title: HitTest region around a PathGeometry
body: <p>I draw curves on a canvas using wpf <code>PathGeometry</code>'s, directly via <code>DrawingContext</code>.  </p>
  
  <p>The <code>HitTestResultBehavior</code> shows that the bounding box of the curve is the whole rectangle enclosing the curve, i.e. TL, TR, BL, BR.</p>
  
  <p>I am considering cutting the curve in smaller parts, drawing them seperately, so that the HitTest region around the curve becomes more fitting to the form of the curve itself.</p>
  
  <p>Is there perhaps a general approach to this problem that you know of?</p>
