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