/* 6.914, Example 0.7

The custom shape tool is pretty simple to work with, but can
produce interesting and cool-looking results. Basically, it
looks like this:
  beginShape();
  vertex(x1, y1);
  vertex(x2, y2);
  vertex(x3, y3);
  // as many vertices as you want here
  endShape();
  
Every vertex (except the last one) will have a line between
itself and the one after it. The simplest parameter you can
give to this tool is changing the last line to 
  endShape(CLOSE);
which will make a line between the last point and the first one.

The following properties are basically independent for each shape:
stroke (or noStroke), fill (or noFill), and CLOSE. 
(Of course, if you have noStroke, it doesn't matter whether you pass 
CLOSE as an argument.)

  vertex(80, 130);
