- removing WS2812FX::setMode()
- removing WS2812FX::setColor()
- removing floating point in transition
- color handling modification in set.cpp
- replaced uint8_t with unsigned in function parameters
- inlined WS2812FX::isUpdating()
- (MAY BE BREAKING) alexa & smartnest update
- Added pre-calculation for segment brightness: stored in _segBri. The impact on FPS is not huge but measurable (~1-2FPS in my test conditions)
- Removed `bool unScaled` from `setPixelColor()` function again (it has no/minimal impact on speed but huge impact on flash usage: +850 bytes)
- Removed negative checking in `setPixelColorXY()` and replaced it with a local typecast to unsigned, saves a few instructions (tested and working)
- Changed int8_t to int in `moveX()` and `moveY()`
- Removed a few functions from IRAM as they are now not called for every pixel but only once per segment update
- Removed a `virtualWidth()` call from `ripple_base()`
- Bugfix in `mode_colortwinkle()`
uint16_t to unsigned to make it consisten throughout the hand-down.
colorFromPaletteWLED now returns uint32_t which saves the conversion to CRGB and back to uint32_t (in most uses at least).
also added (preliminary) CRGBW struct. I tried to use it in place of uint32_t colors but it adds a lot of overhead when passing the struct so reverted to uint32_t in most places.
updated a few FX to use the CRGBW struct and also cleaned some code to improve flash useage.
- blurring now uses desaturated adding: it is faster most of the times and blurring adds scaled colors so should rarely (ever?) saturate, I saw no visual difference in tests.
- formatting
- optimized color_add() again: now it is as fast with preserved ratio scaling than the "fast" variant was before (if no scaling is needed, it is even faster). plus it saves 250 bytes of flash
- bugfix in `color_fade()`
- removed a lot of whitespaces
* speedup: add functions to only blur rows or columns (50% faster)
* fire2012: tinkering with bur options. Vertical blur only when slider < 64 (faster); extra blur for slider values >192 (bush burn)
-changes save roughly 600bytes of flash
-made blurring faster by not writing the color and then reading it back but keeping it as a variable: on a C3, FX black hole goes from 55FPS to 71FPS
-added optional parameter to blur (smear) that can be used in combination with SEGMENT.clear(), blurring the frame without dimming the current frame (repeated calls without clearing will result in white). this is useful to blur without 'motion blurring' being added
-scale8 is inlined and repeated calls uses flash, plus it is slower than native 32bit, so I added 'color_scale' function which is native 32bit and scales 32bit colors (RGBW).
- transitions always enabled (use delay 0 to disable)
- optimisation in on/off fade
- fix for palette/color blend when blending style is not fade
- various tweaks and optimisations
