SWFShape->drawCurve
for those new this all this, "anchor" is where you want to end up and "control" is the point you would go to if you were drawing a square.
for example, this would draw a quarter circle
<?php
$s->movePenTo(100, 100);
$s->drawLineTo(200, 100);
$s->drawCurveTo(200, 200, 100, 200);
$s->drawLineTo(100, 100);
?>
SWFShape->drawCurveTo

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 ).
