BezierCurve:render
Get a list of coordinates to be used with love.graphics.line.

This function samples the Bézier curve using recursive subdivision. You can control the recursion depth using the depth parameter.

If you are just interested to know the position on the curve given a parameter, use BezierCurve:evaluate.
coordinates = BezierCurve:render( depth )
depth (5) number Number of recursive subdivision steps.
coordinates table List of x,y-coordinate pairs of points on the curve.
