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.
minor optimizations that give up to 10% speedup in my tests
* use "fast" integer types (where possible)
* replaced _bri with _restaurationBri (no use of globals)
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.
due to `if (strip.isUpdating()) return;` reading the encoder did not happen in time if the strip was active - with high number of LEDs, this means "always updating". Similar observation that we had with the audioreactive usermod, and similar solution.
* 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)
* Adding Pixel Magic Tool to WLED
* Revert "Adding Pixel Magic Tool to WLED"
This reverts commit b4f08fa8d5.
* Adding Pixel Magic Tool to WLED
* Corrections and performance improvements
* Remove IE compatibility tag
(saves a few bytes and IE10 is over 10 years old and unsupported)
Correct HTML language attribute
(Chrome would show a popup asking to translate from Portugese)
* Corrections and performance improvements
* Enable pxmagic by default

* allow user to control rotation speed (c3 slider)
* preserve accuracy by performing division _after_ multiplication: " (i * speed) / 32", instead of " i * (speed / 32)"
* proper rounding of "map" results, for better visual appearance
* avoid division by zero in map() function
