform(self, matrix)

      Transforms each point in this path by the matrix
