this is a band-aid fix for random crashes when switching between presets with multiple segments - crossfade disabled.
!! adding type initializers fixed it for me on -S3, however I still see (less frequent) crashes on esp32, due to heap corruption.
It took me hours to get a meaningful stackdump:
assert failed: heap_caps_free heap_caps.c:360 (heap != NULL && "free() target pointer is outside heap areas")

update for lost balls
Added some protection - so that when intensity is lowered and raised some time later balls that have moved way off the track are recovered.

Added Ball Track V1
In this version the balls bounce of the edges and do not interact with one another.
bracket was on wrong position, resulting in this warning:
wled00/set.cpp:357:79: warning: value computed is not used [-Wunused-value]
strlcpy(mqttGroupTopic, request->arg(F("MG")).c_str(), MQTT_MAX_TOPIC_LEN)+1;
oappend() silently discards strings when the buffer is full, leading to strange effects like half-working UI pages.
The new debug message will help developers to understand what could be wrong.
- breaking change
- remove leading 0 checkmark
- add reverse scroll checkmark
- add vertical scroll if text fits into segment (intensity ==0 or ==255)
- rotated characters
- leading 0 check added to short texts (i.e. #DDMM0)
Fixes#3322
* Blurz and a few other effects would crash (or behave unexpectedly) for single pixel segments
* replaced a few "MAX" by "max", because MAX will evaluate its arguments twice so its very inefficient.
changes from 3.50 to 3.6.0:
* bugfixes
* removed "register" keyword
* some speedups
* explicit bool() and uint32_t() operators, see https://github.com/FastLED/FastLED/issues/819
FX.cpp: bugfix for "wled00/FX.cpp:4906:36:
error: cannot convert 'CRGB' to 'uint32_t' {aka 'unsigned int'} in initialization"
turns out that fastLED 3.6.0 has an explicit uint32_t operator that returns RGBA, however 3.5.0 does not have this and the conversion returned only the "red" component".

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)
