I wouldn't worry about the aliasing, since volume visualization
isn't very quantitative. Its just a colored fog.

You could use a test to only resample beyond a certain degree
of out-of-square. Also, give users a choice of other techniques,
such as interactive iso-surfaces, that they can use when volume
visualization isn't effective.

Also, I'd still be interested to see a JPEG or GIF of one of
your problem images.
