curveVertex() with fill()

curveVertex() and fill() should not form a solid outline.

This generates a shape using curveVertex() with fill(). The end result should NOT be a completely connected (outlined) box. The line should only go through the specified coordinates. The expected result is shown via image on the right.

Source Code:

size(150,150,P3D);
background(128);
fill(255);

beginShape();
  curveVertex(5,26,0);
  curveVertex(5,26,0);
  curveVertex(73,24,0);
  curveVertex(73,61,0);
endShape();

beginShape();
  curveVertex(5,26,0);
  curveVertex(73,24,0);
  curveVertex(73,61,0);
  curveVertex(73,61,0);
  curveVertex(15,65,0);
endShape();
