Frequency Range Selection & Overview

Since I started zero-padding out the fft, the entire 190KHz span can't be viewed at 100% zoom, so I added this very short planar graph at the top which shows the entire span, while the two larger graphs showed a zoomed-in portion of the whole. I need to add a window highlight thing to the overview that shows what section of it the larger graphs are displaying. But it's 3am and I don't want to right now. As a temporary solution, you can arrow-key left/right through the fft.

I added support for option+dragging over a frequency range to highlight it - in anticipation of being able to right-click -> demodulate later on. Some nift-ily rotated text shows the low and high frequency of the selected range.

That's all for now.
