[tremor] Lookup-tables for window function

[Erik Montnémery]

How are the lookup tables for the window shapes generated? According to the documentation the window shapes are given by y=sin(2*pi*sin^2(x/n)), where n is the window length and x=[0..n/2] but as far as i can tell this is not the case. 
My reason for asking is that I need to minimize memory usage and would like to use linear interpolation of longer windows from shorter shapes instead of storing them in RAM.
