Mention another alternate driver for RGBPanels with Adafruit::GFX support and up to at least 256x256, includes unsupported panels like AB/AC and FM6126A

[marcmerlin]

#62 mentions a new driver I just wrote.

http://marc.merlins.org/perso/arduino/post_2020-01-01_Running-FastLED_-Adafruit_GFX_-and-LEDMatrix-code-on-High-Resolution-RGBPanels-with-a-Raspberry-Pi.html explains the new solution in https://github.com/marcmerlin/ArduinoOnPc-FastLED-GFX-LEDMatrix  

This solution allows you to build arduino code so that it works on linux and uses these layers:

• https://github.com/marcmerlin/ArduinoOnPc-FastLED-GFX-LEDMatrix
• https://github.com/marcmerlin/Framebuffer_GFX is the base arduino framebuffer that also supports more 2D arduino code in addition to Adafruit::GFX
• https://github.com/marcmerlin/FastLED_RPIRGBPanel_GFX is the driver that bridges that framebuffer and the APIs it supports (FastLED, Adafruit::GFX, and LEDMatrix), with rpi-rgb-led-matrix for display

please see another Adafruit RGB matrix driver for popular STM32F103 (bluepill) board (Arduino code)
It works with HUB12 Monochrome 32x16 panels, with wide spectra of HUB75 RGB displays (many sizes - 32x16, 64x32. 64x64, 80x40, 128x64, differnt scan and connecting schemes, and also support HUB08 two-color panels
