  And add to that all the other type of projections: spherical,
ultra_wide_angle, panoramic, cylindrical, fisheye... Not to talk about
camera ray perturbation (with a normal block).
  The excellent thing about raytracing is that implementing all those types
of projections is laughably easy (while in scanline-rendering it's extremely
difficult to do without serious compromises). The negative side is that it
disallows any optimizations typical to scanline-rendering.
