What happens when the window is resized? It seems like we need to re-calculate all lengths that have already been computed, which in effect means re-applying all CSS properties continuously during a window resize (ie. for every new width which the window size is changing). That seems like it would be really computationally expensive.

Code style wise, it would be nice to not have to add another parameter to computeLengthDouble and friends. Perhaps this is an opportunity to clean up that code by providing some more useful parameter that can provide the values necessary for the computation.
