I've always envisioned that the samples should always be on a rectangular grid aligned with the coordinate axes of the complex plane. Any distortion or rotation should be done by a display process and not by the sampling process. ... Think of it like texture mapping. Your texture is always defined in a rectangular sample grid. Using the texture coordinates you can stretch and rotate it anyway you want.
But when you change the order to sampling / rotation, you don't get the same (pixel-by-pixel) picture, do you? Think of it like of doing inversion. If you reorder actions to sampling / inversion, you get a *very* sparse image. /charlie/
