     swfshape->drawcurveto() draws a quadratic curve 
     (using the current line style, set by swfshape->setline())
     from the current pen position to 
     (anchorx,anchory) 
     using (controlx,controly)
     as a control point. That is, head towards the control point, 
     then smoothly turn to the anchor point.
