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).
