* use a more meaningful max universes limit of 112 (safe up to 128x128 pixels)
* accept more universes, but only track sequences for the configures max universes
* made e131LastSequenceNumber[] local (its only used in e131.cpp)
This disables bus caching (and related speedups) while receiving realtime UDP pixels.
Its still totally unclear to me what happens, and why disabling the cache solves problems.
controls the number of phases shown by the effect
breaking - the old code was using a fixed width per wave, while the new one always fits the same number waves into the panel width.
speedup, accuracy improvements and enhancements:
* separated calculations in float from integer
* improved time resolution
* slow down effect on for dimensions >32
* added original "twin" option
* added customizable blur (thanks dedehai)
* made effect time-defendant (instead of framerate dependent)
* made effect a bit slower
* fixed physics
* made dropping more random (avoids skipped rows)
* drop traces look better now
* made bounce more realistic
* prevent off-screen drawing
* new setting in UI page: "Don't use effect palette and segment parameters" - only meaningful when "Use effect default parameters" is enabled, too.
--> effect slider defaults will still be applied, however palette, 1D2D mapping mode and other segment settings will not change.
adding hints for the compiler for optimization.
In case your custom build complains about "const", just remove the keyword. based on e82f38e277, but going further :-)
* "const" class functions : function does not modify any class attributes ( --> "this" becomes const)
* __attribute__((pure)) : function return value depends only on the parameters and/or global variables. The function does not modify any global or static variables.
* __attribute__((const)) : function only examines arguments (no globals), and has no effects except the return value. This slightly more strict than "pure"
* hot: tells the compiler "this functions is called very often"
* cold: the opposite of hot
* mode_2Dfloatingblobs() improvements for large panels
* Segment::fillCircle() speed optimizations
* HUB75 hack (disabled by default): skip first fill(BLACK) when using double buffering (as the buffer gets cleared after each frame)
* cache width, height, and a few more values that are normally re-calculated for each pixel
* make normal sPC a bit faster
* Segment::fade_out() optimization
--> only active in FASTPATH mode, to preserve flash on small devices (8266)
--> code still needs some polishing
--> up to 20% speedup with some 2D effects (esp32, flash qio 80Mhz, -O2)
* bring back lost parameter "Fall ratio" (MM specific)
* stabilize the math, avoid rounding errors and unsigned overflows
* speed limit for long strips added
* gravity reduced slightly
