The raytracing module should support clipping or finite apertures. There is interaction between this and #68, since an aperture limit on a surface would be relevant to how the surface is drawn in a plot.
I'm not sure at the outset what the best way to support apertures is. It may be that each surface should include a function which defines the aperture (so, partial(circle, r=aperture_radius) would be the most common). Or simple rmin/rmax, xmin/xmax to draw simple apertures.
