     The <function>swf_shapecurveto</function> function draws a
     quadratic bezier curve from the current location, though the x
     coordinate given by <parameter>x1</parameter> and the y 
     coordinate given by <parameter>y1</parameter> to the x
     coordinate given by <parameter>x2</parameter> and the y coordinate
     given by <parameter>y2</parameter>.  The current position is then
     set to the x,y coordinates given by the <parameter>x2</parameter> and
     <parameter>y2</parameter> parameters
