RecordHandler pops out of thread into main thread. Need to push to FFTView or TimeCrawlView or do I do math inside thread?

- in portrait capture and move to FFT view.
- scroll view doesn't have the correct grid spacing, make the grid programmatically
- needs to slow down audio polling and hook in play button and add in process and viewing realtime result
- connect up audio polling to drive SurfaceView updates
- pulled out system UI hide and will refactor that separately
