it seems that SEGMENT.blur() is the main bottleneck for many 2D effects.
This change optimizes performance of the function:
* avoid to re-write unchanged pixels
* early exit when blur_amount == 0 (=nothing to do)
* use _fast_ types where possible
I've seen up to 20% speedup with this change.
power estimation results from estimateCurrentAndLimitBri() were too low (example: estimated 1.3Amp, measured 1.6Amp). This change corrects the power calculation. Due to the changed behavior of getPixelColor, powerSum must be used as-is, not scaled down again by brightness.
this optimization avoids to apply brightness two times .
NeoPixelBusLg has already applied global brightness at sPC. Due to internal working of the Lg bus, its sufficient to only post-apply scaling, and set the new (scaled) brightness for the next frame.
I still see strange crashes in setPixelColor/GetpixelColor, which ssem to come from race conditions between async_tcp (change presets) and looptask (strip.service).
To make the situation better, its important that any global pointers are reset to NULL immediately after free().
* Avoid uint16 underflow in width() and height(): stop > start is possible, and means "inactive segment".
Without these checks, it was possible that width() and height() produce VERY large values due to underflow.
* adding an optional parameter to setBrightness(). ApplyPostAdjustments() will only be called if `immediate=true`. Only ABL will use immediate=true, to ensure electrical safety of equipment.
This allows some optimizations of performance, as ApplyPostAdjustments() is time consuming.
* busses.setBrightness(bri) --> applied to all future pixels (fast, lossless)
* busses.setBrightness(bri, true) --> applied directly to all previously set pixels (slower, lossy)
* Changes for allowing Alexa to change light color to White when auto-calculating from RGB
* Update alexa.cpp
Indention
* Do not rely on global auto white override
(gets white mode from segment light capabilities)
* alexa.cpp: Removed unnecessary whitespaces

One pixel segment handling.
- added 0D FX metadata (1 pixel effects)
- ignore palettes for White only segment
- ignore color for non-RGB & non-White segment (on/off)
Bugfix
- proper auto segment creation
- hide palettes for non RGB segments
- some tweaks for #2984
- force Solid for some FX (causing crash) on 1 pixel segment
UI Optimisations
- slider tooltips
- tiny bit smaller tooltips
- hide segment power if only one segment
- gap between sliders
