General (for CE, but also used by M12_pArc)
- add drawArc
Custom Effects
- add WLEDSR Custom Effects comment to places in WLED where it is hooked in
- move from wled.json to wledv123.json
- rename matrixWidth/Heigth to width/height and use virtualWidth/Height
- remove setPixels
- add drawLine / drawArc
- Un-F() most segment JSON keys, decreases JSON doc usage by 47 B (increases static RAM usage by 32 B),
makes `extractModeDefaults` work without strstr_P
- Removed String from serializeModeData and serializeModeNames
- Set 0.14 version name "Hoshi"
also when user wants less than 16 bands.
Previously when users selected fewer bands (like 4 instead of 16), only the lowest freq channels were displayed.
... found that stupid commit messages get more attention ;-)
- use 22050 Hz for sampling, as it is a standard frequency. I think this is the best choise.
- redesigned the GEQ channels (fftResult[]) for 22Khz, based on channels found on old HiFi equalizer equipment. 1Kzh is now at the center; Bass/Trebble channels are using 1/4 on left/right side respectively - similar to real equalizers. Looks nice :-)
- adjusted effects that use FFT_MajorPeak so that the maximum frequency is supported.
- new feature: "Input Level" (info page) can be used as global "GEQ gain" - only when AGC is ON (was already possible when AGC=off)
- some parameter tweaking in FFT function
- hidden feature: FFT decay is slower when setting a high "dynamics Limiter Fall time" (steps: <1000, <2000, <3000, >3000)
- FFT_MajorPeak default 1.0f (as log(0.0) is invalid)
- FX.cppp: ensure that fftResult[] is always used inside array bounds
- removed broken FFTResult "squelch" feature. It was completely broken, and caused flashes in GEQ.
- added Frequency scaling options: linear and logarithmic
- fixed a few numerical accidents in FX.cpp (bouncing_balls, ripplepeak, freqmap, gravfreq, waterfall)
