* made cols/rows integer, to avoid that "cols-x" wraps around
* pre-compute some expressions that don't depend on loop counters
--> wins us 1-4 fps on my 72x72 test setup
* add more accurate version of map() - reduces slight flickering in some 2D effects
* cache fftResult[] in effects (um_data->fftresult might get updated while the effect still calculates)
Only draw what will be visible.
This is a pretty solid speed increase when the adjacent bar is close in height, or if it's taller and would occlude it anyway, it'll be skipped.
* 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()
AC minor patch cluster
* Anti-Aliased Lines and Circles
* replacing deprecated functions in ws.cpp
* using global brightness in analogue clock overlay
* fix for palette names (custom palettes)
* bugfix for UI: when resizing the window, it always jumped to the Colors tab
* UI: add webpage shortcuts for tabs
There were three problems here:
- AsyncWebServer is going to copy to a heap buffer anyways, so we might
as well just pass it one it can use
- The buffer size estimate was wrong -- we need 9 bytes per pixel
("RRGGBB",), so the buffer could overflow, and it was not
considering the extra 2D requirements
- On ESP8266, the stack allocation was overflowing the stack, causing
corruption and crashes.
