* 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)
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.
Game of Life Memory Leak Fix + Other Changes
Fixed memory leak using new. Removed gameoflife struct and reverted back to using pointers to segenv.data (similar to starLeds version).
Added Blur slider. Blurs dead cells slowly to bgColor depending on slider instead of immediately dying. Doesn't effect game logic.
Removed confusing pauseFrames, uses .step to pause now.
Keeps track of last palette used and immediately recolors cells if new palette/color selected. Can be improved.
Changes gameSpeed slider to be more consistent. Speed = updates/second now in increments of 4.
Blur now fades while game is paused.
New blur mode when blur slider is >220
Added variables to make code easier to follow instead of check1 custom1 etc. (not needed)
Removed % with random8 calls.
Misc changes
found a few more places where Serial was used without first checking if its connected.
Arduino docs: `if (Serial)` indicates whether or not the USB CDC serial connection is open. For all non-USB CDC ports, this will always return true
