Arguments

Name	Required	Default	Description
`x1`	yes	-	x of first point
`y1`	yes	-	y of first point
`cx`	yes	-	x of control point
`cy`	yes	-	y of control point
`x2`	yes	-	x of second point
`y2`	yes	-	y of second point
`stroke`	-	#000000	Stroke color
`fill`	-	#FFFFFF	Fill color
`weight`	-	1.00	Stroke weight (thickness)
`draw`	-	true	If false, return a list of points, and don't draw (stroke, fill & weight are ignored)
