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).
