* advanced config: expose hidden constants to user screen * advanced config: add support for FFT window overlapping * waterfall: display at native resolution on high-DPI screens * waterfall: add cursor and improve label density * FFT: fix normalization so that 0 dBFS matches full-scale sinewave * FFT: decouple data acquisition from processing and display * FFT: separate lock for reallocation (to avoid some needless waiting) * moved ranges and other constants to a separate file * debug: better performance measurements * minor fixes * build the ringbuffer library as part of LMMS core
