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.
With 6 parameters, it draws a cubic bezier to point (targetx , targety ) with control points (controlx , controly ) and (anchorx , anchory ).
