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.
* 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

* PSRAM_Allocator was missing the "reallocate" method, which lead to undefined behaviour when dynamic JSON doc needed to grow/shrink
* Segment::setUpLeds() quickfix for length() == 0 (should not happen, but it did happen for me once)
* leds in PSRAM causes major slowdown on wrover boards - disabled.
* prevent string buffer overflows (stack corruption)
* avoid division by zero (program might crash)
* avoid log(0) which is undefined, too
* use faster math routines for float (logf, powf)
* use size_t instead of uint16_t -> prevents random behaviour (corruption) in case that JSON files get larger than 64Kbytes.
* use a constant for max large file space (was UINT16_MAX)
* reduced the scope of some functions and variables to "static" - avoids name clashes and may support better optimization by the compiler
* Improve indent
Improve indent, so its more allignend and correctly indented according to logic groups
* Spaces to tabs
