title: Parent call to Control.DrawToBitmap does not seem to respect clipping region set in child control
body: <p>I have created a UserControl which simply defines a new GraphicsPath and sets that to be the Region of the control. Its primary use is to act as a backdrop for other controls so typically the only thing set on it is BackColor. When I call DrawToBitmap on the control's parent, the child control is drawn as a rectangle rather than getting clipped to region I expected. Am I missing something here?</p>
  
  <p>Standard use of the control does not exhibit this problem. </p>
  
  <p>Also, I need to be able to draw this control to an image while it is not currently shown on screen. I have seen some workarounds would <em>could</em> have worked had I not had this additional requirement.</p>
