Penrose tribar

Since the {{polygon}} template doesn't currently support the fill (only the stroke), while the {{rectangle}} template does support the fill, each of the 3 shaded areas is made up of 2 skewed rectangles, the second of which is properly rotated and translated to get the proper shape for the shaded area.
