* separate mutexes for improved performance:
- busses.show and effect drawing
- critical changes to segment vector
- block out critical segment changes while strip.service() loops over segments
* UDP realtime acquires mutex before drawing
- prevents corrupted outputs, caused by parallel tasks updating pixels while busses.show() runs
* segment::fill() is also called outside the service loop - make sure that size is always calculated correctly
* leave _currentSeg in a meaningful state after strip.service()
- add buttons for PixelForge and PixelArt (settings page, below "file system" button
- abort build when PixelForge requested but GIF support missing
- "support" PixelMagic with error message - known issues with bigger images
revised mutex and critical section handling for segment drawing
- simplified code with macros (no more #if ESP32 ... #endif)
- remove some critical sections (prevents interrupt stalling)
- added mutex to functions that change the list of segments
- added mutexes to all (potential) background drawing code
- use recursive mutexes to prevent accidental self-locking of tasks
* protect pixel buffer changes with critical section
* protect segment list modification with critical section
* make _isServicing and _triggered atomic (move out of packed bitarray)
* allow custom timeout for waitUntilIdle - DDP needs a longer timeout
* protect strip.show() and effect drawing functions with mutex, to prevent crashes
replaces the pixel magic tool with a much more feature-rich tool for handling gif images. Also adds a scrolling text interface and the possibility to add more tools with a single button click like the classic pixel magic tool and the pixel-painter tool.
-> distortion waves 3x speedup
-> hiphotic 2x speedup
-> waving cell 1.5x speedup
* replace sin8_t by lookup-table with pre-computed values
* moved integer sin and cos to fcn_declare.h (inlined by the compiler)
* moved gamma32 to fcn_declare.h (inlined by the compiler)
* a few other small tweaks
* added vLength(), vHeight(), vWidth() and mapped them to their WLED-MM counterparts
* added SEG_W and SEG_H macros
* minor variable renaming to avoid name clashes with vWidth, vHeight, vLength
- fixed "jumpyness" by improving offset calculation resolution
- added palette support
- added two rendering modes for use with palette: one uses hue-mapping, one uses brightness mapping
- added alternate animation mode (from initial source)
- extended scaling: zoom checkmark (depends on matrix size)
Sends a shimmer across the strip at defined (or random) intervals
Optional brightness modulators: sine or perlin noise
Can be used as an overlay to other effects.
