/** This makes a cube that projects a different silhouette
    along 3 axes, and renders it in Waveform .obj format for 3-D printing.
    This version can take text for each axis. (They can
    be different sizes; this resizes them to 400x400 pixels.) The white
    parts will be "cut out" of the cube.
