curveDetail example uses default renderer

This is the example for curveDetail:

The thing is, the example should not use the default renderer cause curveDetail does not work there. This is what it looks like when switching to P2D (as intended):

Also it makes more sense to have all draw code in setup, cause now the first curve will become white after the first frame, and the become all ugly from drawing on top of each other.

Hi Doeke you're absolutely correct! If you want to make a pull request for this I will happily merge it.

The following code works as intended:

void setup(){
  size(400,400,P2D);
}

void draw(){
  curveDetail(1);
  drawCurves(-60);
  stroke(126);
  curveDetail(2);
  drawCurves(0);
  stroke(255);
  curveDetail(4);
  drawCurves(60);
  noLoop();
}

void drawCurves(float y) {
  noFill();
  curve( 20, 112+y,  20, 112+y, 292, 104+y, 292, 252+y);
  curve( 20, 112+y, 292, 104+y, 292, 252+y, 60, 268+y); 
  curve(292, 104+y, 292, 252+y, 60, 268+y, 60, 268+y);
}
