to remove the power-of-two issue. It also supports real->complex and

to add extra options for that, of course.
Hmmmmm. Can't all those things already be done using the imfourier(...)
routine?
Direct real->complex and complex->real transforms use half the memory
and run at twice the speed, so you can work on larger datasets. I
don't know how useful that difference would be in this context though.
