Re: [Discuss-gnuradio] New OpenGL-based FFT, Waterfall, and Scope displa

The waterfall rate is exactly like the fft rate: a decimation is computed so that the actual rate of fft frames per second (from the log power fft block) is approximately the given fft rate.

The reason for adding a new preference is that the CPU and graphics requirements are different for the waterfall plot, so it should have its own separate configurable rate.

I think we need another preference parameter for the "waterfall rate". It
should not be the same rate as the fft rate.

Howabout "waterfall_rate"?

OK.  What are the units, and how would it behave?
