Why? Does it not support moving emitter-points directly?

Those puffs are not caused by aliasing. Each puff is only one particle, not
a group of particles. They're caused by a low particle_frequency. If the
particle_frequency were high enough, there would be no visible puffs, even
if the particle_frequency were higher than the calculation frame-rate.

Moving particle-emitters are already supported in my system, but not moving
environment-objects.

I think it would be very useful to be able to interpolate transformations. I
have often done similar things myself (in POV-script).

Not in the current version, according to the documentation, but it does say
that it will be available in future versions...
