Returns shape points of an ellipse. They can be used with xxx_extrude modules of dotSCAD. The shape points can be also used with the built-in polygon module.
axes: 2 element vector
[x, y]where x is the semi-major axis and y is the semi-minor axis.
$fn: The shape created by this function can be viewd as
resize([x, y]) circle(r = x)(but not the real implementation inside the module) so you can use these global variables to control it. Check the circle module for more details.
