It does not. These apodization functions are only used when
requested by the user, and according to my measurements they are
not the best choice (i.e., there are window functions that
perform better on most material) Still, as they are in the
codebase, I thought fixing them would be a good idea.

Thanks for the lead! I'll take a look. I could zero the function
below a certain limit as well, looks like that solves it as
well. Not that it is very important: those windows don't seem to
perform very well anyway.
