e0af34cb5f More FFT fun: No point in computing and combining the 2nd FFT if it's just being made null. Use the regular complex FFT (called by fftr anyway) and save ram and computation for a given number of bins.

7e538995a5 FFT plugin: Some speed regulation for too-fast targets. (50FPS)

e208b74915 FFT plugin: give everything in the main file a nice 'static'-ing. Saves approx. 1-3K size depending upon the target and so should speed it up a bit.

ff2d224ae7 FFT Plugin: Should use scale_factor, not LCD_WIDTH/HEIGHT to break the spectrogram loop.

30e2f42c82 FFT Plugin: Revamp the main code to rid it of 64-bit math. Use 32-bit kiss_fft_scalar because 16-bit integers are generally a poor choice for computation on-target. Simplify display code to speed it up. Add logarithmic frequency display (need keymappings, guessed on some). On dual-core, perform FFT on COP. Add some support function to fixedpoint.c. ... and stuff.

af466f3cbf FFT plugin: eliminate 64-bit math. This should result in faster and probably more accurate calculations.

f7a30a4b08 kiss_fftr appears to perform two real-valued ffts in parallel -- so feed it only one signal of size N/2 (as opposed to splitting a single signal of size N into two interleaved parts which is what it seemed to be doing before)

43264a946f New plugin: FFT, A frequency analyzer plugin 
There is some more work needed:
- Keymaps are definitely not perfect, touchscreen targets are disabled due to no keymap
- There is no manual yet
