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.
