* adding a _fast_ variant of SetPixelColorXY, that does not perform any error checking.
* drawLine uses the fast setPixelColor variant (bresenham algo only)
* for TESTING: segment option "reverse" switches back to the "original slow" code.
surely needs some more optimization and improvements.
First test on GEQ 3D shows 10%-30% speedup
Bug fixes after lots of testing, better settings, etc.
Big thanks to @netmindz for restructuring the code.
Add rough distance stop to Segment::drawLine()
* fix compiler warnings (uninitialized vars, ambiguous functions calls)
* restore some lost function prototypes
* avoid negative pixel indices
* only use "fast" color_add when there is no risk of "overshooting" results
* minor optimizations
* currentBri() is called for any setpixelColor(), so we can speed up everything (a bit) by allowing the compiler to inline which saves a few cycles of call/return overhead.
* aligned the function with upstream, and added another optimization by only calling progress() when a transition is active.
this avoids heap corruption, by double-checking that "use global leds" is not configured, before trying to free ledsrgb[].
It is still a mystery why Segment::_globalLeds == nullptr.
I've found a code spellchecker, so this is what can be corrected easily. Changes are only affecting comments, readme and a few user-visible strings. So no functional impact expected.
* fix some too-long tabs
*author info added
* shrunk number of blank lines
* removed unused audio variables
* colorIndex : better accuracy by first doing multiply, then divide

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.
cleanup:
- version increase
- clean up debug messages
- minor fixes in platformio.ini
- fix compilation with -D WLED_DISABLE_2D
helping the compiler to optimize:
- a few more __attribute__((pure))
- fx.cpp marked a few local functions as "static"
Segments are created/deleted on-the-fly; it seems that "local leds" buffers did not follow properly.
* revise segment copy/move constructors
* de-optimize use of local leds (as they need to be re-allocated when segment size changes)
* minor stability improvements
* handling of stop = 0 when calculating sizes (avoid unsigned underflow)
* make sure groupLength() is never zero (to avoid div/0)
* gapmaps: check for "(gapSize > 0)" added.
not sure if all the checks are 100% needed, but they will improve robustness in corner cases.
* Avoid uint16 underflow in width() and height(): stop > start is possible, and means "inactive segment".
* use size_t for ledsrgbSize, _dataLen and _usedSegmentData - uint16_t could overflow in some situations.
* try to catch attempts to allocate zero bytes (inactive segment => size 0)
* 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

* robustness: Segment::height() should never return 0
* Segment::XY(), Segment::virtualWidth() and Segment::virtualHeight() declared inline in fx.h. The compiler will always inline these functions now, avoiding overhead of call/return. "Knowing" the function body might also enable other optimizations.
--> up to 10% speedup in 2D effects.
FX.h: add ledsrgbSize and allocLeds()
FX_fcn.cpp:
- copy constructor: allocLeds()
- move constructor: no change
- copy assignment: reuse! + allocLeds()
- move asignment: no change
- resetIfRequired: no free
- setUpLeds/resetSegments: allocLeds()
unless...: copy constructor aften called. That is the bad boy causing re-allocs at every effect change!
