• Graphic lib has a new function that can calculate point on a quadratic bezier curve which can be use to draw quarter circle.

    Combine four of them will draw a rectangle with rounded corners.

    
    g.clear();
    
    function RectRnd(x1,y1,x2,y2,r) {
          pp = [];
          pp.push.apply(pp,g.quadraticBezier([x2-r­,y1, x2,y1,x2,y1+r]));
          pp.push.apply(pp,g.quadraticBezier([x2,y­2-r,x2,y2,x2-r,y2]));
          pp.push.apply(pp,g.quadraticBezier([x1+r­,y2,x1,y2,x1,y2-r]));
          pp.push.apply(pp,g.quadraticBezier([x1,y­1+r,x1,y1,x1+r,y1]));
          return pp;
    }
    
    function fillRectRnd(x1,y1,x2,y2,r) {
          g.fillPoly(RectRnd(x1,y1,x2,y2,r),1);
    }
    
    function drawRectRnd(x1,y1,x2,y2,r) {
          g.drawPoly(RectRnd(x1,y1,x2,y2,r),1);
    }
    
    drawRectRnd(10,10,150,50,5);
    fillRectRnd(10,60,150,120,5);
