Details:

hg id: f9b7aa3b88f8

graphics_toolkit("fltk")
loglog(abs(fft(rand(1,100))))

and pan with mouse

I think there are to problems with loglog:
1.) It NaNs out. There should be a border which prevenst this
2.) While panning, the data gets zoomed/scaled

-> The panning function needs to be special cased for loglog.
