Returns shape points of a rounded square or rectangle. They can be used with xxx_extrude modules of dotSCAD. The shape points can be also used with the built-in polygon module.
size: Accepts single value, square with both sides this length. It also accepts 2 value array
[x, y], rectangle with dimensions
corner_r: The corner is one-quarter of a circle (quadrant). The
corner_rparameter determines the circle radius.
$fn: Used to control the four quadrants. Check the circle module for more details. The final fragments of a circle will be a multiple of 4 to fit edges.
