swfshape->drawcurve() draws a quadratic curve (using the current line style,set by swfshape->setline()) from the current pen position to the relative position (anchorx ,anchory ) using relative control point (controlx ,controly ). That is, head towards the control point, then smoothly turn to the anchor point.
With 6 parameters, it draws a cubic bezier to point (x+targetdx , x+targetdy ) with control points (x+controldx , y+controldy ) and (x+anchordx , y+anchordy ).
