Forgot to mention: If you add a "border();" command as a guide, the 
picture border drawn around the figure will have the specified size.
To get more detailed information, you can use

  grid(n, n);

*before* you set the camera location. For example,

  picture(P(-1,-1), P(1,1), "6 x 6in");
  grid(12,12);
  camera.at(...);

draws a grid of 1/2-inch squares under the figure. (It may help to draw 
the grid in a different color, say red. :)
