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).
