calculating fov for the max zoom

Hi,

I am setting the maxpixelzoom attribute for the view element in the xml. How can I calculate the (s|h|v)fov for this maximum allowed zoom in the current window size other than by zooming in, getting the fov, and then zooming back out?

Well, I have found the answer myself and I'm posting it here for anyone having this problem in the future Actually, it turned out to be trivial: just use the view.fovmin variable, it gets constantly updated even if not set initially.
